AOMC Motorcycle Club forum 2019

Chair:  Keith Mortimer AOMC President.

Guests:  John Lewis (CPS Policy, VicRoads), Shane Ellis, Lee Johnstone  (Safety & Compliance VicRoads).

John Lewis (VicRoads) gave an introduction to the forum. 2009 CPS changes accelerated vehicles on CPS from 8500 to 30,000 by 2014. At the time there was concern from car clubs about the modifications being made to vehicles and the lack of oversight and clear standards. VicRoads introduced the M plate scheme for modified CPS vehicles. At the time there was discussion but no consideration over the issue with motorcycles.  Happy to start talking about motorcycle modifications.

Questions from the floor:

Is there an M Plate for motorbikes?  A: No. Have to meet RW requirements and VSI – 4 requirements. In theory, motorbike cannot be modified beyond VSI-4.

Self assessment can be done on motorbikes up to 1949. In our club (Vincent) the bikes went out of production in 1956 but are still basically the same bike that was produced in the 1940s. Seems unfair that the same bike has different treatment depending on date of production.  A:  Had to be some cut off date. 1949 was considered the start of most modern vehicle systems and hence the date that ws introduced. No matter what year was picked, same issue would have arisen. Has to be clearly defined points to classify. As soon as one exception is made, it opens flood gates for other vehicles. Have to maintain consistency.

If a car is put on H plates and is then modified, does it keep the H plate or does it have to have an M plate?  A:  When a VASS report is done an M plate is issued. Have no information on database of what modifications have been done. Rely on clubs and public to report vehicles that should be classified differently. Follow up these reports with a letter to the club and owner to prove the car is not modified beyond specifications or provide engineers certificate. Have even been sent You Tube clips of H plate vehicles in drag races. VicRoads have a dedicated email address for these reports.

BSA Owners Club has over 600 bikes on CPS. Keeping of records by clubs seems to be double handling and time consuming as clubs, RW testers and VicRoads all keep and administer these records. A:  VicRoads are keen for clubs to keep records because at times they need to go back to the club to prove vehicles have been inspected properly. Makes clubs responsible for the condition of the vehicles.  It is also a protection for the club.

VicRoads do a great job but have limited resources. Shouldn’t clubs be more responsible and demerit point system introduced, as if there are no penalties no one cares. A:  Police are issuing fines for unroadworthy and over modified vehicles without proper certification. When vehicles are reported to VicRoads and a letter is written to the club, usually the clubs take the matter very seriously. Many illegal modifications are done after the club and VicRoads have issued permits for the vehicle, which was acceptable at that time. Similar things are happening with late production vehicles and VicRoads are cracking down on certifiers who pass these vehicles as fit for road use.

Monarchs Motorcycle Club require members to sign a form each year stating their bike has not been modified, and also have an attendance requirement so vehicles can be sighted. Other clubs do annual checks on vehicles, but not all can be seen. There are some clubs that offer CPS membership for $100 and never see the vehicles.  A. VicRoads do audit clubs that have been reported as being ‘Dodgy’.

What is an e roadworthy?  VicRoads are in process of transferring roadworthy testing to an online system rather than a paper based system. This means all records and photographs can be stored on a database. These records will be kept in a cloud

Do VicRoads keep stats on convictions of people doing the wrong thing, such as false plates and shared plates?  No, VicRoads do not have that information, perhaps the police do.  Not aware of any stats they might have. VicRoads looking at technology to link plates to the car to identify theft and cloning, which may eventually be linked to the CPS.

What is VicRoads view on replica vehicles on CPS?  At present, VicRoads recognises bikes as what they claim to be, so a 2015 replica of a historic model is eligible. If a bike is identified by a compliance plate, that is its identity forever. There are a number of bikes on the system they believe are not in the spirit of the system, John Lewis will be sending out information to clubs on what the rules regarding replica motorbikes are.

When log book scheme first came in there were only 300 clubs in Victoria. Now there are more than 1300 clubs. Could VicRoads look at the situation where people go out and form clubs with only 6 or 7 people.  A consultant was engaged to go out and talk to clubs, and will come up with a set of criteria that can be used to determine if a club is legitimate.

Have VicRoads ever taken a clubs permit facility off them?  Yes, over time some clubs have been closed from the CPS.

How do clubs accommodate things like the cafe racers and Japanese bikes that were built without an ID plate without the facility of an M plate?  If the bike has been modified away from its original configuration and beyond VSI-4 guidelines, the owner and club would be encouraged to engage with a VASS signatory to look at the vehicle and check it for fit for purpose. The clubs could use this as an assurance that the bike is within the rules. VicRoads acknowledge that the same consideration to modifications in cars has not been given to motorbikes and needs to be addressed. VicRoads need to ensure that any modifications have been done safely.  Part of consideration from this meeting is to get feedback and support from clubs as to how modifications on bike could be self certifying or an independent signatory could be bought in to certify.

Rorting of log books has been occurring. Is there any thought of introducing a phone app log book?  VicRoads have had some thoughts of looking at apps or electronic log books similar to the learner log book. Have not progressed very far. Have tried to alter logbooks to make it harder to tamper with entries. A lot of club members are against the idea of e-log books, but it may come to being if rorting continues.

After market frames made by Rickman for bikes like Kawasaki ZA that are pre engineered are bought out as an extra component that is street legal. Do you still need a VASS engineers report if using one of these.  If it is not a Kawasaki frame from the original manufacturer, it comes under the category of an individually constructed vehicle (ICV).  Would need to speak to a VASS engineer.

Rickman bikes were sold in the 70s and there are plenty around.  They have been road registered with VicRoads all this time.  Legacy challenge if a ICV was built in the 70s. Records would reflect that and would be treated accordingly. If it has never been registered it would have to be treated as if built yesterday.

When out with club on a multi day rally, the rules are that you cannot fill your log book out in advance, but have to record each day on the day. Can you explain why?  Do not want books pre filled in so that people do not fill out book entry quickly as policeman is approaching vehicle.  

One attendee recounted how he was on a 3 day club run and he always prefills his log book for each day with dates and where he is going. Was pulled over by police who knew CPS inside out and said it was all good to fill in that way, but said that you might be wasting a day or two of your allocation if you pull out of the run or have a mechanical.  Not the reason for no pre filling, always merely over being able to quickly fill in when stopped. 

Could you clarify commercial use in terms of advertising displayed on vehicles?   CPS set up for private use, but some have heritage advertising.  There are some vehicles that advertise current businesses. Only used for display, and not used for carrying goods so is a grey area.

Car is taking part in a charity rally with logos on it and is on CPS. How is this viewed?  Is still being used for private use rather than commercial use.

Recently have had bikes knocked back in regional Victoria when applying for CPS after being passed by scrutineer. Reason was scrutineer signed off that member was financial, and VicRoads officer said this had to be signed by appropriate club official, not the scrutineer. The form that is submitted with signatories are in 2 parts. Top part is the club officials who can sign applications & renewals to verify membership. Second part is the scrutineer part where the scrutineer signs. Can only sign the renewal if name is on the top part.

Recently had to get a RW on a 2 year old vehicle and was told that he had to have a noise test which entailed the bike going off to another business for several days. Another tester approached said it did not need a noise test. Which one is correct?  If there are requirements for a roadworthy to have a noise test, then tester would have to demonstrate that he has taken that step. Roadworthy tester in the audience reported that noise testing only needed if muffler does not meet specifications.

Any conversation/instruction with VicPolice re what to look for in regards to M Plates?  Are undertaking a project of informing VicPolice on defects and modifications. Should be rolled out within the year. VicPolice approached VicRoads on this matter, and technicians have met with instructors at the police academy.

The CSTeam section of VicRoads have a very difficult and lengthy process. No telephone contact available so cannot talk to anyone. How can communication be improved?  Like contact to be via email so as to keep track of enquiries and send out to appropriate area. There is a customer resolution team that can be contacted.

Frame straightening, what is VicRoads view on this?  Like engine or fork replacement, when bike moves further away from original manufactured vehicle. There is a section of VSI-4 that permits repair or modification. Anything deemed beyond that level of repair would need a VASS certification.

Pre 1960 bikes do not have indicators. Can VicRoads include in motorcycle awareness information for car drivers to recognise motorcyclists using hand signals.  Is certainly in the regulations that if turning signals not present, then hand signals are allowed.

Member of club is building a bike with a Rickman frame at present. What should I do when he presents it for scrutineering? Will need to get a VASS certificate if it has never had an identity.

Chairman Keith Mortimer suggested that as the Rickman issue is quite complex, the clubs and VicRoads need to get together on this issue to discuss. VicRoads attendees are happy to do.

CPS is eligible when 25 years old to the day. A member started process on date of 25 year anniversary and VicRoads officer knocked him back and told him he had to wait another month to apply.  If compliance date only gives month of build and not exact day, then it is considered to be at the end of that month for CPS eligibility purposes. A manufacturers or dealers letter would be sufficient to verify exact date. 

Problem is that John Lewis knows the rules when you speak to him on phone, but not all front desk officers are as aware.  Front desk officers need to cover a huge area of rules and regulations and in the main they are right, but mistakes can be made. They do also contact the technical team to get verification.

Who do VicRoads consult regarding safety legislation on motorcycles, such as wire rope barriers and maintenance.  VicRoads has regular meetings with Road User Access group, TAC and what used to be called motorcycle advisory group. They are very strong advocates for motorbikes.

I have never seen any accreditation or incorporation requirements for clubs that are registered for CPS?  Is not a requirement for clubs to be incorporated. AOMC have recommended to clubs to be incorporated to protect office bearers.

Most modifications on a motorbikes are for safety reasons. Do we have a list of what police would be looking for in modifications?  When you start modifying vehicles, there are fundamental elements of its performance that need to be considered under ADR requirements. Modifications on motorbikes are more difficult than cars. Project will need to be in consultation with experts and VASS engineers. Police need to be able to make informed judgements on the side of the road.

John Lewis thanked everyone for having them along tonight. Summary of this evening and what VicRoads are taking away is that:

  • Clubs do not want more regulation of the CPS, but would like stricter enforcement of the rules.
  • Concerns about contact with VicRoads both in being able to telephone correct area and be kept in communication loop with information.
  • Clarification on individually constructed bikes and use of aftermarket frames.
  • When e roadworthy introduced will look at the need for storing photographs.
  • Team want to be more engaged with the motoring community, particular around modifications and maintaining the integrity of the scheme.

 Image EPA confirms ethanol causes damage !

The American Environmental Protection Agency has acknowledged that overheating and component failures can be caused by ethanol in fuel. A media release from the American Motorcyclist Association says that the U.S. Environmental Protection Agency has publicly acknowledged that ethanol in gasoline can damage internal combustion engines by increasing exhaust temperatures and indirectly causing component failures.   The EPA statements are found in a rule proposal issued by the Federal Trade Commission regarding a new label for pumps that supply fuel blends high in ethanol.According to the EPA: “Ethanol impacts motor vehicles in two primary ways. First … ethanol leans out the [air/fuel] ratio (increases the proportion of oxygen relative to hydrocarbons) which can lead to increased exhaust gas temperatures, increased piston crown temperatures  and potentially increase incremental deterioration of emission control hardware and performance over time, possibly causing catalyst failure.“Second, ethanol can cause materials compatibility issues, which may lead to other component failures.” The EPA statements back the long-held position of the American Motorcycle Association, which has fought the distribution of E15 fuel blends in an effort to protect motorcycle and all-terrain vehicles from the damage that ethanol causes. “Now the EPA acknowledges that ethanol itself is harmful to emissions hardware and other components on all motor vehicles,” said Wayne Allard, AMA vice president for government relations. “It is time for the federal government to pause, take a hard look at this product and change its entire approach to ethanol in fuels.” E15 is a formulation that contains up to 15 per cent ethanol by volume. The EPA has proposed rule to roll back the requirement for wider distribution and use of E15 under its Renewable Fuel Standard. In Australia, the most common fuel blend that is sold in Australia is E10 – 10 per cent ethanol blended with 90 per cent petrol. E85 blended fuel with 85% ethanol is also slowly being adopted.  Within the EU, the use of ethanol in fuel is strictly restricted to E5, being just 5%.

REASONS WHY ETHANOL BLENDED PETROL IS NOT RECOMMENDED FOR USE IN OLDER VEHICLES: Introduction 

The Federal Chamber of Automotive Industries provides the following information which outlines the key reasons why vehicle manufacturers do not recommend the use of any ethanol/petrol blended fuels in vehicles made before 1986. Ethanol has a number of important chemical and physical properties that need to be considered in a vehicle’s design.

Carburettor Equipped Engines: Vehicles made before 1986 vehicles were predominantly equipped with carburettors and steel fuel tanks. The use of ethanol blended petrol in engines impacts the air/fuel ratio because of the additional oxygen molecules within the ethanol’s chemical structure. Vehicles with carburettor fuel systems may experience hot fuel handling concerns. This is because the vapour pressure of fuel with ethanol will be greater and probability of vapour lock or hot re-starting problems will be increased. As a solvent, ethanol attacks both the metallic and rubber based fuels lines, and other fuel system components. Ethanol also has an affinity to water that can result in corrosion of fuel tanks and fuel lines. Rust resulting from this corrosion can ultimately block the fuel supply rendering the engine inoperable. Water in the fuel system can also result in the engine hesitating and running roughly.

Fuel Injected Engines: In addition to the issues mentioned above for carburettor equipped engines, the use of ethanol blended petrol in fuel injection systems will result in early deterioration of components such as injector seals, delivery pipes, and fuel pump and regulator.Mechanical fuel injection systems and earlier electronic systems may not be able to fully compensate for the lean-out effect of ethanol blended petrol, resulting in hesitation or flat-spots during acceleration.Difficulty in starting and engine hesitation after cold start can also result.

Exhaust And Evaporative Emission Levels: Lean-out resulting from the oxygenating effect of ethanol in the fuel may affect exhaust emissions. Of more concern is that fuel containing ethanol can increase permeation emissions from fuel system components, particularly those that have aged for nearly 20 years. Therefore the increased vapour pressure of fuel with ethanol will lead to increased evaporative emissions.

    New” Oils and “Old” Cars Don’t Mix

By Mark D. Sarine

Have you heard about the “zinc” problem with modern motor oils? Many classic car owners and racers have experienced camshaft failures due to modern motor oils. Even worse, be prepared for the “zinc” to change in motor oils again later this Fall.

If you’ve not had the pleasure of having your camshaft go flat due to modern motor oils, consider yourself very fortunate. As an owner of an engine parts warehouse, I’ve seen hundreds of perfectly good camshafts ruined by modern motor oils. So when I read about the “new” API SN motor oil coming out this Fall, I started talking to the engine builders we supply parts. The engine builders all said the same thing – car owners don’t much know about these modern motor oils and the problems these oils create in classic cars and race cars. Knowing about the Cruise News, I contacted Mike to see if he could help us spread the word – modern motor oils are not good for your classic hot rods and race cars.

Here’s the facts:

“Zinc” or ZDDP as it is commonly referred to in motor oils is a type of chemical called Zinc DialkylDithioPhosphate, and “Zinc” has been the most common anti-wear additive used in motor oils for the last 60 years. I just call it “Zinc” because it is easier to say and spell.

“Zinc” is a remarkable chemical that protects engine parts from metal to metal contact under heavy loads.

“Zinc” works by creating a film on the iron and steel parts in your engine. Unfortunately, “Zinc” also creates a film inside modern Three Way Catalytic converters. This “Zinc Poisoning” limits Three Way Catalytic converter life to around 70,000 miles.

The Federal Environmental Protection Agency (EPA) mandates that car manufacturers warranty Three Way Catalytic converters on new cars built since 2004 for 120,000 miles.  To achieve this goal, the car manufacturers worked with the American Petroleum Institute (API) to create new, lower “Zinc” oils that allow Three Way Catalytic converters to live for 120,000 miles.

These new “Lower Emissions” oils have extended catalytic converter life, but they have shortened the life of flat-tappet camshafts.

Not long after these modern motor oils with less “Zinc” hit the market, we started to notice an increase in flat-tappet camshaft failures. At first, it was the race engine builders, so we shrugged it off as some new “trick” the race guys were doing that caused the problem. Then we started to see stock flat tappet camshafts going flat.

Things got ugly really fast. Every camshaft company started researching the problem. So did the Automotive Engine Rebuilders Association. Everybody wanted to know, why are cams going flat?

The answer was “Zinc”.

Lower “Zinc” oils work just fine in modern production car engines with overhead cams, and roller lifters. These modern engines don’t rev past 5,000 RPM.

Most hot rod and race motors have push rods, flat tappet lifters and rev beyond 5,000 RPM. These engines need motor with more “Zinc”.

The good news is that “High Zinc” oils are available.

If you have a classic car or race car, I highly recommend using the Joe Gibbs (or Penrite) brand oils.

We have seen a dramatic reduction in camshaft problems when our engine builders started using the Joe Gibbs brand oils. Since Joe Gibbs Racing is a NASCAR team, they are on top of all the latest advancements in technology, and they have developed oils that work. I’ve seen used parts from Joe Gibbs Racing engines that look brand new (even with over 600 miles on them).

If you’ve not had any problems so far, consider yourself very lucky. Switching to a “High Zinc” oil before the new API SN oils hit the shelves is like an insurance policy against having problems.

We like selling engine parts, but I hate seeing good parts go bad – Especially when they don’t have to.

  ETHANOL BLENDED FUEL.(Thanks to Classic M/cycle Club of S.Aust)

What is Ethanol? Well in simple terms it is alcohol distilled from waste green vegetation, like sugar cane. Australia accepted this as a boost to the cane industry as well greening our fuel.

There has been much talk about Ethanol and it’s effects when added to our petrol

but no one wants to make an official statement, in fact no statements of any kind have been made officially that answer our questions, or in essence to help to solve the new batch of problems that have arisen from tampering with our petrol. You be the judge.

The oil refineries now only make unleaded petrol, so additives, like ethanol are added to boost octane ratings up from what is really the old standard petrol. Ethanol is not the only additive used for this purpose, just the cheapest, and the most common. Australia had a limit set at 10 % (E10) but many samples show near 20% is being used, with this being planned as a new standard.

Some of the problems we have heard about are listed below.

• Hard starting in damp weather.

• Water in fuel. Blocking filters.

• Poor economy in normal everyday use.

• Dissolves tank sealant.

• Plays hell with fibre glass tanks. Disolves them and the mess causes engine siezure.

• Corrodes metal fuel tanks causing petrol leaks

• If sitting for a couple of months, corrodes most metals.

• corrodes inside the fuel jets causing lean mixture, and blockages.

• Rots fuel lines and tap seals, fire danger in the shed.

• Has a short tank life of about a month, and unstable octane rating.
 
•Swells rubbers in petrol taps and eventually stops petrol flow

This is a long article but it is well worth reading. The implications are worrying.
OIL IS KILLING OUR CARS & M/Cycles!        By: Keith Ansell, Foreign Parts Positively, Inc.
About a year ago I read about the reduction of zinc dialkyl dithiophosphate (ZDDP) in the oils supplied with API approval that could affect sliding and high pressure (EP) friction in our cars.
The reduction of these chemicals in supplied oils was based on the fact that phosphates reduce the effectiveness and eventually damage catalytic converters and introduce minute amounts of pollutants into our atmosphere.
A couple of months ago I had a member of the Columbia Gorge MG Club bring a totally failed camshaft and lifters back to me that had only 900 miles on them!! I immediately contacted the camshaft re-grinder (Delta Cam) and asked how this could happen. They were well aware of this problem as they were starting to have many failures of this type.
In the past, the lack of a molybdenum disulfide camshaft assembly lubricant, at assembly, was about the only thing that could create this type of problem.
My customer has assembled many engines and had lubricated the camshaft properly. Then the bad news came out: It’s today’s “modern” API (American Petroleum Industry) approved oils that are killing our engines:
Meaning all flat tappet (cam follower) equipped engines, as used in all BMC products, all British Leyland products, most pushrod engines prior to 1980, early Volvos, American high-performance engines and many others, including Motor Cycles.
Next call: To a major camshaft supplier, both stock and performance (Crane). They now have an additive for whatever oil you are using during break-in(running in ) so that the camshaft and lifters won’t fail in an unreasonably short period of time. They also suggest using a diesel rated oil on flat tappet engines.
Next call: To a racing oil manufacturer that we use for the race cars (Red Line Oil). Their response: “We are well aware of the problem and we still use the correct amounts of those additives in our products”. They continued to tell me they are not producing API approved oils so they don’t have to test and comply. Their oils were NOT the “new, improved and approved” ones that destroy flat tappet engines! “We just build the best lubricants possible”. Sounds stupid, doesn’t it, New-Approved but inferior products, but it seems to be true for our cars.
To top this off: Our representative from a major supplier of performance and street engine parts (EPWI) stopped by to “warn us” of the problem of the NEW oils on flat tappet engines. This was a call that the representative was making only because of this problem to warn their engine builders!
“The reduction of the zinc, manganese and phosphates are causing very early destruction of cams and followers”. They are recommending that, for now at least, there must be a proper oil additive put in the first oil used on new engines, beyond the liberal use of molydisulfide assembly lube(Molybond).
They have been told that the first oil needs the additive but remain skeptical that the first oil is all that is necessary. Their suggestion is: Use diesel rated oils such as Delo or Rotella that are usually available at auto stores and gas stations.
This problem is BIG! American Engine Rebuilder’s Association (AERA) Bulletin #TB2333 directly addresses this problem. I had a short discussion with their engineer and he agreed with all that I had been finding.
Next phone call was to a retired engineer from Clevite, a major bearing and component manufacturer. First surprise was that he restored older British Motor bikes. The second surprise was that he was “VERY” aware of this problem because many of the old bikes had rectangular tappets that couldn’t rotate and are having a very large problem with the new oils. He has written an article for the British Bike community that verify all the “bad news” we have been finding.( I am looking for that article…Bob C.)
Comp Cams put out “#225 Tech Bulletin: Flat Tappet Camshafts”. They have both an assembly lube and an oil additive. The telling sentence in the bulletin was “While this additive was originally developed specifically for break-in protection, subsequent testing has proven the durability benefits of its long term use. This special blend of additives promotes proper break-in and protects against premature cam and lifter failure by replacing some of the beneficial ingredients that the oil companies have been required to remove from the “off-the–shelf oil”.
Next question: Now what do we do? From the camshaft re-grinders (DeltaCam) “Use oils rated for diesel use”, Delo (Standard Oil product) was named. About the same price as other quality petroleum based oils. They have the ZDDP we need in weights we are familiar with.
From one camshaft manufacturer (Crane): “use our additive” for the first 500 miles.
From General Motors (Chevrolet): add EOS, their oil fortifier, to your oil, it’s only an 8-ounce can (This problem seems to be something GM has known about for some time!). The additive says for break-in only, some dealers add it to every oil change.
From Redline Oil: Use our street formulated synthetics. They have what we need! Early in 2007 they will be supplying a “break-in oil” specifically for our cars.
From Castrol: We are beginning to see a pattern emerging on older cars. It may be advantageous to use a non-approved lubricant, such as oils that are Diesel rated, 4 Cycle Motorcycle oils and other specified diesel oils. They will be supplying “new oils” specifically for our cars in early 2007.
For you science buffs: ZDDP is a single polar molecule that is attracted to Iron based metals. The one polar end tends to “Stand” the molecule up on the metal surface that it is bonded to by heat and friction. This forms a sacrificial layer to protect the base metals of the cam and tappet from contacting each other. Only at very high pressures on a flat tappet cam is this necessary because the oil is squeezed/wiped from the surface. This high pressure is also present on the gudgeon pin (wrist pin) in diesel engines, therefore the need for ZDDP in all diesel engines.
Second part of the equation is Molybdenum disulfide (Moly). The moly bonds to the zinc adding an additional, very slippery, sacrificial layer to the metal. I found out that too much of the moly will create problems; lack of this material reduces the effectiveness of the ZDDP. The percentage, by weight is from .01 to .02%, not much, but necessary according to the chemists. ( Moly also bonds to other surfaces like crankshafts and camshafts giving greatly reduced friction)
Now there is no denying that there is a problem, lack of ZDDP (Zinc Dialkyl DithioPhosphate) in modern oils kills at least our cams and tappets. There seems to be no known alternative. Our cars are a small percentage of the total market and BIG Corporate, the American Petroleum Institute and possibly governments have made decisions that are detrimental to our cars. This problem isn’t going away.
The trend today is to lighter weight oils to decrease drag, which increases mileage. Most of these seem to be the “Energy Conservation” oils that we cannot (should not) use.
Redline oil and others are suggesting a 3,000-mile break-in for new engines! Proper seating of rings with today’s lubricants is taking that long to properly seal. Shifting to synthetics before that time will just burn a lot of oil and not run as well as hoped. The “Energy Conservation“ trend was first led by automakers to increase mileage numbers and secondly because the ZDDP and other chemicals degrade the catalytic converter after extended miles, increasing pollution. Most of us don’t have catalytic converters and the mileage gains are not that significant.
Many oil companies may have products that will continue to function well in our cars. Castrol, Redline, Valvoline, Mobil, Shell, Amsoil and others have now commented on my original article and are making suggestions. Some companies are offering short lists of “acceptable” oils, others just one. One company has responded without any substantive information in a two-page “bulletin”. By their account all their oils are superior and applicable. This is typical of many companies.
Some oil manufacturers are pointing to metallurgy, blaming poorly built cams and followers. This may have some validity but the bottom line is that there has been a big increase in failures with products that have been on the market for many years but are now having greatly increased failures. To me the bottom line is, if the lubricants are working there is no contact between surfaces, it shouldn’t matter what the materials used in the products are, within reason.
On “modern” production cars, stay with the manufacturers’ suggestions. For any car produced before about 1990 the owner needs to be aware that the factory suggested lubricant may have changed and may not be applicable. Flat tappet, stock, performance or modified may be affected. MGBs from 1975 to 1980 must choose to sacrifice the cam or the catalytic converter as an example of how difficult the decisions are becoming! Yes, there is more! Castrol does understand our dilemma and is actively looking into what it can do to support our cars. We can soon expect to see products from them with specific application to classic cars. Red Line will be offering a “break-in” oil soon after the first of the year. Shell’s Rotella will be good until about June or July of 2007 ?? with possibly nothing after that date. Delo (Chevron) will also be questionable after the new “CJ-4” standards come in the middle of 2007.
Now the important information: Oils that may be correct for our cars today: (As reported by manufacturers by 31st December 2006, NOTE: many have changed their recommendations over the last three months!
Castrol: Syntec 5W-40, Syntec 20W-50, Grand Prix 4-Stroke Motorcycle oil in 10W-40 and 20W-50, TWS Motorsport 10W-60*, BMW Long Life 5W-30* *= full synthetic, available only at BMW dealerships.
Red Line: 10W-30, 10W-40 (Synthetic oils)
Valvoline: VR-1 20W-50 (Conventional oil)
Amsoil: 20W-50(TRO), 10W-40(AMO), 15W-40(AME) & 20W-50(ARO)
Mobil: Mobil 1 5W-30 and 20W-50 (Synthetic) Chevron: Delo 400
Shell: Rotella
What we are doing at Foreign Parts Positively has been difficult to determine but with few options left, the following is what we are forced to do. Some of our choices have been based on the manufacturer’s willingness to help and specific reports. This list will change in the next months with Castrol and Red Line adding products just for our cars. Break in: Delo 400 30W (A break-in oil will be available from Redline soon!) Conventional oil: Valvoline VR-1 20W-50 Synthetic: Red Line 10W-30 in newer engines, 10W-40 on older engines. Break-in is now 3,000 miles (using Delo 400 30W) before changing to running oil. Oil change interval: 1 year or 18,000 miles with Red Line synthetic 1 year or 2,500 miles with conventional oil (Valvoline VR-1) 20W-50).
Thank you to Castrol, Redline, Christiansen Oil, Valvoline, Mobil, Shell, Standard Oil and Amsoil for input. We’re sure this subject will continue: Please forward any new information on this subject you may encounter.
We have received some very interesting material from “Mr Moly” that may be putting molybdenum disulfide (MoS) into this discussion. It seems that ZDDP plus MoS is the best from the oil companies’ opinion but MoS by itself may be beneficial. Some racers swear by it. The literature seems to support “Mr. Moly’s” position.
Update 20th February 2007: In North America Castrol will have a “Classic” 20w-50 Syntec on the market in April for us. Meantime Red Line Oil for synthetic and Valvoline VP-1 20w-50 for conventional seems our only choices.
