with confidence. so I imagine if there is an oil related failure that BMW wont cover, Mobile /exxon would? anyone doing this?

from thier website:

Listed below are the oil viscosities that your vehicle manufacturer recommends for different temperature ranges, as well as the Mobil 1 motor oil that is suitable for your vehicle. You Chose The Following Vehicle:
Make: BMW (edit)
Model: M3 (E46) Coupe (edit)
Year: 2001 (edit)
Engine: L6-3246cc 3.2L DOHC (S54) (edit)

10W-60 All temps

Mobil does not carry that specific viscosity. While it is always wise to check with your vehicle's manufacturer, you can use Mobil 1® with SuperSyn™ 15W-50 with confidence.

Veedol, which is approved by BMW and Shell Helix (used by Ferrari). Only Castrol TWS is available in the US.

Sometimes their web info and/or help desk info precedes product.

M1 0W-40 was all over Europe for years. It just recently came directly to the U.S., without having to go to a Porsche dealer's parts department. WalMart was carrying it for a while, but stopped since sales volume was too low. Ditto, 0W-20 (for Honda's and Fords).

Each 10 points on the SAE viscosity index is about equal to 15 degrees F. So, running M1 15W-50 in your M3 would be like running running Castrol TWS but 15 degrees F hotter. I'd pass until/unless the M1 10W-60 gets here.

Since winter's coming, how about somebody up north ask their dealer what oil to use in cold weather. The manual says to ask your dealer. I suspect they'll say M1 0W-40, but don't put it in the manual because of their extensive F1 support from Castrol.

Only Castrol TWS Motorsport 10W-60 is approved for the S54 engine because of the expensive oil additives so any 10W-60 oil won't do.

Both the BMW approved TWS Motorsport and the new not approved Formula RS are 10W-60 oils but with different characteristics. The viscosity at 40°C and 100°C are the same since they both are SAE 10W-60. But other values as the pour point (-54°C vs -42°C), flash point (240°C vs 208°C) and total base number (8,6 vs 11,0) are very different.

release from lotus regarding the elise:

"These models have been tested in all climatic conditions likely to be encountered with Texaco Havoline Synthetic 5W/40 oil which offers advantages in ease of cranking, smooth cold running and fuel economy at low temperatures, in combination with good wear protection at elevated temperatures and at high engine speeds. <b>However, if a car is to be driven on track at maximum effort, or in conditions or a manner likely to result in very high oil temperatures being achieved, the engine oil should be changed for Castrol Formula RS 10W/60.</b>"http://members.roadfly.org/atyclb/bonoinelise.jpg

When I recently ordered a case of TWS from Turner Motor Sports, I received a case of 10W-60 RS Racing Syntec. All the text on the container is in German except for a Castrol label with the BMW part number 07 51 0 009 420 which is the same as the TWS. Is Turner wrong in assuming that RS = TWS? If RS is not BMW approved, why is Castrol using the same BMW part number?

Some more info. I've talked to BMW M and Castrol about this and I've also seen the oil specifications.

To cut a very long story short BMW started to use the BMW High Performance Synthetic 5W-30 oil in the the S54 engine but then they changed this recommendation in June 2001 to the Castrol TWS Motorsport 10W-60 for "better behaviour under extreme conditions".

But the Castrol TWS Motorsport 10W-60 engine oil was not available on all markets at that time (i.e. the US) so that's why the old Castrol Formula RS 10W-60 oil also is approved.

The old Formula RS 10W-60 and the new TWS Motorsport 10W-60 are not exactly the same engine oils as stated. They have a slightly different formula and TWS Motorsport 10W-60 is specially made for BMW.

Yes BMW has used the same internally part number for both the old Formula RS 10W-60 and the new TWS Motorsport 10W-60 engine oils.

But then it becomes really confusing when Castrol decided to use the old Formula RS brand name for a new developed series of engine oils. And this new Castrol Formula RS 10W-60 is not approved for use in the S54 engine.

All these three Castrol engine oils (the old and new Formula RS and the TWS Motorsport) is using similar base oils but different oil additives for slightly different characteristics.

So for now the Castrol TWS Motorsport 10W-60 is the only approved engine oil for the E46 M3.

Mobil has listed the manufacturers requirements for pretty much all cars on the planet.

In the case of the M3, the maker insists on 10w60, and this is what Mobil reports.

Mobil does not sell a 10w60 in the US at the present time.

Thus a normal, rational person would come to the conclusion that you can't use Mobil oil in the car and expect any kind of warranty support.

I have no idea where this fantasy about using 15w50 in an M3 and suddenly Mobil will step up and replace your engine if it dies came from.

Until the final mile of my factory warranty, nothing but Castrol 10w60 will ever go in my crankcase. Period. Done.

by the BMW dealers to invoice oil when they tap the oil from 60 litres barrels.

Thanks for the information. I have the TIS disc, but never checked about the oil. I changed my oil with the old RS formulation about 1K miles ago and hope it will last another 2K until I take the car in for Inspection I and the bearing SA. I emailed Turner Motor Sports about the substitution. Since they have a picture of TWS and sent RS, I qustioned their honesty.

Chuck,

We sent you what BMW was selling at the time. I offered to replace any unused oil you may still have. Offer still stands, even after the litigious threats you have been emailing and calling me with.

For the last 50k miles i have used mobile 1 15-50w synthetic ...the 15k mile brand, or the most expensive bottle. Then i add 1 qt of lucas oil stabilizer syn blend. My car runs like a kitten on this. The oil stays cleaner longer. One time it went to the dealer for gbox and diffy oil change...well they did the engine too. The engine sounded harsher...but i drove it for 3k then drained it...oil was very dark.
Then back to m1/lucas...wow!!! Hwy driving at 4k and the engine noise is in pure harmonics and wants to pull and rev solid.

This has worked well in florida where its warm. I cant answer for cold climate performance

also desperate for a oil change ?...feeling guilty ?...just top up with lucas before the long trip...it will get you there and back with no harm to the engine

the e46 m3 is a tight tolerance engine...lucas is your warranty!

P.s the more you change oil the better it revs...every 3-5k!!!, and make sure the lucas is the syn blend. Don't run the oil level low on the stick...some times the oil warning light wont show when it should...again thanks lucas!

Here it is right from the horse's mouth (BMW USA):

http://www.bmwusa.com/Standard/Content/Owner/SyntheticEngineOils.aspx

Pennzoil is now owned by Shell Oil (as is Quaker State). They're marketing their European Shell Helix synthetic line in the states as Penzoil Ultra. The ultra line includes a 10W-60, which is used by U.S. Ferrari dealerships. Pennzoil's website sucks, and doesn't confirm the existance of Ultra 10W-60, much less telling you where to get the stuff.

Castrol is owned by BP, so if/when BMW approves Pennzoil Ultra 10W-60, I'll be switching as a matter of principle. (Gulf of Mexicco spill, lobbying for Scottland freeing the Lockerbie bomber, low quality gas (see www.toptiergas.com), and those whiney adds about green energy, etc., etc., etc.).
