A can of MoS2 is around $5.60 plus tax where I live, and I have a little stash of it. I don't know about running Ceratec in my M3, but so far I notice no ill effect with MoS2 and my car is not burning oil even though I occasionally rev my car to 8600RPM.

Try ceratec. Its like mos2 but uses ceramic nano particles or something. It last for 30000 miles between treatments too however I'm using it every second oil change. I've got a stash.

I would think the oil burning occurs pre operating temp no?



I'd run the M1 0w40 without hesitation.

Are you positive the oil is burning and it's not leaking?

Yes positive. Its garaged so I would spot if I was leaking, plus the smell is extremely distinct. I have been using the service warning as to when it's time to change. I'm not even sure what the intervals are between changes. My ignorance is kind of embarrassing. From what I have read it's very common to go 5k I think. A habit I'll probably adopt.

I did see some guys posting saying they were going through 1 qt every 2-3k. I'm doing a qt like every 6 months. Leonardo629 (another huge m3 poster) has me tempted to try that additive he's using.

The factory interval is 15k, or whenever the car tells you to change it.

Most guys opt to split the difference and change it every 7-8k. I would certainly keep an eye on that consumption. If it is consistently drinking that much oil you are probably okay, but if the rate is going up then you should be investigating.

Personally I think type of break-in has much to do with regards to oil consumption. Pity BMW doesn't do a break-in for the engine at the factory.

I didn't want to mention break-in procedures because it's a can of worm that needn't be opened.

I have been in the "hard" break-in camp since my younger motorcycle days, so of course I couldn't shake the old habit even when it comes to cars.

I really can't tell you if it's the MoS2 or my break-in method, but my S65 is not burning oil (I have around 4000mi accumulated on the M1 0W40, will change at @ 5000mi and an UOA).

High revving M motors are equipped with low tension piston rings according to a quote I read by a M engineer, so it's normal to burn some oil, did you check your oil cap? BMW oil caps do not seal for the amount we pay for these M cars.

BMW M engines have the 1200 mile break-in period. Special oil and redline is severely reduced. Most modern motors come broken-in anyway.

Not sure why there's an expectation that a car should burn zero oil. As long as it is drinking it at a reasonable and consistent rate, keep on driving it and enjoying it.

It is the opposite. 95-97% of engines aren't fired at the factory. They are only cold tested.

I oversimplified. Modern engines are built with very good tolerances and didn't have the variation you used to see 40+ years ago. The notion of break-in is not what it used to be.

I know for a fact that BMW does put all their cars on the dyno before they leave the factory.

+1, but they're not cycles under different loads from what I understand.

BMW's confusing and self-contradictory statements regarding oil for M motors comes down to two things;

1 - A way to wriggle out of repairs under warranty, chances are the car did not follow the reccomendations every time they were changed,

and

2 - The prevalence of the internet means that you guys in the US can pick up a TSB that was meant for the colds of Northern Europe (or some other geographical crossed lines leading to misinterpretation)

Bottom line?
Redline or Millers.

Well I'm even more confused now.

The dealer just performed the 1200 mile service on my M6.

I requested Castrol 0W-40 be used but the dealer advised that, indeed, BMW 5W-30 was the proper fill.

Owner's manual clearly states 0W-30 or 0w-40 is approved with 5W-30 and 5W-40 also being acceptable.

I plan to run the 5W-30 for 5000 miles and then change with Castrol 0W-40 myself.

Even with uber LL-01 Euro spec oil, I can't say I believe in BMW's 10K OCI for this vehicle.

It is not only BMW, all manufacturers are saving on oil since they are performing "free" oil changes (free means you will come later once carbon builds up etc).
Go check my UOA on M1 0W40. After 5K TBN was at 2.6!

If you read the links to the M3 discussion forum I posted, it is actually a matter of BMW NA making a different recommendation than BMW corporate. The memo saying LL01 is okay was only for North America. Everywhere else, you have to keep using TWS.

The manual probably says 0w30, 0w40, 5w30, and 5w40 are acceptable for top-ups. Mine says that.

10k might not be so bad, actually. Remember that the car has a huge sump and a large filter. There are a lot of M cars that did the 15k intervals without any major problems. Mine did.
