Hi all,
My friend is out of the country now and I need to do an oil change on his 1995 M3. Does anyone know what type of oil is recommended? Btw, I'd be using Mobile 1 synthetic.

i just did my oil change too. I used mobil 1 10w-30 i think it was full synthetic. Make sure is full synthetic. I think bmw recommends 5w-40.

You can use:

Mobil 1 10W-30

Mobil 1 0W-40

BMW 5W-30 - nice full synthetic oil, meets all BMW specs and is reasonably priced.

Also Castrol Syntec will be fine.

Yes, deinfately use full synthetic oils.

I have used Mobil 1 synthetic the entire 2 years of my M ownership. Great stuff! I used 0w40 for the first year, and am currently using 15w50 instead. Their are arguments to both weights. Definitely do not use Mobil 1 5w30- it's not the same as BMW synthetic, the Mobil 1 varient is too thin.

5W-30 is 5W-30. Doesn't matter whose.

The Mobil 1 5W-30 does not meet ACEA A3/B3 specs which BMW specs for the current cars. But that is only a serious consideration if youa re under warranty.

15W-50 is way to thick for a full synthetic on a street car.

You should search for a huge oil thread at bf.c- we covered this extensively. 5w30 may be 5w30, but Mobil 1's 5w30 does not meet the required standards for our cars.

I dont think 15w50 is too thick if you live in a hot area. I use it on ///m with no problems.

And how much hotter do you think your engine runs than ones in colder areas? The operating temps are pretty much the same. And why would not want better oiling faster at startup?

And I did say that Mobil 1 5W-30 does not meet ACEA A3/B3 specs, but for a car out of warranty, it is a fine oil, with a very good reputation. BTW the highly touted Redline oils are not even tested to ACEA standards.
