2001 e39 M5 - FBMWSH - What oil do they use?

[mikey-r]

Hi,

As above really, my new car's got FBMWSH and I need to top up the oil.... what oil would already be in there. I've just got some CASTROL EGDE 0W-30 (has "For Modern Engines, BMW Longlife-01" on it) but haven't put it in yet.

Cheers.

For the M engined BMW's you need to be using Castrol Edge 10W60. Not Edge Sport, just plain Edge. It's specifically for M engines and is what people should use. That's not to say that other oil is worse, or even better, it's simply the preferred oil for an M

Thanks for the quick reply Matt. I know there's quite a few different recommendations which I hope to research in the next few weeks. What I'm after at the moment is just to top up with whatever is in there.

Just looked on the OPIE website and they also recommend the Edge 0W-30 - I'm assuming that's what they're told to recommend by BMW - what do you think?

There's been a bit of debate over this.

Apparantly early E39 M5s should use Castrol Edge 10W60(It was originally Castrol TWS Motorsport, but this is no longer available).

Later cars, from about March 2000 onwards with the modified piston ring design, should use Castrol Edge 0W30.

To be honest, I doubt that it will make much difference either way.

I'd go for the 10W60 - its just better.

Thanks for the links and advice.... I'll get reading!

I understood the oil you choose can also be affected by the temperatures you run it at. If you do loads of short journeys, and therefore lower temps, then a lower vicsocity oil would be better (0W-30), but if you are on long blats everywhere, use the 10W60. I have TWS in mine at the mo. but might shove some ought-thirty in over winter...

I was using the Castrol TWS in my 2002 M5, but after a recent service the dealer switched to Mobil 1 0W-40. It's been running fine and using less oil than previously. Opie Oils also back this up as a recommended oil for all revised M5s.
