Hi Everyone,

Which engine oil is better?

Castrol Syntec 5W-50 (not too sure if it's good for BMW engines)

Mobil 1 15W-50 (From the label, it says it's for high performance cars)


Can anyone tell me what's the difference between the 2 brands of oil and which one is suitable for BMW engine.

Thanks,

BMWBOY88

Oh come on,

This is like the third thread this week regarding oil.

Please do a search next time.

Anyhow, to answer one of your question, a large group of people
on this board will recommend the mobile 1 oil

Personally, I used mobile 1 0w40.

There is German Castrol and NorthAmerica Castrol, the German Castrol is OEM to what BMW dealers use.

Good luck!

Sergio, German Castrol is BMW Longlife approved, but BMW uses standard 5W30 castrol which is NA.

But to answer your question, I wouldn't touch 5W50. M1 0W40 is ideal, as is German Castrol 0W30.

It would be nice to be able to do a search for oil, but the board dosen't allow any searches with less than 3 letters....
