Hi,
I'm going to be changing the oil in the 328i in a couple of weeks. I'm wondering what the best oil for it is? I'm reading conflicting reports on it.
So far from searching I've seen:
0W30
5W30
5W40
10W40
And also 10W60 which seems a bit too viscous, unnecessary and I wont be putting it in.
What oil do you use?
Castrol recommends 5W40 and I think I'll go with that, just want to make sure.
Thanks,
