Hey guys,
Picked up the new addition and as a rule always change all fluids
first,no matter what the previous owner says - for my record.
Can you tell me what Brand oil I should get and numbers(weight and volume) to go with as far as the Engine Tranny and Diff go? Also what filter.
On my Supra I use Mobil 1 syntethic only!!
I'm sure the Bmw has a similar preference
Thanks

haha oil pump working overtime lol. 10w40 is a pretty good solution for the summer and so is the 15w50 as stated above. If it's a daily driver i wouldn't recommend the 15w50 in the winter.

M42 calls for 15w50 winter 20w50 summer, 15w50 synthetic doesn't thicken until -40c its fine to run all winter
