Technical Guides for the BMW Z Series
Hi all, so im on vacation in Spain and my 2004 Z4 with 200+km needed some oil (again).
Have to say that it uses a lot, common problem i understood.
I could only get 10W40 and 5W30, the old oil was a 0W30. I chose the 10W40.:eek
Would you recommend to have the oil changed at a garage or is this...
