In Reply to: Oil type... posted by Bmer_boy on August 30, 2001 at 23:04:30:

heard good things about both Red Line and Royal Purple.


Ok, I just purchased a beautiful 1990 535i. It runs absolutley great and has only 101,650 miles. THe onlky concern I have is the oil type I should be using for the vehicle. I've heard once before that I should use 10W-40 in the summer and 10W-30 in the winter. Is this correct or am I completely wrong?

Thanks
