Question about 1991 BMW 5 Series
I just purchased a great running 1991 BMW 535i. Is is best for this engine to have a 93 octane gasoline or can it work well with an 89?
Are there possiblities of creating problems if I use an 89 otctane?
Your expertise is greatly appreciated.
I have the owners manual and I thought it said Premium on all EXCEPT the i. I will double check tonight and post back tomorrow.
