Does the E36 require premium fuel? If so, what happens if you use regular?

Yes, the e36 requires 91 octane, Premium fuel. If you use regular you lose power and could possibily damage your engine over time. To save 10 cents a gallon it is not worth it.

My e36 requires a minimum of 89. I use 91, but it requires 89 (mid-grade).

I have a L4, so I don't know about the L6 engines.

My owners manual for my 98 323 requires 89.
