: Hi all,
: Can I use Premium Unleaded in my 90 535I? I belive the octane rating is about 98. Will this cause any problems? I am using regular unleaded now. I live in Australia so our fuels aint to good.

: Thanks

Use whatever octane rating it says to use in your owner's manual. It makes no sense to use a higher octane than called for, sometimes the car won't even run as well on higher.
