fuel

Was wondering if using 89 octane for my M54 would not be a good idea. For octane in my area the choices ar 87,89,93. The manual say 91 which is rare in my area

If the manual says 91, use 91 or higher. My manual says to use 89 octane or higher. I use 91 though. Most people use 91 octane in their cars. If you only have 93 then that will be fine too.

about fuel choseing fuel

I have a 91 525I and I put 93 in it. I found that if I put a lower grade in it I lost fuel economy.but since the 93 has more carbon when burnt I use lucas fuel injector cleaner its about $10 a bottle but u put it in every time u fill up and it keeps everything clean.
