: : What's the proper octane to use in a 95 540? The dealer I bought it from said to use mid grade (90) but I've seen a lot of talk on here about using super or 92. I just want to make sure I'm using the right stuff. Also, does anybody use Techron? I used to use it in my 635 a few times a year. Haven't seen anybody talk about it here though. Thanks

: My wife's '95 740i calls out AKI 89.

The owner's manual for my 540i says to use 89, that you can use 87, but may experience diminished performance.
