4130Higher Octane Issues

      Hello all!

      I recentley put 89 octane(US) in my 528e when I normally use 87 octane
      (US). I noticed that my idle dropped from around 900 rpm to around
      650. It kind of feels like it wants to shut off. It is a kind of
      sputter.

      Since I filled the car up with 89 I am just waiting to refill it with
      87 to see if it makes a difference. But does anyone have any ideas if
      higher octane gas can cause this.

      Thanks!
      Mark (1986 528e)
