After getting back from out of town, I found that my 1990 525i was driving kind of sluggishly. Something just felt wrong with it. I had just changed the timing belt and all the drive belts the week before and was afraid that i may have screwed something up. When I went to the pump to fill up I realized that I had lent my car to my cousin without telling him it takes only premium. After calling him I found out that he has filled up with 87 octane gas. I have drive a full tank of this. Do I have anything to worry about? Could I have messed something up? After changing over to premium all was back to normal, but I am afraid I might have damaged my engine.
