Probably being just a tight wod. Sometimes I even use 93 depending on the type of gas. I try not to get lower than an half of a tank to make it easier to switch back and forth. It just works for me. Taken it in for the first service. I have 16000 miles on it. Didn't want to put that many miles on the oil change. Wanted it serviced before I went on the trip with 13000 miles on it with 2 weeks of having it for a year and BMW wouldn't change it.
