Well, I started to run 93 a couple months ago, partly because of what some of you said. The car does seem to run a little better, get slightly better mileage. However, there are some other possible reasons for this:
1. The car still has only 3,500 miles so still may be breaking in.
2. It's all in my head
3. The mileage increase is shown on the OBC, but I have been overall driving a little more "civilized."
