I filled my 01 Subaru outback with 93octane earlier today. I drove from the my brothers to my house, which is all hills and then a shot on the highway for about 30 mins. Filled it back up, and punched the numbers 33.9mpg! That car never got more than 23mpg on a good day on 87. I am sold on Premium now.

Also, I did not change my driving habits either. <img src="/forums/images/graemlins/butwiggle.gif" alt="" />
