Yeh... could just be a coincidence on the mileage, but I'll stick with it and see... with my luck if I pour some directly in the chamber I'll blow it up... lol I'm gonna play with the octane thing a little more, but I can swear it starts quicker on 87...... I suppose brands come into play as well... I usually fill up at Arco, but that last tank I got 36 mpg on, I had filled up at Shell! Who knows?
