ok I did another fill up earlier in the week before a road trip. 13.55 mpg. that was typical around town with some highway driving. after the road trip I still haven't filled up because I still haven't finished the first tank never mind gotten into the back tank. If the front ran empty on startup I'd still be at 13.66 mpg I did go back and have the rear brakes adjusted after a break in period so they are definitely tighter now. That may cost me some for awhile. I know there is a bunch of people on here horrified to hear this but I'm over joyed at 13.66 mpg. THat's a 21% increase. No mods/no real special driving style. I may make this 15 mpg yet
