anything I can do or buy to improve gas mileage!

I freshened up the brake system and replaced calipers and rotors and was surprised to go from 15MPG to 17MPG hand-calc'd in my AWD v8...I freaking love the beast even more now!!

Yes if you have only slightly "dragging" brakes they can rob you of a few MPG, if you're used to driving it that way it is a surprised when you redo the brakes and they're no longer dragging and you see an increase in MPGs
