Sorry for the typos but I am in pain for the past few weeks with a mild infection makes it hard to concentrate at my age. Ok so the mileage in my BMW R100S increased from 40mph to 60mpg because I changed the bearings and not from getting the tranny and rear end teflon impregnated. And I got 48.3mpg driving home last night in my 2006 Scion xB because I have excellent coasting skills and not from the Synlube in the engine, tranny and power steering and acetone in my gas tank.
