SBL, just an fyi, in a non flex vehicle you can top off with ethanol (e85) so lets say your tank is 60% full of gasoline your can top off with ethanol and gain some impressive performance and still keep your car's computer happy. I got a flex kit so I can burn any combination but topping off can really give you great performance in a non flex configuration. Interestingly, I noticed with e85 the exhaust smell is sweet instead of that toxic gasoline fume smell. Too bad they add gasoline to ethanol (to denature it) otherwise it would be 1 gallon for the car, and one gallon for me... (;
