no what he is saying is if your on a performance site to make your car faster you really shouldnt worry so much about your MPG since you need more fuel to make more power regardless if you have a 2 stroke 1 cylinder RC car or a V12. And i get between 17 and 19mpg in my 315rwhp 3400lbs V8 mustang....pretty good i'd say...and i've even seen 26mpg going to NC and back.
