so i went to fill up cause i was running on E so i got the sticker shock of teh fuel then i figured up my milage and i was getting 21 mgh adn the thing is i have been stomping on it like no other. black soot around every corner and stop light. adn i also beat a powerstroke this morning also. i wonder what i would get if i would go easy on her? what do you guys get for mpg when your towing or havin fun?
