Okay i have really bad gas milage on my car. I get anywhere from 150-160 miles per tank. Sometimes more, but never anymore than 200. I will admit i do get on it occasionally but its not all the time. If that is the case and i just have a heavy foot then fine but i was curious if there was anything that i could check/replace that could help my car to be more fuel efficient. I know thats a stupid question driving a mustang and a V8 but hey if there is even the slightest room for improvement i'm m ore than interested in hearing about it.
