is on the red at the r and the light is on it. after putting fuel in it goes
up to 1/2 tank i know the tank capitcay is 15gal ,full i dont know if the gauge is going bad or
what.last week i ran gauge down til light came on. i then put 20 dollars in drove it 4 days
no faster than 65mph i mostly drive interstate to work about 28 one way . i like to baby the gas pedal using the mpg gauge on speedometer for the best mpg possible car is a 2.5 with 5 speed.gas here in alabama is about 2.87 gal so does any one thinkthe gauge is right or what
any help would be great. thanks stovebolt

do you have the offset fuel gauge? i have one (and a 12gal tank) and from about the start of the redline ten bucks gets me a half tank and lasts about 60 miles ish. but thats city driving with a mix of quick quarter miles and "grandma" driving
