Do you fill up when the light turns on? I most cars, the light turn on when there's 1-2 gallons left in the tank. To me, 24-28 gallons doesn't really mean anything...it still ends up to be $70 to fill up.ftnssn said:I wouldn't say it's a problem, more a question. The owners man. says 28 gallons but when i fill up i've never been able to get more than 24. What gives?
