Gas mileage 1998 mustang

Answer 1

You might need to explain what you are asking. If you want to know what the average mileage should be - consider that most waranties are good for five years or 50,000 miles. That means a car could be driven around 10,000 miles per year. Your car could have been driven more or less. Maybe, if you state the mileage on it, someone could tell you whether it's a good number or not.
