I have a 22' sport 1.5.. everytime I fill my tank it only shows about 340-350 miles. On my 19" I had, it would show up to 420 miles. Anyone know a reason for this and is there a way to rectify this problem ?
I've never paid much attention to this on my car but wondering if it is something that the car learns over time. It will take in driving style(s) & conditions and then adjust accordingly.
it calculates how many miles to a tank from the overall MPG. it just multiplies that number by how many gallons you have. resetting your mpg counter some easy driving should do the trick.
