I bought a 2003 Honda Accord this past summer its a 4 cylinder coupe with approx 230000 km and during the fall months i was only getting about 480 km before the gas light goes on and thats with mix highway and city driving and i usually drive the car no more than 110 km/hr on the highway. My friend purchased the same car, same year with 200000km on it. His car gives him about 540km before the light goes on and he drives his car 120-130km on the highway also with mix highway and city driving. I recently did a tuneup where i changed all 4 spark plugs and i also changed the filter. I was thinking of resetting the car to factory settings by removing the battery terminals.
Is there anything else i can do?
Added (1). Also both cars are the same year, automatic, same trim (probably doesn't make a difference) and his just has 30,000km less than me. We also calculated that if i fill up with 54L of gas ill have only driven 480km and if he fills up and puts in 54L of gas his odometer reading is at 570km
