It's reported the tank size is 17 gallons yet when I fill up it's in the 14 range? My last fill was 14.3 and that was after driving it to 3 miles left according to the trip computer.

I've seen other threads on this topic but can't find a clear answer. Thanks

 

There's always a reserve of 2-3 gallons after you've reached "0 miles left" in every modern car.

 

Well that I'm aware of but I assumed the trip computer was including the reserve but guess I was wrong. Thanks bro
