These are the average points at which the tanks are filled at E at the specified gallons above. The '01 is the most accurate, the 92 still has over 5 gallons on E. The '01 is easily the most powerful and the heaviest, yet gets the best milage on average.
The 97 AT gets into the 31-33 MPG range on long trips, it matches its MPG ratings pretty closely, the '01 exceeds its ratings and the 92' is well below its ratings.
The lights work on all three, but the 92's rarely comes on.
