You fight the urge to fill up at the normal number of miles ~550. You want to see how your new mods are doing but you know you should wait an s set a record distance along with the record MPG
just have to trust that the gas gauge at 1/4 left and the scan-gauge at 55 MPG tank average and 550 miles means you are doing well
You do not ask if you can beat your longest tank of 622 miles but if you can break 700 miles, aim high, hit higher
