So the past few tanks I've been filling up when it says anywhere from 2-10 miles to empty. When I filled up this evening it was indicating 2 mile range left. Just like the last few fill ups I put int 13.5 gallons. Does this mean there are almost 2 more gallons left in the tank that the miles to go indicator is ignoring (I have the Reserve so it's a 15.3 gallon tank)? If that's the case I'm guessing when it says 0 we probably have at least another 20-30 miles to go before it's really empty. I honestly thought that the tank was only 13.5 gallons because that's about what I've been filling up with the whole time.
yes, it's a safety measure so people don't wait until the last drop to refuel
