When the light comes on it usually reads about 40~44 miles to empty. The tank nominally holds 5.2 gal.... I once put in 5.1 gal with the miles to go odo saying I had 12 miles left to empty. Either I over filled the tank by a lot or the miles to go was over estimating.
OP has an adventure, 8.7 gallon tank.
