I know I was pushing it....the needle was on the E for waaay toooo long. I got home just fine. Got up in the morning to go to work......DAMN!! It would only run for about half a second and die.
To make a long story short, the Xfire took exactly 16.1 gallons to fill until the pump stopped on its own. Got in 16.25 gal before the pump would cut out from overfill.
I was 9 miles from getting to 400 miles. Calculating MPG: 391/16.25 = 24.06.
Not too bad!
FYI, I got about 20 miles out of it when the needle was actually on E.
