I was surprised when filling my tank after the fuel gague went down to zero that after 15 miles of trying to find a gas station off route that i was only able to pump 10.8 gallons until the 'first click'. That leaves me with approx 1.5 gallons in the tank or 70 miles based on my real time fuel consumption. Does anyone know how much more capacity after the 'first click' the tank has - 1/4gal? 1/2 Gal? It seems pretty alarming to be driving with the car showing empty when i can drive that far a distance.
