Klassic, so how many times do you bang into a door before you open it

 

Bluestang is right on that...I am speaking from my personal experience. when my 04 FX4 Screw light came on. I drove additional 3 miles and refilled it. My truck took approx. 23-25 gallons of gas/ approx. $50.00 (I think it was $49.97). So when the light comes on, you have approx. 5 gallons left.

 

I'm like Kramer in the Seinfeld episode when he drove around with the car dealer seeing how low they could get the gas needle to go....
I get a real adrenaline rush from it..
