Ex tank size

I know technically the tank is supposed to be 44 gallons, but how much of that is usable? I just got myself an 02 Excursion and am wondering how low I can run before filling up. Last fill up I got 37 gallons in and the gauge was halfway between empty and a quarter full.

Re: Ex tank size

Re: Ex tank size

I consider my tank empty when i get to the half way mark, this way I always have enough fuel for an emergency, it also limits the amount of air that can be leaked into the oring at the fuel mixing valve

Re: Ex tank size

I also rarely let my tank drop much below half. I like have several hundred miles worth of fuel available for any emergency.
Plus, don't run your tank to empty. Let any modern electric fuel pump run dry, even for a few seconds can cause some pretty harsh damage.

Re: Ex tank size

I ran out one car length from the fuel pump once. I got used to the fuel indicator vs reality and usually ran it down so I would put in 40 gallons at a time.

Re: Ex tank size

The most I have ever put in was 44.013 gallons, after 774.3 miles. My best range was 832.3 miles on a single tank and it took 43.553 gallons to fill up after that. I have never run it dry but obviously I have been close. I have found that the "miles to go" calculation on the overhead display gets very iffy when down below 100 miles to go. It decreases faster than the distance traveled. I have found that when it says 100 miles, I really have less than 50 so I start looking for fuel. By the way, if anyone cares the 832 was on soy based B5 fuel.
