My low fuel light has been coming on when the trip meter says I have used 25 gallons of gas and the gas gauge reads about 1/8 of a tank. The miles to empty says about 40, but isn't counting down mile for mile as I drive.

When I have filled up, I have put in about the same amount as the trip meter says I have used.

I thought this truck was supposed to have a 35 gallon tank? There can't be 10 gallons of "reserve" can there?

I have only filled it up a few times since I only have 1000 miles. Is there some kind of self-calibration the system needs to go through with more use?

Is mine normal compared to the other trucks? I have a dealer appointment for Monday hoping they will find the computer is programmed for the wrong tank size or something like that.

Thanks,

Is there a real mechanical level sensor in the gas tank? What triggers the low fuel light on the dash?

Thanks,

I went to the dealer today with my trip computer saying 28 gallons used and 8 miles to empty. They plugged the computer in and confirmed the truck is setup for a 35 gallon tank and said my tank was 8% full which is 2.8 gallons remaining.

I filled it up and put in 31.6 gallons; the trip computer said 28.5 gallons used at that time so it was reading about 3 gallons short.

This tank was all city driving so maybe that throws the computer off some. I'll just have to get some miles on it and either it will learn my driving or I will learn how the system is going to work.

I would be very interested in the data from you running it dry. I ran mine on 0 miles to empty for 15 miles or so and put in ~34 gallons if I remember correctly. I generally fill up when the trip meter says ~30 gallons used and put in 32 or so.
