Gas Mileage

[GreenNirvana101]

All of my guages must be off because I had my low fuel light come on on the DIC and my regular gas gauge said I was below 1/8 tank and when I filled it up I put in ~13 gallons.

Same here in my 1997 GTP.... I get to about 250 miles and then my low fuel light and DIC come on at the same time. I fill it up, but it stops at about 13 gallons?

Whats up with that?

The low fuel on the DIC comes on when it figures there are I think 60 miles left on the tank. And the low fuel light on the dash comes on at 1/8 of a tank left. And I usually go another 50 or so miles before I get gas, and put 13-14 gallons in it. I have never run out, but the most I have probably ever filled is 16.5 gallons or so. Maybe 17. But I don't try to push it too far.

None the less, it is not good for your fuel pump to try to get every little bit of gas out of your tank. For one, the lower the fuel gets in the tank, the more dirt is picked up by the pump. Sure, there is a screen, but that will get clogged and cause poor performance and possibly damage the pump. Also, the fuel in the tank is designed to keep the fuel pump cool. If you continually run your fuel tank as low as you can, you run the risk of overheating the fuel pump and causing a failure. It happens to a lot of people that try to do this.

So even though it may seem weird, I just try to fill up my car soon after the low fuel warning shows on my DIC. And yes, that is usually around 13-14 gallons.

I get about 22-23MPG city and 30-31MPG on the highway. I've hit 450 miles to a tank before I decided "stop now or stop before the next station".
