Not sure if this is the right section or not.

I believe the '98 LS1's have a 15.5 gallon tank. When I get down to E or just barely above it and go to fill up - I can fit about 12.8-13.1 gallons in it. Is this normal? Shouldn't I be able to fit atleast 14 in if it's that close to E and sometimes right on it?

So, the '98 F-Bodies are suppose to have 15.5 gallon tanks. When my needle gets down to a hair above E, I can fit right about 12 gallons in the tank. Is this normal?

I just started noticing it because I've been trying to figure out my MPG.

[EDIT] Going off of my ~210 miles to that tank I just filled up off of, I get ~17.5 MPG in the city with 12 gallons. [/EDIT]

I usually fill ~12 gallons when I'm at 1/8 of a tank. On my car, the light comes on when there is about 3 gallons left. I usually average 17-18 MPG. If I keep my foot out of it, I can get over 20.

I never seen the light come on, I should wait it out sometime and see when it does. I'm going to do that with this tank and hopefully I'm within 40 miles of a gas station when I see it.

I procrastinate, so I dont fill untill the light comes on, and at that point it takes about 14gal, the plastic tank holds 16.8.
