Fuel tank question

[jdrew]

I have noticed that if I fill my tank with it at 1/2, that it will only take about 6 or 7 gal to fill.. isn't it a 23 gallon tank? Shouldn't that number be a little higher, like 10-12 gal to fill?

I have also noticed that in both of my h3's that if you fill it to the top, you will only get about 30-40 miles before the gauge shows it back to the F on the gauge.. In the wifes jeep and my other cars I have known, if you top them off, you can get 50-75 miles before the needle gets past the F mark...

Anyone else notice this? Or am I in a very unique situation..

Secondly, is there a low fuel warning of some sort? I never let it get that low to find out.. But I may just to see how much it will take..

Thanks for the replies!
