    Gladiator Fuel Gauge Inaccurate

    This isn't a huge deal to me but wondering if anyone else has experienced this. So I filled up a few weeks ago when my fuel gauge was reading about 1/4 full and I only got 12 gallons. Then today, the gauge was almost on empty and when I filled up, I got about 16 gallons

    Thought this was a 22 gallon tank.....

    I honestly don't think I've ever put more than 18 gallons in my JL and that is with the gauge reading single digit miles to empty. One of these days I'm going to drive it until it runs out of gas to see what the safety margin in these really is....

    Working in dealerships, I've never discovered a fuel gauge or 'miles to empty' display to be completely accurate, but normally they're fairly close. This one seems way off. No big deal really just thought I'd bring it up here.

    Same for me. You can take all the way down to when it says low and won’t even tell mileage and still only put in 18 gallons.

    My Duramax has a 28 gallon tank & reads empty at 20 gallons,
    JL has a 21.5 gallon tank & reads empty at 15-16 gallons,
    Hybrid Rav4 from work has a 14.5 gallon tank & read well past empty when I put 11.5 gallons in it.

    Wife's Yukon XL Denali has 31 gallon tank & reads empty at 29-30... I prefer this to the way exaggerated empty readings in everything else.
