Why won't my tank fill up?

[dagwood2001]

My local Food City will limit you to 20 gal if your using their value card and are using what they call fuel bucks, it’s a .15 cent per gallon discount for spending so much with the store.

 

Giant goes up to, I believe, $1.70 max off. I filled up for .30 cents per once, a couple years ago when gas was under 2 bucks....

Are you using a rewards card? Shell has/had a deal with Winn-Dixie for fuel savings at their stations here in Florida. Purchase was limited to 20 gallons.

That was my thought too.

After fill-up, go to the Onstar app on your phone and query vehicle status. It'll show how many gallons you have if you update it.

Admittedly new to the truck game, but I have a '17 Sierra Denali and no matter how much gas I need, it will never fill past 20 gallons. It stops it at the pump and I end up leaving with less than a full tank.

 

What's the purpose of this and how do I get it to fill up completely?

.02 Problem is either the fill station or the truck. If it does the same thing at a different station it is the truck. Try to fill with additional gas manually after a click off until you are sure the tank is really full and then check the gauge. If the gauge reads full, it is your filling procedure or a screwed up baffle in the tank......if less than full a bad gas tank sending unit.

Interesting... Never heard of a fuel limit by gallon. We have some stations here where there's a $100 limit to fuel up, but you just have to insert your card again and keep going.

We have stations that limit by both dollar amount or volume...it's a pain when you have a large tank to fill. And a lot of times, the card readers are set to only allow you to run your card once during a predetermined time (e.g., swipe once every half hour) that caused further frustrations.

 

20 gallons would be around $60, so that pretty typical...they are usually set for a max of $75 or $100 around here.

Update - filled up yesterday just left the pump on auto click. It filled the tank full. I believe what many have said in the thread is true - we hit the fuel station limit

Some gas stations will let you go over their pre-determined limit if you go to the attendant and ask him before pumping.Having a 42 gallon tank I've done this many times when it's very low.

I suppose there's an OUTSIDE chance that your sending unit is out of wack.

 

I had an '05 explorer that had the sending unit go wacko after I shot some Techron through it. Eventually corrected itself but had the sending unit swapped under warranty anyhow.

 

Just a thought.

Thanks for the update @demar002!
