How much do you trust the accuracy of gas pumps?

You look on the pump and it tells you gas delivered to the 0.001 gallons. Do you really believe that they are distributing gas to an accuracy of 0.128 oz?
I'm sure it's pretty close, but the amount of volume they do likely leads to so much theft that is questioned by nobody.

I always lift the hose to make sure I get everything I paid for.

Enough to make me never bother with whatever cumbersome effort it would take to disprove it.

“gasoline pumps must meet an accuracy standard generally between ±0.3% (acceptance) and ±0.5% (maintenance), as mandated by NIST and enforced by state agencies, ensuring reliable fuel measurement for consumers.”

And when you're trying to top off at an even dollar amount, they always get that extra penny.

Every time.
So I just keep going up to the next dollar, and if it starts spilling out, it just starts spilling out, but i want my receipt to show $x.00 so we keep going.

Because the states don't have any skin in the game with all the taxes that are added on to gasoline purchases, right?

They have little sticker that indicate they are spot on. I believe it without question. I have an EV though.

don't know about that, but I saw a sticker on a pump recently that said it was a federal crime to pump less than 4 gallons (or something to that effect).
don't ever remember seeing that on any other pump anywhere in my life.
why would that even be a crime?

I cited an NIST standard.
Per search, some states like North Carolina and Washington have notably high pump rejection or miscalibration rates in recent inspections. Human error or deliberate - you can decide.

Might as well ask do you trust the accuracy of a gallon of milk.
Really don’t understand the OT fascination on gas and gas prices.

Meh. When I overfill my 5 gallon gas cans they seem pretty accurate.
Posted on 10/21/25 at 8:15 am to Rouge
You can test it by getting a 1 gallon red gas can, and filling it up to see if it's accurate or not.

Not very much at all.
Sometimes I'll fill up and it will be 16.5-17 gallons. Sometimes it will be over 18. Makes no sense, and I'm sure gas station owners like stout are skimming off their customers all over the place.

i trust them because they send guys out in really cool hats to measure the accuracy of the pumps.

Andy Rooney did a piece where he asked for exactly one gallon of gas.
If the price was 1.59 and 9/10 (the price always adds 9/10), and they asked him for $1.60, he'd say something like, "No, that's too much. The price is only $1.59 and 9/10. I'll need some change."

Used to run convenience stores. Guy shows up every so often in a state ag (iirc) truck that has tubes and such. He goes to each pump and measure and dumps the gas back in the underground storage tank. He brings all the receipts back inside. Same dept iirc that tests the scanners and pricing.

Have never heard that in my life
I fill up a 2 gallon tank with ethanol free for my 2 stroke yard stuff all the time

Except the state department of Agriculture or similar supposedly tests them. OT rich shouldn't care anyway, do you not fill your tank until the vapor safety causes it to stop filling?
