Many drivers were shocked after discovering that they’d been wasting their time trying to save petrol.
One person said: “God, I’m a moron.”
Another said: “Oh my god, I’ve only ever had an electric car, so not something I’ve thought about, but my partner does this.
“I’m going to tell them to stop p***ing about now.”
A motors expert said that trying to get the last drops of fuel out of a petrol nozzle will often cost you more money.
David James, Fuel car expert and Sales Director at Right Fuel Card, told the Mirror: “Pumps are able to detect air pressure and will stop when they can sense that the tank is full.
“Any fuel pump after that point will likely end up on the ground through an overflow tube, so those few extra clicks will likely just be costing you a few extra pennies for nothing.
The expert shared some tips to reduce fuel consumption.
He said: “Check to see if your local supermarket is running a deal, and if so, get your shopping first to get your money off or extra points vouchers.
“It’s also worth looking out for deals with bank accounts. As well as getting a reward for switching, you can often get cashback for fuel purchases.
“Fuel expands in warmer weather, so less will fit in your tank.
“Don’t let your tank regularly get too low or run dry as this will likely cause bigger, more expensive problems with your engine.”
