Changing fuel costs mean road users can never predict how long to hold a pump open to get the right price for their budget. Cash-strapped motorists often want to just top up their car with just a £10 or £20 limit but costs can often rise as you lose track of spending.
It has led to several motorists accidentally overfilling their car by a few pennies here and there.
For most people, modern technology means a little bit extra can be paid on a bank card in seconds.
But for motorists without access to a bank card or those only carrying loose change, this could prove to be an issue.
However, many drivers are unaware it is possible to set a limit on how much fuel goes into your car directly at the petrol station.

This will stop the fuel pump from releasing petrol or diesel when the limit is reached in an ingenious way to prevent small slip-ups.
Motorists need to press the 10 and/or the 1 key on the petrol station keypad to set their limit to the amount they want.
Road users can also determine whether they want to set a limit based on fuel cost or litres in a major win for motorists.
The tool means road users will never fall foul of accidentally paying more than they should at the petrol station.
However, the litres option may also mean road users can work out how much fuel they would need for a journey and then put this exact amount in their tank.

This could reduce the number of stops you make and can reduce the overall journey time spent filling up a tank elsewhere.
It could also save money as motorists can fill up at a cheaper petrol station rather than being caught out somewhere with higher costs later on in their trip.
The advice was shared online with road users revealing details about the simple trick on social media platforms such as Twitter.
One road user confirmed online the service was in operation at pay at pump stations at Tesco.
Claire Fullick said: “I was today years old when I found out you can preset how much you want to spend at a petrol pump instead of trying not to go over that penny.”
Accompanied was a small image of the petrol station which informed motorists they could input a set limit before they began to top up their car.
The sticker read: “Don’t spend a penny. Before you lift the nozzle, tell the pump exactly how much you want to put in and it will stop it for you.”
However, the ingenious invention is not available at all petrol stations so motorists may still need to watch those pennies from time to time.
To avoid paying more for fuel, road users should keep an eye on the running total at all times and gently release their grip on the handle when it approaches their limit.
The RAC has confirmed fuel pump prices in the Uk did increase in January, despite supermarkets slashing costs oil a price war as the month came to a close.
On average, the price of petrol and diesel increased by around one penny per litre despite wholesale oil prices falling by up to 7p per litre.
Cost reductions were made at the end of the month and these have been continued into February as part of a three-way fuel war between Asda, Morrisons and Sainsbury’s
But the RAC claimed more should be done to reduce prices before revealing petrol and diesel costs were still too expensive.
RAC fuel spokesman Simon Williams said: “We strongly urge retailers of all sizes to play fair with drivers and cut their forecourt prices.
“Going forward we call on them to charge prices that more closely mirror drops in the cost they buy fuel in at in the same way they do when prices go up.
“Sadly, however, drivers are at the mercy of fuel retailers and this generally means they lose out on getting a fair deal.”
