Finally, some good news for the beleaguered British motorist!
It seems that inaccurate counters on petrol station pumps are giving drivers up to 4.4% more fuel than they paid for.
The AA tested a number of pumps after drivers complained that they were not dispensing enough petrol.
Weirdly, however, it turned out that many pumps are dispensing too much fuel, lowering the price of petrol by up to 6p per litre in some instances. Unfortunately, the AA has not released a list of the garages affected.
With petrol currently selling for 134.17p a litre (up from 116.0p in 2010), we can't help wishing that there were more defective pumps across the country.
BuyYourCar.co.uk's top tips on getting the most fuel for your money:
1. Fill up in the morning.
The petrol is stored underground, and in the morning the ground is cold. Petrol is denser when it's cold, so you get more for your money.
2. Fill up when your tank is half full.
If you wait for your tank to empty it will be full of air, making the fuel more likely to evaporate. Filling up when your tank is half full therefore means that less of the petrol you're putting in will get lost in the atmosphere.
3. Fill up slowly
All fuel pumps have a vapour return which sucks fuel vapour back into the underground tank for safety reasons. When you fill up quickly, more fuel is lost as vapour, and the petrol which you've already paid for goes straight back into the underground tank.
