How to avoid putting the wrong fuel in your car?
Like we said, many Brits fill up with the wrong fuel every year. When driving a petrol car for so long, then changing to a diesel this mistake can easily happen. Depending on the make and model of your car, you may be able to buy a diesel fuel cap for your fuel neck to stop petrol nozzles from fitting into fuel tanks they’re not meant for.
Some cars nowadays will also have green or black around their fuel neck, as well as stickers on the fuel cap to let you know what fuel the car requires.
