What should I do if I put the wrong fuel in my car?

Around 150,000 people accidentally put the wrong fuel in their motor every year, according to the RAC, with it causing vital car parts to seize up.

If you do make the common mistake, it’s important to act quickly before the fuel passes into the car.

The most important thing to remember is not to switch on your vehicle, as turning on the ignition will pump the incorrect fuel through the engine.

You must then get the car towed to a garage, where mechanics will empty the tank and likely fill it with enough fuel to get to the petrol station.

What should I do if I have switched the engine on?

According to the RAC, if you’ve switched your engine on you should first turn off the engine immediately if it’s safe to do so. If not, pull over to a safe spot.

Then put the vehicle in neutral and call breakdown cover or a misfuelling service such as RAC Fuel Patrol to drain and flush your fuel system.

It also recommends calling your insurance provider as soon as possible.

Does this invalidate my insurance?

Many insurance companies will often refuse to pay out for any damage caused by filling your motor with the wrong fuel.

Figures from Defaqto revealed almost 60 per cent of car insurance policies exclude repairs for putting the incorrect petrol in your tank.

Other insurers may cover the mistake under accidental damage, but you will need to carefully read over the clause to find out the finer details.

Drivers can also be hit with a £5,000 fine for letting their car run out of fuel.

Can I drive my car after putting in the wrong fuel?

Michael Powell consumer motor expert at Defaqto said: “It is easy to put the wrong fuel in your car by mistake, particularly if you are driving one that you’re not used to.

“If you realise that you’ve put the wrong fuel in, do not start your car’s engine but do try and move the car to a safe place.

“If the engine is started, the incorrect fuel will enter the fuel system and potentially cause serious damage.

“This mistake can cost you dearly if you’re not covered for the damage caused.”
