What Happens if You Put Diesel in a Petrol Car?

If you have mistakenly put diesel in a petrol car then you will be relieved to know that usually there isn’t any serious damage caused to your engine.

However, if you try to drive your petrol car with diesel you could cause serious damage to your vehicle. This is because the diesel will be circulated around your petrol engine. Unlike diesel, which has to be compressed to ignite, petrol is ignited by a spark generated by the spark plugs and if the car is started the diesel will clog up the spark plugs and fuel system, causing the vehicle to misfire, smoke and possibly stop running.

After the contaminated fuel has been flushed from the system, the bike or car should start fairly quickly.

You will initially see smoke whilst the diesel residue is burnt off, after this the vehicle should run as before the incident. If you do put diesel in a petrol car, it’s important that you stay put and call for help.

Symptoms Of Putting Diesel In A Petrol Car

The Engine Won’t Start

After putting diesel in a petrol car the diesel will cover the spark plugs and make the engine difficult to start if it starts at all.

The Engine Misfires

If the car is driving after misfuelling the engine will begin to misfire after the spark plugs are clogged up with diesel.

Smoky Exhaust When Driving

The diesel in the petrol engine will cause excessive smoke to be produced from the exhaust while driving.

The Engine Cuts Out

After driving for a short time the engine will cut out and the car will break down and likely won’t start again.

What To Do If You Put Diesel In A Petrol Car

Haven’t Started The Vehicle

With any misfuelling when diesel is put in a petrol car we recommend a full fuel drain of your fuel tank. If you haven’t started your car then there shouldn’t be any damage caused to your vehicle. In addition, we recommend that if you have put any quantity of diesel in your petrol tank then you should use a specific additive to remove any diesel residue left in your fuel system.


Started The Engine

If you have started your car we recommend a full drain of the contaminated fuel and then flush the fuel lines with clean petrol. Once this has been done, you should not suffer any further problems to your car and should be able to fill your car with petrol and drive away without any further work needed.


Driven The Car Before Realising

If you have started your vehicle, STOP driving as soon as it is safe to do so. A full flush of the fuel lines and tank is essential to remove any contaminated fuel. Once this flush has been carried out and the vehicle has cleared the remaining residue diesel from the system, your car should run fine. We do recommend, as an extra precaution, that you change your fuel filter within a few days of the incident, these are a relatively low cost component and are simple to install.
