What Happens If You Put Petrol in a Diesel Vehicle?

Diesel engines rely on fuel for lubrication. When petrol enters a diesel system, it acts as a solvent, stripping away this lubrication. This leads to increased friction and metal-on-metal contact and can result in:

Even small amounts of petrol can compromise your diesel system, especially in modern vehicles with high-pressure injection systems. Acting quickly is the best way to prevent damage.

There is severe wear occurring in the fuel pumps and injectors.

Engine stalling or failure

Internal corrosion in the fuel system

Costly repairs or even full engine replacement

Petrol in Diesel? What You Should Do Immediately

Diesel engines rely on fuel for lubrication. Unleaded petrol, on the other hand, acts as a solvent and can strip away this essential lubrication. Once petrol gets into a diesel engine system, it causes increased friction and potential damage to critical components, such as:

Do Not Start the Engine

Starting the vehicle circulates the contaminated fuel, increasing the risk of expensive damage. Even turning the key to the first position can activate the fuel pump.

Move the vehicle safely.

If you realise your mistake at the fuel station, place the car in neutral and push it to a safe spot with help if necessary. Avoid inserting the key or switching on the ignition.
