Petrol in a Diesel Car?
We Fix It On the Spot

Accidentally putting petrol in a diesel car is more common than most people think and one of the most stressful moments you can have at a petrol station. The most important thing to do right now is do not start the engine. In a petrol in diesel situation, petrol acts as a solvent rather than a lubricant, stripping the protective coating inside your high-pressure diesel fuel pump and injectors. Even a small quantity can cause serious damage once the engine is running. The faster you call us, the better your outcome and in most cases where the engine has not been started, a professional fuel drain and flush is all that is needed to get you back on the road.

Put petrol in a diesel car? Do not start your vehicle

Petrol strips the lubrication your diesel’s fuel pump depends on, and running the engine spreads it through the system. Leave the key out, move clear of the bowser if safe, and call Wrong Fuel Help on 0432 553 905. We drain it on the spot, anywhere in Newcastle.

Service overview

Our process

step 1
Rapid Response

The moment you realise petrol has gone into your diesel engine, stop and do not start the engine, then call us on 0432 553 905. Our team will dispatch a fuel drain technician directly to your location across Newcastle, Maitland, Central Coast, Lake Macquarie and surrounding NSW regions, 24 hours a day, 7 days a week.

step 2
Petrol Extraction and System Flush

On arrival, our technician first confirms how far the petrol has travelled, including whether the engine was started or the ignition switched on. We then safely extract the entire petrol and diesel mix from the tank using specialist equipment, and flush the fuel lines, fuel filter and injection system until only clean diesel remains.

step 3
System Check and Refuel

Once the fuel system is fully clear of petrol, we refill your tank with fresh diesel, which we carry on board. We then carry out an engine start and running check to confirm everything is functioning correctly before we leave. Most petrol in diesel drains are completed on the spot in under an hour.

step 4
Preventive Measures

Before we leave, our technician confirms the engine is idling and running cleanly, checks for any fault codes if the vehicle was driven on the wrong fuel, and shares simple habits that prevent a repeat, like nozzle checks at unfamiliar servos and taking care when switching between petrol and diesel vehicles.

FAQs

FAQs About Petrol in a Diesel Car

Petrol in a diesel fuel system acts as a solvent instead of a lubricant. It strips the protective coating inside the high-pressure fuel pump and injectors, causing metal-on-metal friction. If the engine is started, this damage accelerates rapidly. If caught before starting, a professional fuel drain and flush is usually sufficient to prevent any lasting damage.

No. Do not drive or attempt to start the vehicle. Every metre driven on a petrol-diesel mixture increases the risk of damage to the fuel pump and injectors. Pull over safely, turn off the engine and call Wrong Fuel Help on 0432 553 905. Our mobile team comes to you – no tow truck required.

The cost depends on the vehicle type, tank size, how much petrol was added, and whether the engine was started or driven. Acting before starting the engine is almost always the most cost-effective option. Call Wrong Fuel Help on 0432 553 905 for an immediate, no-obligation quote.

Most petrol-in-diesel recovery jobs are completed in under 60 minutes. Our mobile technician drains the fuel tank, flushes the fuel lines and injection system, and refuels the vehicle with clean diesel – all at your location. No garage visit or tow truck is needed in the vast majority of cases.

Do not start the engine – this is the single most important action. If the nozzle is still in the tank, remove it. Put the car in neutral and push it away from the bowser if necessary. Then call Wrong Fuel Help immediately on 0432 553 905. We are available 24/7 across Newcastle and NSW.
