PETROL IN DIESEL ENGINE
Petrol in Diesel Car is one of the most common misfuelling mistakes and can cause serious damage if not handled quickly. When petrol enters a diesel engine, it reduces the lubrication that diesel components rely on, leading to friction, wear, and potential failure of injectors, pumps, and fuel lines. Starting the engine makes the situation worse, as the wrong fuel circulates throughout the system and creates a harmful mixed fuel that can cause long-term engine problems. Stopping the vehicle immediately and getting a professional mobile fuel drain is the safest way to protect your engine and minimise repair costs.
Comprehensive Fuel System Cleansing Treatment
One of the most crucial steps in recovering a vehicle from misfuelling is thoroughly purging the fuel system to eliminate any cross-contamination.
We begin by completely draining the fuel tank, ensuring every drop of contaminated fuel is removed—including any that has already reached the fuel filter through the fuel pump. Next, we flush the fuel pump with fresh fuel, combined with a small amount of injector cleaning solution, to cleanse the fuel injectors. This fuel is then drained as well to ensure no traces of the wrong fuel remain.
Once the system is clear, we refill your vehicle with the correct fuel—ideally, a full tank—to help dilute and neutralize any residual contamination. In some cases, depending on the engine type, we may need to initiate ignition directly through the air filter to get the engine running smoothly. After a short drive, typically about a mile, your vehicle will be fully restored to its optimal condition.

How Wrong Fuel Affects Your Engine
Using the wrong fuel can cause immediate and long-term damage to your vehicle’s engine and fuel system. When petrol enters a diesel engine, it removes the lubrication that diesel components rely on, leading to rapid wear of injectors, pumps, and seals. In the case of diesel entering a petrol engine, the thicker fuel prevents proper combustion and can clog spark plugs, filters, and fuel lines. If the engine is started, the wrong fuel is pushed throughout the entire system, increasing repair costs and potentially causing irreversible internal damage. That’s why stopping the vehicle and avoiding ignition is the most crucial first step.
Why Immediate Fuel Drain Matters
Immediate fuel drainage is essential because it prevents the contaminated mixture from circulating into critical components, reducing the risk of costly repairs. A fast response ensures the wrong fuel is removed before it reaches injectors, fuel pumps, and combustion chambers, all of which are sensitive to contamination. Delaying fuel drain allows the mixture to settle and spread, making the cleanup process more complex and increasing the likelihood of long-term engine problems. Calling a professional mobile fuel drain service right away ensures your system is flushed correctly, your tank is cleaned safely, and your vehicle is protected from further damage.
