Putting the wrong fuel in your vehicle is a stressful experience. It can cause serious damage if not addressed quickly and correctly. I’ve been through this situation and learned the best steps to take to resolve it effectively. This guide will walk you through the process of correcting vehicle misfuels, helping you avoid costly repairs and get back on the road safely.
Understanding the Impact of Misfuelling and Correcting Vehicle Misfuels
Misfuelling happens when petrol is put into a diesel car or diesel into a petrol car. Sometimes, AdBlue is mistakenly added to the fuel tank. Each of these errors can cause different types of damage. Knowing what happens inside your engine when the wrong fuel is added is crucial.
When petrol enters a diesel engine, it acts like a solvent, reducing lubrication and causing wear on fuel pumps and injectors. Diesel in a petrol engine can clog spark plugs and cause misfires. AdBlue in the fuel tank can severely damage the fuel system and catalytic converter.
The first step in correcting vehicle misfuels is to stop driving immediately. Continuing to drive spreads the wrong fuel through the system, increasing damage and repair costs. Turn off the engine and do not attempt to start it again.

Immediate Actions to Take After Misfuelling
Once you realise the mistake, act fast. Here’s what you should do:
Do not start the engine - Starting the engine circulates the wrong fuel, making the problem worse.
Call a professional emergency service - Specialists can drain the incorrect fuel safely and prevent damage.
Inform your insurance company - Some policies cover misfuelling incidents.
Avoid trying to fix it yourself - Draining fuel requires special equipment and knowledge.
If you’re wondering how to fix wrong fuel in car, professional roadside services are your best option. They have the tools to drain and flush the fuel system quickly and safely.
How to fix a car with the wrong gas in it?
Fixing a car with the wrong gas involves several technical steps. Here’s a detailed breakdown:
Fuel system drainage: The incorrect fuel must be completely drained from the tank and fuel lines. This prevents further contamination.
Fuel filter replacement: The fuel filter often traps contaminants and must be replaced to avoid clogging.
Fuel system flushing: After draining, the system is flushed with the correct fuel to remove any residue.
Component inspection: Fuel pumps, injectors, and spark plugs should be checked for damage.
Engine oil check: Sometimes, the wrong fuel contaminates the engine oil, requiring an oil change.
Test drive: After repairs, a test drive ensures the vehicle runs smoothly.
Attempting these steps without professional help can lead to incomplete removal of the wrong fuel and costly repairs. Emergency fuel drainage services specialise in this process and can save you time and money.
