How Wrong Fuel Affects Your Vehicle
Putting the wrong fuel in your vehicle disrupts the engine’s operation and can cause damage to critical components. Here’s what happens with the most common mistakes:
Petrol in a diesel engine: Diesel engines rely on the lubricating properties of diesel fuel. Petrol acts as a solvent and reduces lubrication, which can cause damage to the fuel pump and injectors. The engine may misfire, stall, or fail to start.
Diesel in a petrol engine: Petrol engines ignite fuel with a spark, but diesel is heavier and ignites differently. Diesel in a petrol engine can cause rough running, smoke, and damage to spark plugs and catalytic converters.
AdBlue in the diesel tank: AdBlue is a urea solution used in selective catalytic reduction systems to reduce emissions. If AdBlue is accidentally poured into the diesel tank, it can cause severe corrosion and damage to the fuel system.
Understanding these effects highlights why immediate action is crucial.
What to Do Immediately After Realizing the Mistake
If you notice you’ve put the wrong fuel in your vehicle, follow these steps without delay:
Do not start the engine
Starting the engine circulates the wrong fuel through the system, increasing the risk of damage.
Turn off the ignition
If the engine is running, switch it off immediately to prevent further damage.

Check the fuel type before filling
Always double-check the pump label and your vehicle’s fuel cap.
Use clear labels on your vehicle
Some drivers place stickers near the fuel cap indicating the correct fuel type.
Stay focused at the pump
Avoid distractions like phones or conversations while refueling.
Educate other drivers
If multiple people use your vehicle, ensure they know the correct fuel type.
Be cautious with AdBlue
Only add AdBlue to the designated tank, usually clearly marked and separate from the fuel filler.
What Happens If You Start the Engine with the Wrong Fuel?
Starting the engine after adding the wrong fuel can cause:
Fuel pump damage
Petrol in diesel engines reduces lubrication, causing pumps to wear out quickly.
Clogged fuel filters
Diesel in petrol engines can clog filters and injectors.
Engine misfire and stalling
The wrong fuel disrupts combustion, leading to poor performance or engine failure.
Costly repairs
Repairing or replacing fuel pumps, injectors, and filters can be expensive.
If you have already started the engine, stop driving immediately and call a wrong fuel emergency service.
