What Happens When You Put the Wrong Fuel in Cambourne?

Using the wrong fuel affects your engine and fuel system differently depending on the type of misfueling:

• Petrol in a diesel car: Petrol acts as a solvent and can damage the diesel fuel pump and injectors. Diesel engines rely on the lubricating properties of diesel, so petrol reduces lubrication, causing wear and potential failure.

• Diesel in a petrol car: Diesel is heavier and less volatile than petrol, so it won’t ignite properly in a petrol engine. This can cause the engine to misfire, stall, or fail to start.

• AdBlue in the diesel tank: AdBlue is a urea solution used in selective catalytic reduction systems to reduce emissions. Putting AdBlue in the diesel tank can cause severe damage to the fuel system and engine.

  
  

The severity of the damage depends on how much wrong fuel was added and whether the engine was started after misfueling.

Immediate Steps to Take If You Realize You’ve Misfuelled

1. Do Not Start the Engine

If you notice the mistake before starting the car, do not turn on the ignition. Starting the engine circulates the wrong fuel through the system, increasing the risk of damage.

2. Turn Off the Engine Immediately

If you have already started the engine and realize the error, switch it off as soon as possible. Continuing to run the engine can cause more damage.

3. Call a Professional Misfuelled Car Fixer

Contact a specialist like Misfuelled Car Fixer in Cambourne at 0330 122 6640. They have the right tools and expertise to drain and clean your fuel system safely.

4. Avoid Driving the Vehicle

Even if the car seems to run fine, driving it can spread the wrong fuel through the system. This can lead to costly repairs.
