Putting the wrong fuel in your vehicle can cause serious damage and disrupt your day. Whether it’s petrol in a diesel car, diesel in a petrol engine, or even AdBlue mistakenly added to the diesel tank, the consequences can be costly and stressful. If you find yourself in this situation in Harwich or Essex, knowing the right steps to take can save you time, money, and frustration.
This guide explains how to handle wrong fuel problems effectively, what to avoid, and how professional help like Misfuelled Car Fixer Essex can assist you.

Common Types of Wrong Fuel Mistakes
Wrong fuel issues usually fall into one of these categories:
Petrol in a diesel vehicle: Petrol can damage diesel engines because it reduces lubrication, causing wear and potential engine failure.
Diesel in a petrol vehicle: Diesel can clog spark plugs and fuel injectors, leading to poor engine performance or stalling.
AdBlue in the diesel tank: AdBlue is a urea solution used in selective catalytic reduction systems. Adding it to the diesel tank can cause severe engine damage and expensive repairs.
Each mistake requires a different approach to fix, so identifying the exact problem is the first step.
Immediate Actions to Take After Misfuelling
If you realize you have put the wrong fuel in your car, act quickly to reduce damage:
Do not start the engine. Starting the car circulates the wrong fuel through the system, increasing the risk of damage.
Turn off the ignition immediately. If the engine is running, switch it off as soon as possible.
