Misfueling a vehicle is a common mistake that can lead to costly repairs and significant inconvenience. In Ely, Cambridgeshire, drivers sometimes accidentally put unleaded petrol in diesel cars, diesel in unleaded vehicles, or even AdBlue into the diesel tank. These errors can cause engine damage if not addressed quickly and correctly. This guide explains how to identify misfueling, what steps to take immediately, and how to prevent these mistakes in the future.

Recognizing Wrong Fuel in Ely, Cambridgeshire
The first step in resolving a misfueling issue is to recognize it as soon as possible. Signs that you may have put the wrong fuel in your vehicle include:
Engine warning lights turning on shortly after refueling.
Difficulty starting the engine or the engine stalling.
Unusual noises from the engine or rough idling.
Loss of power or poor acceleration.
Strong fuel smell inside or outside the vehicle.
If you notice any of these symptoms after filling up, it’s crucial to act quickly to avoid further damage.
What to Do If You Put Unleaded Petrol in a Diesel Car
Putting unleaded petrol in a diesel car is one of the most common misfueling mistakes. Petrol can damage the diesel fuel system and engine components because it lacks the lubricating properties diesel fuel provides.
Immediate Steps
Do not start the engine. Starting the engine circulates the petrol through the diesel system, increasing the risk of damage.
Call a professional service like Misfuelled Car Fixer at 0330 122 6640. They can arrange to drain the incorrect fuel safely.
If you have already started the engine, turn it off immediately and seek professional help.
Repair Process
A specialist will drain the fuel tank and flush the fuel lines and filters. In some cases, parts like fuel pumps or injectors may need replacement if damaged. Early intervention reduces repair costs and downtime.
What to Do If You Put Diesel in an Unleaded Petrol Car
Diesel fuel in a petrol engine causes different problems. Diesel is heavier and does not evaporate like petrol, leading to clogging and poor combustion.
Immediate Steps
Avoid starting the engine. Diesel in a petrol engine can cause misfires and damage.
Contact Misfuelled Car Fixer on 0330 122 6640 for assistance.
If the engine has started, turn it off as soon as possible.
Repair Process
The vehicle will require draining of the fuel tank and cleaning of the fuel system. Diesel residues can clog spark plugs and fuel injectors, so these components may need inspection or replacement.
What Happens If AdBlue Is Put in a Diesel Tank
AdBlue is a urea-based fluid used in selective catalytic reduction systems to reduce emissions. Accidentally filling the diesel tank with AdBlue can cause severe engine damage.
Immediate Steps
Do not start the engine. AdBlue in the diesel tank can corrode fuel system components.
Call Misfuelled Car Fixer at 0330 122 6640 immediately.
The vehicle must be towed to a specialist workshop for cleaning.
Repair Process
The fuel tank and lines must be thoroughly cleaned and flushed. AdBlue contamination can lead to corrosion of metal parts, so early professional intervention is critical.
Preventing Misfueling Mistakes
Avoiding misfueling saves time, money, and stress. Here are practical tips for drivers if wrong fuel in Ely, Cambridgeshire:
Double-check the fuel type before filling. Look at the fuel cap and pump labels carefully.
Use reminders. Place a sticker inside the fuel door or near the driver’s seat indicating the correct fuel type.
