What Happens When You Put the Wrong Fuel in Your Car
Using the wrong fuel type can cause immediate and long-term damage to your vehicle’s engine and fuel system. Here’s what happens in the most common cases:
Petrol in a diesel tank: Diesel engines rely on the lubricating properties of diesel fuel. Petrol lacks this lubrication and can cause damage to the fuel pump and injectors. The engine may run roughly or fail to start.
Diesel in a petrol engine: Petrol engines ignite fuel with spark plugs, and diesel’s heavier composition can clog the system. The car may stall, smoke excessively, or not start at all.
AdBlue in a diesel tank: AdBlue is a urea solution used in selective catalytic reduction systems to reduce emissions. Adding it to the fuel tank can cause severe contamination and damage to the fuel system.
Each of these mistakes requires different responses, but the key is to act quickly to prevent further harm.
Immediate Steps to Take After Misfueling
If you realize you’ve put the wrong fuel in your car, follow these steps immediately:
Do not start the engine. Starting the car circulates the wrong fuel through the system, increasing damage.
Turn off the ignition and remove the key. This prevents accidental starting.
Call a professional service. In Dudley, Misfuelled Car Fix at 0800 999 1182 offers expert assistance to drain and clean your fuel system safely.
Avoid driving the vehicle. Even short distances can worsen the damage.
Quick action reduces repair costs and downtime.
How Professionals Fix Misfuelled Cars
Professional technicians use specialized equipment and techniques to fix misfueling problems safely:
Fuel system drainage: The contaminated fuel is completely drained from the tank and fuel lines.
Cleaning and flushing: Fuel filters, injectors, and pumps are cleaned or replaced if necessary.
System checks: The engine and fuel system are inspected for damage.
Refilling with correct fuel: After cleaning, the tank is refilled with the right fuel type.
Test drive: The vehicle is tested to ensure it runs smoothly.
Attempting to fix the problem yourself can cause more harm, so calling experts like Misfuelled Car Fix is the safest choice.
Preventing Wrong Fuel Mistakes in Dudley
Avoiding misfueling is better than fixing it. Here are practical tips to prevent putting the wrong fuel in your car:
Double-check the pump before filling: Look at the fuel type label on your car and the pump.
Use fuel caps with clear labels: Some aftermarket caps have “Diesel” or “Petrol” markings.
Stay focused at the pump: Avoid distractions like phones or conversations.
Ask for help if unsure: Petrol station attendants can assist if you’re uncertain.
Keep your vehicle’s fuel type in mind: If you drive multiple vehicles, be extra careful.
These habits reduce the risk of costly mistakes.
What to Do if You Suspect AdBlue Was Added to Your Diesel Tank
AdBlue is not a fuel but an additive for emissions control. If you accidentally add AdBlue to your diesel tank:
Do not start the engine. AdBlue can cause corrosion and damage.
Call a specialist immediately. The fuel system needs to be drained and flushed thoroughly.
Avoid trying to dilute the tank yourself. Adding water or other liquids can worsen the problem.
Professional help is essential to prevent expensive repairs.
