It’s an incredibly easy mistake to make. You’re rushing down the A1012, thinking about your to-do list, and you pull into the nearest petrol station forecourt. Before you know it, you’ve grabbed the wrong nozzle and put petrol in a diesel car—or vice versa.
If you are currently sitting in your car in Grays panicking, take a deep breath. Misfuelling happens to a UK motorist every three minutes.
The most important thing you can do right now is read this guide and follow these exact steps to protect your engine and get back on the road safely.
If you didn’t catch the mistake at the pump but your vehicle has started acting strangely as you drive along the A49 or through the town centre, look out for these classic symptoms of misfuelling:
Petrol in a Diesel Vehicle: A loud knocking noise when accelerating, rough or uneven idling, a heavy cloud of smoke from the exhaust, or an engine that suddenly loses all power and cuts out.
Diesel in a Petrol Vehicle: The engine heavily misfiring, a severe lack of acceleration power, excessive smoking, and a car that repeatedly stalls and refuses to restart.
Diesel in a Motorbike Tank: Because motorcycle engines run on petrol, putting diesel in them will rapidly foul the spark plugs. Your bike will start blowing thick white or blue smoke, lose all throttle response, misfire heavily, and ultimately cut out and refuse to restart.
AdBlue in a Diesel Tank: Because AdBlue is mostly water and urea, it doesn't burn. Symptoms include an immediate loss of engine power, severe sputtering, a rapid engine stall, and the dashboard lighting up with multiple engine management errors. Note: AdBlue is highly corrosive to diesel fuel systems, so do not crank the engine!
Screenwash in an AdBlue Tank: This will quickly contaminate the selective catalytic reduction (SCR) system. You will usually see an AdBlue system fault light on your dashboard, a countdown warning preventing the engine from restarting, or the vehicle entering a restricted "limp mode" as the sensors detect the chemical imbalance.
Step 1: The Golden Rule – DO NOT Turn the Key
Whether you are still parked at the Sainsbury's fuel pumps in Chafford Hundred, at a forecourt off the A13, or sitting on your driveway in Grays, do not turn on the ignition.
Why? Simply turning the key to power up the dashboard can engage the fuel pump. This immediately draws the contaminated fuel out of the tank and into your engine's delicate fuel lines.
If you haven't started the engine: The wrong fuel is safely contained in the tank, making it a quick and easy fix.
If you've already started driving: Pull over safely as soon as possible and cut the engine immediately.
