What to do if you put petrol in a diesel car
Four quick steps before we start petrol draining. Get the car safe, then get us on the phone.
01 Leave the ignition off
Do not turn the key after putting petrol in a diesel car. Contaminated fuel stays in the tank until petrol draining begins.
02 Tell forecourt staff
Ask for help to push the car clear of the pumps if you are still on the forecourt.
03 Move somewhere safe
Get the vehicle out of traffic. Share a road name, postcode, or shop name when you call for a petrol drain.
04 Call Fuel Flush
Call 07933 620 900. We confirm your location and dispatch a mobile petrol draining van.
Petrol in your diesel tank? Do not start the engine
Turning the key after putting petrol in a diesel car circulates contaminated fuel into the high-pressure pump and injectors. Keep ignition OFF and call Fuel Flush for immediate petrol draining.
Call 24/7: 07933 620 900What happens when petrol goes in a diesel tank
Putting petrol in a diesel car is the most common misfuel in the UK. Unleaded petrol strips the lubrication diesel pumps and injectors need. If you turn the key or drive, damage risk rises fast. Fuel Flush provides roadside petrol draining, flushes the fuel system, and tops up with clean diesel so you can drive away.
- Mobile petrol drain for cars, vans, and light commercials
- Forecourt-safe ATEX petrol draining equipment
- Most petrol in diesel drains take 20 to 35 minutes on scene
Petrol strips lubrication
Diesel pumps rely on diesel for lubrication. Unleaded petrol acts like a solvent and wears parts fast.
Metal particles can spread
If driven after petrol in diesel, pump wear can send fine metal through injectors and lines.
Fast petrol draining limits damage
A prompt petrol drain and diesel flush usually gets most cars back on the road the same visit.
