Filling your tank with the wrong fuel is a mistake that can happen in seconds—but the consequences can be serious and expensive. Whether it’s a moment of distraction or confusion at the pump, misfuelling can damage your engine and leave you stranded. That’s where Fuel Doctor, the UK’s trusted wrong fuel removal service, comes in.
Available around the clock, Fuel Doctor specializes in fast, mobile fuel drain services to rescue motorists from one of the most stressful roadside errors. This article explains everything you need to know about misfuelling, the risks involved, and why Fuel Doctor should be your first call.
How Does Misfuelling Happen?
Misfuelling typically occurs when:
-
You’re rushing or distracted while filling up.
-
You drive multiple vehicles with different fuel types.
-
You’re using a rental, company, or new car with unfamiliar fuel requirements.
-
Fuel pump handles are colour-coded but often confusing, especially in poor lighting or bad weather.
In the UK, petrol nozzles easily fit into diesel tanks, making petrol-in-diesel the most frequent issue. Diesel in a petrol car is less common, but it does happen.
What Can Go Wrong?
Putting the wrong fuel in your car isn’t just a minor inconvenience—it can cause mechanical damage if not handled immediately:
-
Petrol in a diesel engine: Strips lubrication from fuel components, potentially damaging the fuel pump and injectors.
-
Diesel in a petrol engine: Causes poor combustion, clogs spark plugs, and can lead to engine misfire or stalling.
Even if you drive just a short distance after misfuelling, the wrong fuel can circulate and contaminate the entire system.
What to Do Right Away
If you suspect or know you’ve misfuelled, act quickly:
-
Do not start your engine.
-
If you’ve already started it, switch it off immediately.
-
Push the vehicle to a safe spot.
-
Call Fuel Doctor.
Attempting to drive, siphon the fuel yourself, or wait too long can escalate the damage. A quick response is crucial.
