Poured petrol into a diesel engine or diesel into a petrol tank? Keep your engine turned off and do not turn key position II.
Misfuelled Car Fixer provides specialized mobile fuel evacuation and decontamination for drivers stranded at petrol station forecourts, private driveways, commercial yards, and off-highway parking bays across the UK. Our SPA-accredited mechanics utilize commercial suction rigs to purge contaminated fuel, flush system lines, and safely re-prime your motor.
⚠️ IMPORTANT SAFETY & HIGHWAY POLICY
We do not attend breakdowns directly on active motorway carriageways, hard shoulders, or live A-road traffic lanes. Working on live high-speed roads poses extreme safety risks to motorists and technicians. If your vehicle has cut out on a motorway or major trunk road, you must immediately move to a safe location behind the barrier and call a high-speed vehicle recovery service or highway authorities to tow your car to a safe off-road parking site or service area before we can assist.
On-Site Decontamination Solutions
When fuel types are mixed, operating the ignition circulates unrefined or unlubricated fluid through fragile mechanical components. We perform full-system flushes on-site to extract fluid mixtures before internal parts suffer premature wear.
Core Extraction Capabilities:
- Unleaded in Diesel Systems: Petrol degrades the protective oil barrier required by high-pressure diesel injection pumps. We evacuate the tank completely and purge supply pipes to protect your pump assembly.
- Diesel in Unleaded Systems: Heavier diesel fluid fouls spark plugs, restricts fuel injectors, and leads to severe engine misfiring. We clear out contaminated fuel and clean combustion pathways.
Specialist Chemical & AdBlue Purging:
- AdBlue Contamination in Fuel Tanks: Pouring urea-based AdBlue solution into fuel causes immediate chemical crystallization. We conduct complete reservoir extractions and Selective Catalytic Reduction (SCR) pipe flushing.
- Fuel in AdBlue Reservoirs: We siphon out diesel or petrol from dedicated AdBlue tanks to protect sensitive exhaust gas sensors.
- Motorcycle Misfuel Recovery: Safe, manual fuel siphoning for bikes, scooters, and quads without scratching tank paintwork.
- Screenwash in AdBlue Systems: Specialized reservoir drains to preserve your exhaust treatment network.
Standard petrol or diesel fuel extractions start FROM £150.00, while complex AdBlue decontamination starts FROM £349.00.

If you are currently parked safely off the main carriageway, dial 0330 122 6640 for immediate technical assistance.
Step-by-Step Response Protocol
Keep the Ignition Off: Do not put the key in the ignition or press the start button.
Ensure Safe Placement: If you are at a petrol station, ask staff or bystanders to help push your vehicle to an off-court parking bay if safe. If on a main road, move to a safe area off the highway.
Contact Dispatch: Call 0330 122 6640 with your vehicle registration, current off-road address, and an estimate of how much incorrect fuel was added.
On-Site Resolution: Our technician extracts the bad fuel, flushes the lines, supplies fresh fuel, and performs a controlled test start.
Common Misfuelling Inquiries
What if I am currently broken down on a motorway or major A-road?
For safety reasons, our technicians cannot attend live motorway lanes or hard shoulders. You must contact a regional breakdown towing operator to transport your vehicle off the motorway to a safe local location, service station, or car park first. Once your vehicle is off the high-speed road, call us to perform the fuel drain.
Can you perform fuel drains on petrol station forecourts?
Yes. Our engineers carry Safety Pass Alliance (SPA) forecourt safety passes and use spark-proof ATEX-certified extraction rigs, allowing us to legally and safely clear tanks directly at fuel stations.
What happens if I started the car and drove a short distance before stopping?
Turn the engine off immediately. While driving circulates bad fuel through the system, a high-pressure line purge and filter replacement during the drain process usually restores proper operation without requiring garage teardowns.
