- Drain petrol from a diesel car or van
- Drain diesel from a petrol car
- Remove AdBlue from a fuel tank
- Drain contaminated or stale fuel from any tank
- Flush fuel lines, filter and injectors

Misfuel Emergency FAQs
Quick answers for when you're stuck at the pump.
Are you fully insured for mobile fuel drains?
Yes. We carry comprehensive insurance specifically for mobile fuel drain work, and our technicians are fully qualified SPA/PIA safety passport holders who follow strict safety procedures.
How long does the fuel drain process take?
Once we arrive, draining and flushing usually takes 20-40 minutes depending on the vehicle type and how much fuel is in the tank.
Will a roadside fuel drain void my car warranty?
No. We carry out a professional fuel drain and flush that is compliant with manufacturer requirements. Dealerships often suggest expensive full-system replacements, but a correctly performed roadside flush is safe and recognised by many insurers.
Can you help me if I am on a busy motorway?
Yes, safety permitting. We recommend moving to a safe location if you can, and we coordinate with National Highways where necessary to make sure the recovery is carried out safely.
Can I drain the fuel tank myself?
We strongly advise against it. Most modern tanks have no drain plug and an anti-siphon valve in the filler neck, the fuel is a fire hazard, and the contaminated fuel has to be disposed of as hazardous waste. A mobile fuel drain removes it safely with a pump, flushes the lines and filter, and is usually done within 30-45 minutes.
Is this the same as a 'fuel doctor' or 'fuel fixer' service?
Yes. 'Fuel doctor', 'diesel doctor' and 'fuel fixer' are all names people use for a mobile wrong fuel technician. Wrong Fuel Rescue is an independent London-based service that drains and flushes the wrong fuel at the roadside, 24 hours a day, with a fixed price agreed before we set off.
