Is wrong fuel drain cost serious?
It depends almost entirely on the ignition. The call-out is £89. What goes on top depends on how far the wrong fuel travelled, and you hear the full number before anyone sets off. If the engine has not run, the fuel is still in the tank and a drain takes it out cleanly. If it has, the pump, filter and injectors come into it, and the job gets longer.
Why this happens
It is almost always a moment of autopilot: a borrowed car, a new car with a different fuel type, or a pump layout that is not the one you are used to. Nobody is careless in the ordinary sense — the forecourt is set up to make this easy to do.
What the drainer does when they reach you in the UK
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
What to ask on the phone before a drainer travels to the UK
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Will you check the filter and pump if the engine ran?
- Is there an extra charge at night or at the weekend?
- What is the total, not just the call-out, if it is a straight drain?
- Can you work on the forecourt, or does the car need to be moved?
- How much more if the engine has already been started?
What to do right now
- Leave the ignition alone — on many cars even unlocking it powers the fuel pump.
- Push the car clear of the pump if needed, with someone steering and the engine off.
- Call 01295 380724 and give the fuel, the amount and your exact location.
- Ask for the whole price, not just the call-out, and agree it.
- The drainer drains the tank into a sealed container and flushes the lines.
- Fresh fuel goes in, the engine is started and the waste fuel leaves with the drainer.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Does insurance cover wrong fuel drain cost?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Will the car need a service afterwards?
Not after a straight drain. If the engine ran on the wrong fuel, the drainer will tell you whether the filter should be changed.
What does it cost in the UK?
The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels.
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
How long does a drain take in the UK?
Usually 45 to 90 minutes on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
