Wrong fuel engine damage in London: a local drainer comes to you
If the engine has not run, wrong fuel engine damage in London is usually a clean drain with no lasting harm. Keep it that way — don't start it — and ring 01295 380724. The call-out is £89, the drainer brings everything, and most jobs are done in 1 to 3 hours.
In the tank it harms nothing. It is the pump and injectors that suffer once it circulates, which is where the cost comes from.

What the drainer does when they reach you in London
The drainer parks up, checks the vehicle has not been started and makes the area safe with cones and a drip tray. The fuel is pumped out through the filler or the fuel line into a sealed tank on the van, the lines are flushed, a few litres of the right fuel go in, and the engine is started and run until it idles cleanly. The contaminated fuel leaves with them.
Before you agree a price: what to ask
You are going to pay for the job, so it is worth two minutes on the phone first. These are the questions that separate a straight quote from a surprise at the roadside.
- How much more if the engine has already been started?
- Can you work on the forecourt, or does the car need to be moved?
- Do you take card payment at the roadside?
- What is the total, not just the call-out, if it is a straight drain?
- Is there an extra charge at night or at the weekend?
What to do right now
- Keep the engine off and put the keys somewhere you will not absent-mindedly use them.
- Move the car only by pushing, with help, and only if it is blocking a pump.
- Phone 01295 380724 and describe what happened.
- Confirm the quote — call-out from £89 — and the arrival window.
- The drainer empties the tank into a sealed container and flushes through.
- After a refuel and a test run, the waste fuel leaves with the drainer for licensed disposal.

Answers
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 in London.
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
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
Do you work at night in London?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
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.
Do I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
How long does a drain take in London?
Usually 1 to 3 hours on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
Can I drive to a garage with wrong fuel engine damage?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
