Wrong fuel: what a drainer does about it
Leave the engine off. With wrong fuel in the UK, the fix is a local drainer who comes to the vehicle, pumps the tank out, flushes the lines and puts clean fuel in. Call 01295 380724: the call-out starts at £89, the job usually takes 45 to 90 minutes, and you hear the full price before anyone sets off.
What matters most is whether the fuel has moved beyond the tank. Whatever went in, the order is the same: engine off, drain, flush, refuel. The earlier it is caught, the smaller the job.

How worried should you be about wrong fuel?
Whatever went in, the order is the same: engine off, drain, flush, refuel. The earlier it is caught, the smaller the job. The drainer asks three things before anything else: what went in, how much, and whether the engine ran. Those answers decide the whole job.
Where it goes wrong
The mistake is usually spotted within seconds — the price looks wrong, or the nozzle colour registers late. That is the best time to catch it, because the engine has not run.
The drain itself, step by step in the UK
They bring the fuel. Once the tank is empty and the lines are flushed, the drainer adds enough of the correct fuel to get the engine running and to reach a filling station, then checks for warning lights before handing the keys back.
Five things to ask a drainer before they set off
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- How much more if the engine has already been started?
- Do you take card payment at the roadside?
- Can you work on the forecourt, or does the car need to be moved?
- Will you check the filter and pump if the engine ran?
- Do you bring clean fuel, and is it included?
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
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
What if I have already driven home?
Leave it on the drive with the engine off and call 01295 380724. The drainer can do the whole job at your house.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
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.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
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.
