Misfuel in Windsor: a local drainer comes to you
Stop, switch nothing on, and call 01295 380724. Local drainers across Windsor handle misfuel every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 45 to 90 minutes on site and a call-out from £89, with the full price given before they leave for you.
What matters most is whether the fuel has moved beyond the tank. Misfuelling is the trade's word for filling up with the wrong fuel. It is fixed on site with a drain and a flush.

What the drainer does when they reach you in Windsor
On a forecourt the drainer will usually move the vehicle off the pump lane first, by hand, with the engine off. Then it is drain, flush, refuel and start. At home or at work they can do the whole thing on the drive or in the car park without moving it at all.
Five things to ask a drainer before they set off
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Is there an extra charge at night or at the weekend?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Will you check the filter and pump if the engine ran?
- Do you take card payment at the roadside?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

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 in Windsor.
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
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.
Do you cover all of Windsor?
Yes — forecourts, roadsides, homes and workplaces across Windsor and the surrounding area.
Do you work at night in Windsor?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
