Petrol in the AdBlue tank in Windsor: a local drainer comes to you
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Windsor drains petrol in the adblue tank on the spot, flushes through and refuels, typically in 1 to 3 hours, with a call-out from £89 confirmed up front.
Petrol in the AdBlue tank damages the SCR components that meter the urea into the exhaust. Drain it before the engine runs. Left sitting in the tank, it is a small job.

What the drainer does when they reach you in Windsor
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.
Five things to ask a drainer before they set off
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Do you bring clean fuel, and is it included?
- How much more if the engine has already been started?
- What is the total, not just the call-out, if it is a straight drain?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Can you work on the forecourt, or does the car need to be moved?
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 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
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.
Can I drive to a garage with petrol in the adblue tank?
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.
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
What does it cost in Windsor?
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.
