Red diesel in the tank in Slough, drained on the spot
Do not turn the ignition, not even to check the dashboard. For red diesel in the tank anywhere in Slough, a drainer attends with a pump and a sealed tank, empties the fuel system and refills it. From £89 call-out, usually 1 to 2 hours on site; ring 01295 380724 for the price before you commit.
Here is why it matters. Mechanically red diesel runs, but in a road vehicle it is a duty offence; the tank is drained, flushed and the fuel disposed of under licence.

The drain itself, step by step in Slough
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.
Questions worth asking before you book a drain in Slough
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.
- Will you dispose of the contaminated fuel, and can I have a note of it?
- 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?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- How long until you reach me in Slough?
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 Slough.
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
Do you work at night in Slough?
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.
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.
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.
How quickly can a drainer reach me in Slough?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
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.
