Petrol in AdBlue tank in Slough? Drained where it stands
Keys out, bonnet shut, hazards on if you are at the roadside. Petrol in the AdBlue tank in Slough is drained on site by a local drainer: pumped out, flushed and refilled in about 1 to 3 hours. Call-out from £89 — call 01295 380724 and you get the figure before anyone drives to you.
Here is why it matters. Petrol in the AdBlue tank damages the SCR components that meter the urea into the exhaust. Drain it before the engine runs.

When a drainer arrives in Slough
First they confirm what went in and how much, and whether the engine ran — that decides how far they need to go. Then the tank is emptied into a sealed container, the fuel lines and filter are flushed where needed, clean fuel is added and the vehicle is started and checked before they sign it off.
Questions worth asking before you book a drain in Slough
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?
- Can you work on the forecourt, or does the car need to be moved?
- 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?
- Will you check the filter and pump if the engine ran?
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 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 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.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
Does insurance cover petrol in the adblue tank?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
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.
