AdBlue in the petrol tank in Caterham: a local drainer comes to you
Keys out, bonnet shut, hazards on if you are at the roadside. AdBlue in the petrol tank in Caterham 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.
The mechanism is simple. AdBlue is mostly water with urea in it; in a petrol tank it corrodes the fuel system and needs a full drain and flush.

What to expect from the drainer in Caterham
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
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.
- What is the total, not just the call-out, if it is a straight drain?
- Do you bring clean fuel, and is it included?
- How much more if the engine has already been started?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Do you take card payment at the roadside?
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 Caterham.
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.
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.
Does insurance cover adblue in the petrol tank?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
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 does it cost in Caterham?
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.
