What to expect from the drainer in Thornbury
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.
Before you agree a price: what to ask
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- What is the total, not just the call-out, if it is a straight drain?
- How long until you reach me in Thornbury?
- Is there an extra charge at night or at the weekend?
- Do you take card payment at the roadside?
- How much more if the engine has already been started?
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.

Answers
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 Thornbury.
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
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
How quickly can a drainer reach me in Thornbury?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
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.
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 drive to a garage with mobile fuel drain?
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.
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.
