When a drainer arrives in Thornbury
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.
Before you agree a price: what to ask
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- What is the total, not just the call-out, if it is a straight drain?
- Will you check the filter and pump if the engine ran?
- Do you take card payment at the roadside?
- Do you bring clean fuel, and is it included?
- Will you dispose of the contaminated fuel, and can I have a note of it?
What to do right now
- Don't turn the key.
- Check what went in: the receipt and the pump number tell you the fuel and the litres.
- Call 01295 380724 with those details and your location.
- Get a price that covers the whole job, then book.
- The drainer arrives, drains the tank, flushes the lines and filter if needed.
- You get clean fuel, a running engine and a note of what was removed.

Where you can be drained in Thornbury
Most drains in Thornbury happen on the forecourt where the mistake was made. The rest are at the roadside after the car cut out, or on a drive the next morning. All three work; the vehicle does not need to be towed anywhere.
If you are just outside Thornbury, you are probably still in range: Rudgeway, Almondsbury, Barkerend and Bradford Moor are all covered by the same drainers.

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 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
Does insurance cover wrong fuel?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Can I drive to a garage with wrong fuel?
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.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
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.
