Diesel in petrol in Thornbury? Drained where it stands
Leave the engine off. With diesel in a petrol car in Thornbury, the fix is a local drainer who comes to the vehicle, pumps the tank out, flushes the lines and puts clean fuel in. Call 01295 380724: the call-out starts at £89, the job usually takes 45 to 90 minutes, and you hear the full price before anyone sets off.
The mechanism is simple. A petrol engine lights its fuel with a spark, and diesel barely lights that way, so you get misfiring, smoke and eventually a car that will not start.

On arrival in Thornbury: what happens next
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.
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.
- Do you bring clean fuel, and is it included?
- Is there an extra charge at night or at the weekend?
- How much more if the engine has already been started?
- Will you check the filter and pump if the engine ran?
- Can you work on the forecourt, or does the car need to be moved?
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.

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
Do you work at night in Thornbury?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
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.
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.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
Can I drive to a garage with diesel in a petrol car?
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.
Do you cover all of Thornbury?
Yes — forecourts, roadsides, homes and workplaces across Thornbury and the surrounding area.
