Diesel in a petrol car in Dorking, drained on the spot
Put the keys in your pocket and ring 01295 380724. Diesel in a petrol car in Dorking is a drain-and-flush job done at the roadside, on the forecourt or on your drive — no tow, no garage. Call-out from £89, roughly 45 to 90 minutes on site, price agreed first.
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.

What the drainer does when they reach you in Dorking
They bring the fuel. Once the tank is empty and the lines are flushed, the drainer adds enough of the correct fuel to get the engine running and to reach a filling station, then checks for warning lights before handing the keys back.
What to ask on the phone before a drainer travels to Dorking
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Do you bring clean fuel, and is it included?
- How long until you reach me in Dorking?
- Is there an extra charge at night or at the weekend?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Will you check the filter and pump if the engine ran?
What to do right now
- Keep the engine off and put the keys somewhere you will not absent-mindedly use them.
- Move the car only by pushing, with help, and only if it is blocking a pump.
- Phone 01295 380724 and describe what happened.
- Confirm the quote — call-out from £89 — and the arrival window.
- The drainer empties the tank into a sealed container and flushes through.
- After a refuel and a test run, the waste fuel leaves with the drainer for licensed disposal.

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 Dorking.
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
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.
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.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
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.
