Petrol in a diesel car in Dartford: a local drainer comes to you
Put the keys in your pocket and ring 01295 380724. Petrol in a diesel car in Dartford 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.
Diesel lubricates the high-pressure pump as it passes through; petrol does the opposite and washes that film away, so the pump starts wearing within minutes of running. Left sitting in the tank, it is a small job.

When a drainer arrives in Dartford
Most of the time is spent draining. A full tank of the wrong fuel takes longer to pump than a few litres, so the drainer will tell you roughly how long it will be once they see the gauge. After that it is a flush, a refuel and a test run before they leave.
What to ask on the phone before a drainer travels to Dartford
You are going to pay for the job, so it is worth two minutes on the phone first. These are the questions that separate a straight quote from a surprise at the roadside.
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Do you take card payment at the roadside?
- How much more if the engine has already been started?
- What is the total, not just the call-out, if it is a straight drain?
- 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 Dartford.
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
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
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.
Do you work at night in Dartford?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
What does it cost in Dartford?
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.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
