Gasoline in diesel in Dartford, drained on the spot
Before anything else, keep the key out of the ignition. A drainer covering Dartford can be with you the same day for gasoline in diesel, drain it where the car stands and have you moving in about 45 to 90 minutes. The misfuel call-out is £89 and the total is quoted on 01295 380724 before they travel.
Gasoline is petrol. In a diesel engine it thins the fuel and takes away the lubrication the pump and injectors need. Left sitting in the tank, it is a small job.

What the drainer does when they reach you in Dartford
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
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.
- What is the total, not just the call-out, if it is a straight drain?
- How long until you reach me in Dartford?
- Can you work on the forecourt, or does the car need to be moved?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Will you check the filter and pump if the engine ran?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

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 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
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
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 you work at night in Dartford?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
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 I pay by card?
Yes. Card payment is taken on site once the job is done.
Do you cover all of Dartford?
Yes — forecourts, roadsides, homes and workplaces across Dartford and the surrounding area.
