Petrol in a diesel car in Southampton: a local drainer comes to you
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Southampton drains petrol in a diesel car on the spot, flushes through and refuels, typically in 45 to 90 minutes, with a call-out from £89 confirmed up front.
The mechanism is simple. 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.

On arrival in Southampton: what happens next
The drainer parks up, checks the vehicle has not been started and makes the area safe with cones and a drip tray. The fuel is pumped out through the filler or the fuel line into a sealed tank on the van, the lines are flushed, a few litres of the right fuel go in, and the engine is started and run until it idles cleanly. The contaminated fuel leaves with them.
What to ask on the phone before a drainer travels to Southampton
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Can you work on the forecourt, or does the car need to be moved?
- How long until you reach me in Southampton?
- Will you check the filter and pump if the engine ran?
- Do you take card payment at the roadside?
- What is the total, not just the call-out, if it is a straight drain?
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 Southampton.
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
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
Do you work at night in Southampton?
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.
How quickly can a drainer reach me in Southampton?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
