Petrol in a diesel car in Daventry Northampton: a local drainer comes to you
Keys out, bonnet shut, hazards on if you are at the roadside. Petrol in a diesel car in Daventry Northampton is drained on site by a local drainer: pumped out, flushed and refilled in about 45 to 90 minutes. Call-out from £89 — call 01295 380724 and you get the figure before anyone drives to you.
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 Daventry Northampton: 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.

- Will you dispose of the contaminated fuel, and can I have a note of it?
- Can you work on the forecourt, or does the car need to be moved?

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 Daventry Northampton.
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 my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
Do you cover all of Daventry Northampton?
Yes — forecourts, roadsides, homes and workplaces across Daventry Northampton and the surrounding area.
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.
How quickly can a drainer reach me in Daventry Northampton?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
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.
