Diesel in a petrol car in Braunston Northampton, drained on the spot
Stop, switch nothing on, and call 01295 380724. Local drainers across Braunston Northampton handle diesel in a petrol car every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 45 to 90 minutes on site and a call-out from £89, with the full price given before they leave for you.
What matters most is whether the fuel has moved beyond the tank. 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.

When a drainer arrives in Braunston Northampton
Expect a van with a pump and a sealed waste tank. The drainer drains the tank, flushes the system through, refuels with enough clean fuel to reach a forecourt, then starts the engine and lets it settle. You do not need a garage and the vehicle does not move until it is ready.
What to ask on the phone before a drainer travels to Braunston Northampton
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.
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Do you bring clean fuel, and is it included?
- Do you take card payment at the roadside?
- Is there an extra charge at night or at the weekend?
- 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 Braunston 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
Does insurance cover diesel in a petrol car?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
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.
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.
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.
