Petrol in a diesel car in Tongwell Milton Keynes, drained on the spot
If the engine has not run, petrol in a diesel car in Tongwell Milton Keynes is usually a clean drain with no lasting harm. Keep it that way — don't start it — and ring 01295 380724. The call-out is £89, the drainer brings everything, and most jobs are done in 45 to 90 minutes.
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. That is why the ignition is the one thing not to touch.

What to expect from the drainer in Tongwell Milton Keynes
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
Before you agree a price: what to ask
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 check the filter and pump if the engine ran?
- 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?
- Do you bring clean fuel, and is it included?
- Is there an extra charge at night or at the weekend?
What to do right now
- Stop. Do not start the engine, even for a moment.
- Note the fuel type, the amount you put in and whether the car was already low.
- Ring 01295 380724 and give the location — a postcode or the filling station name is enough.
- Get the full price and an arrival time before you agree.
- A drainer attends, drains and flushes the fuel system where the car is parked.
- Clean fuel goes in, the engine is run, and you drive to the next forecourt to fill up.

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 Tongwell Milton Keynes.
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
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
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.
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.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
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.
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.
