Petrol in diesel in Newquay? Drained where it stands
Put the keys in your pocket and ring 01295 380724. Petrol in a diesel car in Newquay is a drain-and-flush job done at the roadside, on the forecourt or on your drive — no tow, no garage. Call-out from £89, roughly 45 to 90 minutes on site, price agreed first.
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.

When a drainer arrives in Newquay
They bring the fuel. Once the tank is empty and the lines are flushed, the drainer adds enough of the correct fuel to get the engine running and to reach a filling station, then checks for warning lights before handing the keys back.
Questions worth asking before you book a drain in Newquay
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- How long until you reach me in Newquay?
- How much more if the engine has already been started?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- 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
- Leave the ignition alone — on many cars even unlocking it powers the fuel pump.
- Push the car clear of the pump if needed, with someone steering and the engine off.
- Call 01295 380724 and give the fuel, the amount and your exact location.
- Ask for the whole price, not just the call-out, and agree it.
- The drainer drains the tank into a sealed container and flushes the lines.
- Fresh fuel goes in, the engine is started and the waste fuel leaves with the drainer.

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 Newquay.
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
How quickly can a drainer reach me in Newquay?
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.
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.
Do you work at night in Newquay?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Can I drive to a garage with petrol in a diesel car?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
