Unleaded in diesel in Croydon? Drained where it stands
Before anything else, keep the key out of the ignition. A drainer covering Croydon can be with you the same day for unleaded in diesel, drain it where the car stands and have you moving in about 45 to 90 minutes. The misfuel call-out is £89 and the total is quoted on 01295 380724 before they travel.
The mechanism is simple. Unleaded is petrol by another name, and in a diesel it strips the lubrication the injection pump depends on.

On arrival in Croydon: what happens next

Questions worth asking before you book a drain in Croydon
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Is there an extra charge at night or at the weekend?
- How long until you reach me in Croydon?
- Do you take card payment at the roadside?
- What is the total, not just the call-out, if it is a straight drain?
- Will you dispose of the contaminated fuel, and can I have a note of it?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

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 Croydon.
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
Do you work at night in Croydon?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
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.
Does insurance cover unleaded in diesel?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
What does it cost in Croydon?
The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels.
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.
Can I drive to a garage with unleaded in diesel?
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.
