Unleaded in diesel in Dorking: a local drainer comes to you
Keys out, bonnet shut, hazards on if you are at the roadside. Unleaded in diesel in Dorking 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.
Unleaded is petrol by another name, and in a diesel it strips the lubrication the injection pump depends on. That is why the ignition is the one thing not to touch.

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 Dorking.
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
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.

Do you cover all of Dorking?
Yes — forecourts, roadsides, homes and workplaces across Dorking and the surrounding area.
What does it cost in Dorking?
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.
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.
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.
