Unleaded in diesel in Guildford? Drained where it stands
Keys out, bonnet shut, hazards on if you are at the roadside. Unleaded in diesel in Guildford 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.
What matters most is whether the fuel has moved beyond the tank. Unleaded is petrol by another name, and in a diesel it strips the lubrication the injection pump depends on.

What to expect from the drainer in Guildford
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.
What to ask on the phone before a drainer travels to Guildford
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.
- Do you take card payment at the roadside?
- How much more if the engine has already been started?
- How long until you reach me in Guildford?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Can you work on the forecourt, or does the car need to be moved?
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 Guildford.
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.
