Gasoline in diesel in Guildford, drained on the spot
Leave the engine off. With gasoline in diesel in Guildford, the fix is a local drainer who comes to the vehicle, pumps the tank out, flushes the lines and puts clean fuel in. Call 01295 380724: the call-out starts at £89, the job usually takes 45 to 90 minutes, and you hear the full price before anyone sets off.
Here is why it matters. Gasoline is petrol. In a diesel engine it thins the fuel and takes away the lubrication the pump and injectors need.

What the drainer does when they reach you in Guildford
First they confirm what went in and how much, and whether the engine ran — that decides how far they need to go. Then the tank is emptied into a sealed container, the fuel lines and filter are flushed where needed, clean fuel is added and the vehicle is started and checked before they sign it off.
What to ask on the phone before a drainer travels to Guildford
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.
- Do you bring clean fuel, and is it included?
- Can you work on the forecourt, or does the car need to be moved?
- How long until you reach me in Guildford?
- Do you take card payment at the roadside?
- Is the vehicle over 3.5 tonnes, and does that change the price?
What to do right now
- Keep the engine off and put the keys somewhere you will not absent-mindedly use them.
- Move the car only by pushing, with help, and only if it is blocking a pump.
- Phone 01295 380724 and describe what happened.
- Confirm the quote — call-out from £89 — and the arrival window.
- The drainer empties the tank into a sealed container and flushes through.
- After a refuel and a test run, the waste fuel leaves with the drainer for licensed disposal.

Forecourt, roadside or drive: where we drain in Guildford
Most drains in Guildford happen on the forecourt where the mistake was made. The rest are at the roadside after the car cut out, or on a drive the next morning. All three work; the vehicle does not need to be towed anywhere.
The drainers who cover Guildford also work Onslow Village, Worplesdon, Christmas Pie and Flexford, so a call from any of them is handled the same way.

From the drainer's notebook
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.
Common questions
How long does a drain take in Guildford?
Usually 45 to 90 minutes on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
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.
Do you work at night in Guildford?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
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.
Does insurance cover gasoline in diesel?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
