The drain itself, step by step in Farnborough
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
Five things to ask a drainer before they set off
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Do you bring clean fuel, and is it included?
- How long until you reach me in Farnborough?
- Will you check the filter and pump if the engine ran?
- Is there an extra charge at night or at the weekend?
- Do you take card payment at the roadside?
What to do right now
- Don't press the start button or turn the key.
- Take a photo of the pump display: it shows the fuel type and the litres.
- Ring 01295 380724 and describe where the car is.
- Agree the price before booking — the call-out starts at £89.
- The drainer empties the tank and flushes the system where the car stands.
- They refuel, start the engine and check it before handing back the keys.

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 Farnborough.
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 I pay by card?
Yes. Card payment is taken on site once the job is done.
Do you work at night in Farnborough?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
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.
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
Do you cover all of Farnborough?
Yes — forecourts, roadsides, homes and workplaces across Farnborough and the surrounding area.
