Red diesel in tank in Barnet? Drained where it stands
Leave the engine off. With red diesel in the tank in Barnet, 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 1 to 2 hours, and you hear the full price before anyone sets off.
Mechanically red diesel runs, but in a road vehicle it is a duty offence; the tank is drained, flushed and the fuel disposed of under licence. That is why the ignition is the one thing not to touch.

On arrival in Barnet: what happens next
Most of the time is spent draining. A full tank of the wrong fuel takes longer to pump than a few litres, so the drainer will tell you roughly how long it will be once they see the gauge. After that it is a flush, a refuel and a test run before they leave.
Five things to ask a drainer before they set off
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- How long until you reach me in Barnet?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- What is the total, not just the call-out, if it is a straight drain?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
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.

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 Barnet.
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
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.
How long does a drain take in Barnet?
Usually 1 to 2 hours on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
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.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
Do you cover all of Barnet?
Yes — forecourts, roadsides, homes and workplaces across Barnet and the surrounding area.
