Petrol in AdBlue tank in Sawston Cambridge? Drained where it stands

When a drainer arrives in Sawston Cambridge
On a forecourt the drainer will usually move the vehicle off the pump lane first, by hand, with the engine off. Then it is drain, flush, refuel and start. At home or at work they can do the whole thing on the drive or in the car park without moving it at all.
What to ask on the phone before a drainer travels to Sawston Cambridge
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Will you check the filter and pump if the engine ran?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Do you take card payment at the roadside?
- Is there an extra charge at night or at the weekend?
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.

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 Sawston Cambridge.
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
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
How long does a drain take in Sawston Cambridge?
Usually 1 to 3 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.
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.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
What does it cost in Sawston Cambridge?
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.
