At home or at work they can do the whole thing on the drive or in the car park without moving it at all. ## 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. - Is there an extra charge at night or at the weekend? - 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? - 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? ## 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.

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 **Does insurance cover unleaded in diesel?** Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way. **Can I pay by card?** Yes. Card payment is taken on site once the job is done. **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. **What if I have already driven home?** Leave it on the drive with the engine off and call 01295 380724. The drainer can do the whole job at your house. **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. **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. ### Who you are dealing with Wrong Fuel Drain is a brand of [Fuel Fixer Ltd](https://www.fuelfixer.co.uk/) (company number 08520551), a company of Fuel Fixer International, the multinational group behind this website.
