Diesel in petrol in Keynsham? Drained where it stands
Before anything else, keep the key out of the ignition. A drainer covering Keynsham can be with you the same day for diesel in a petrol car, drain it where the car stands and have you moving in about 45 to 90 minutes. The misfuel call-out is £89 and the total is quoted on 01295 380724 before they travel.
A petrol engine lights its fuel with a spark, and diesel barely lights that way, so you get misfiring, smoke and eventually a car that will not start.

What the drainer does when they reach you in Keynsham
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.
What to ask on the phone before a drainer travels to Keynsham
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- How much more if the engine has already been started?
- Is there an extra charge at night or at the weekend?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- What is the total, not just the call-out, if it is a straight drain?
- How long until you reach me in Keynsham?
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 Keynsham.
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.
Can I pay by card?
Yes. Card payment is taken on site once the job is done.
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 work at night in Keynsham?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
