On arrival in Gabalfa Cardiff: what happens next
The job is quieter than people expect. Tank drained into the van, lines flushed, clean fuel added, engine started and watched for a few minutes. The waste fuel is logged and taken for licensed disposal, and you get a receipt showing what was done.
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.
- How much more if the engine has already been started?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- Will you check the filter and pump if the engine ran?
- Do you bring clean fuel, and is it included?
- What is the total, not just the call-out, if it is a straight drain?
What to do right now
- Stop. Do not start the engine, even for a moment.
- Note the fuel type, the amount you put in and whether the car was already low.
- Ring 01295 380724 and give the location — a postcode or the filling station name is enough.
- Get the full price and an arrival time before you agree.
- A drainer attends, drains and flushes the fuel system where the car is parked.
- Clean fuel goes in, the engine is run, and you drive to the next forecourt to fill up.

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 Gabalfa Cardiff.
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 you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
Do you work at night in Gabalfa Cardiff?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
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.
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.
