What to expect from the drainer in Johnstone
First they confirm what went in and how much, and whether the engine ran — that decides how far they need to go. Then the tank is emptied into a sealed container, the fuel lines and filter are flushed where needed, clean fuel is added and the vehicle is started and checked before they sign it off.
What to ask on the phone before a drainer travels to Johnstone
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- Do you bring clean fuel, and is it included?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Is there an extra charge at night or at the weekend?
- Can you work on the forecourt, or does the car need to be moved?
- How much more if the engine has already been started?
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 Johnstone.
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
How quickly can a drainer reach me in Johnstone?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
How long does a drain take in Johnstone?
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.
Can I drive to a garage with petrol in the adblue tank?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
Will the car need a service afterwards?
Not after a straight drain. If the engine ran on the wrong fuel, the drainer will tell you whether the filter should be changed.
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.
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.
