What drainers see in Castlerock
Most wrong fuel calls in Castlerock come from the forecourt itself, within a minute of the nozzle going back. The rest come from drivers who made it a mile or two before the engine note changed. Both are routine; the first is quicker.
The drain itself, step by step in Castlerock
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.
Five things to ask a drainer before they set off
You are going to pay for the job, so it is worth two minutes on the phone first. These are the questions that separate a straight quote from a surprise at the roadside.
- Do you take card payment at the roadside?
- Do you bring clean fuel, and is it included?
- 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?
- Is the vehicle over 3.5 tonnes, and does that change the price?
What drainers deal with in Castlerock
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

Where drainers work in Castlerock
Most drains in Castlerock happen on the forecourt where the mistake was made. The rest are at the roadside after the car cut out, or on a drive the next morning. All three work; the vehicle does not need to be towed anywhere.
Coverage takes in postcode district BT51 in Northern Ireland. If you are just outside, call anyway — the drainer covering the next area will usually come.

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 Castlerock.
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.
Does insurance cover petrol in a diesel car?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
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.
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.
