Petrol in a diesel car in Wembley: a local drainer comes to you
Before anything else, keep the key out of the ignition. A drainer covering Wembley can be with you the same day for petrol in a diesel 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.
Diesel lubricates the high-pressure pump as it passes through; petrol does the opposite and washes that film away, so the pump starts wearing within minutes of running.

What to expect from the drainer in Wembley
Most of the time is spent draining. A full tank of the wrong fuel takes longer to pump than a few litres, so the drainer will tell you roughly how long it will be once they see the gauge. After that it is a flush, a refuel and a test run before they leave.
What to ask on the phone before a drainer travels to Wembley
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- Is the vehicle over 3.5 tonnes, and does that change the price?
- 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?
- Do you take card payment at the roadside?
- How much more if the engine has already been started?
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 Wembley
Across Wembley, Greater London the common locations are the filling station itself, a lay-by a mile or two down the road, and home. If you are on a motorway hard shoulder, call the emergency services first; the drainer can meet you once the vehicle is somewhere safe.
If you are just outside Wembley, you are probably still in range: Wembley Park, Tokyngton, Preston and Wembley Central are all covered by the same drainers.

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 Wembley.
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 I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
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.
What does it cost in Wembley?
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.
Do you cover all of Wembley?
Yes — forecourts, roadsides, homes and workplaces across Wembley and the surrounding area.
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.
