Diesel in gasoline in Portsmouth: a local drainer comes to you
If the engine has not run, diesel in gasoline in Portsmouth is usually a clean drain with no lasting harm. Keep it that way — don't start it — and ring 01295 380724. The call-out is £89, the drainer brings everything, and most jobs are done in 45 to 90 minutes.
The mechanism is simple. Gasoline is the American term for petrol. Diesel in a gasoline engine will not fire properly on the spark plugs.

What the drainer does when they reach you in Portsmouth
Expect a van with a pump and a sealed waste tank. The drainer drains the tank, flushes the system through, refuels with enough clean fuel to reach a forecourt, then starts the engine and lets it settle. You do not need a garage and the vehicle does not move until it is ready.
Before you agree a price: what to ask
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.
- Can you work on the forecourt, or does the car need to be moved?
- How long until you reach me in Portsmouth?
- What is the total, not just the call-out, if it is a straight drain?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
What to do right now
- Don't turn the key.
- Check what went in: the receipt and the pump number tell you the fuel and the litres.
- Call 01295 380724 with those details and your location.
- Get a price that covers the whole job, then book.
- The drainer arrives, drains the tank, flushes the lines and filter if needed.
- You get clean fuel, a running engine and a note of what was removed.

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 Portsmouth.
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
Does insurance cover diesel in gasoline?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
What does it cost in Portsmouth?
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.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
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.
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.
Can I drive to a garage with diesel in gasoline?
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.
