Diesel in a petrol car in Andover: a local drainer comes to you
Stop, switch nothing on, and call 01295 380724. Local drainers across Andover handle diesel in a petrol car every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 45 to 90 minutes on site and a call-out from £89, with the full price given before they leave for you.
What matters most is whether the fuel has moved beyond the tank. A petrol engine lights its fuel with a spark, and diesel barely lights that way, so you get misfiring, smoke and eventually a car that will not start.

What the drainer does when they reach you in Andover
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.
What to ask on the phone before a drainer travels to Andover
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.
- Do you bring clean fuel, and is it included?
- What is the total, not just the call-out, if it is a straight drain?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Is the vehicle over 3.5 tonnes, and does that change the price?
- How long until you reach me in Andover?
What to do right now
- Keep the engine off and put the keys somewhere you will not absent-mindedly use them.
- Move the car only by pushing, with help, and only if it is blocking a pump.
- Phone 01295 380724 and describe what happened.
- Confirm the quote — call-out from £89 — and the arrival window.
- The drainer empties the tank into a sealed container and flushes through.
- After a refuel and a test run, the waste fuel leaves with the drainer for licensed disposal.

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 Andover.
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
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
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.
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
Can I drive to a garage with diesel in a petrol car?
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.
Do you work at night in Andover?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
