Red diesel in tank in Portishead? Drained where it stands
If the engine has not run, red diesel in the tank in Portishead 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 1 to 2 hours.
Mechanically red diesel runs, but in a road vehicle it is a duty offence; the tank is drained, flushed and the fuel disposed of under licence. That is why the ignition is the one thing not to touch.

What to expect from the drainer in Portishead
A good drainer asks three questions before touching anything: what fuel went in, how full the tank is, and whether the engine was started. The answers decide whether it is a straight drain or a drain plus a flush of the filter and pump. Either way it happens where the vehicle is parked.
Questions worth asking before you book a drain in Portishead
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- Do you bring clean fuel, and is it included?
- Can you work on the forecourt, or does the car need to be moved?
- What is the total, not just the call-out, if it is a straight drain?
- How long until you reach me in Portishead?
- Do you take card payment at the roadside?
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.

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 Portishead.
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
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.
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.
Do you cover all of Portishead?
Yes — forecourts, roadsides, homes and workplaces across Portishead and the surrounding area.
What does it cost in Portishead?
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.
Does insurance cover red diesel in the tank?
Many policies exclude misfuelling. Some breakdown cover and optional add-ons include it. Check your policy wording before assuming either way.
