What to do right now

  1. Do not turn the key or start the engine — that is what turns a drain into a repair.
  2. Do not move the vehicle. On a forecourt, apply the handbrake and tell the station staff.
  3. Call 01295 380724 with your location, your vehicle and which fuels were mixed. You get the price before we set off.
  4. A technician attends with a licensed drainage unit and makes the area safe.
  5. The contaminated fuel is pumped out and the fuel lines are flushed through.
  6. Clean fuel goes in, the vehicle is started and checked, and you drive away. The waste fuel leaves with us for compliant disposal.

Where we attend around Neath

We attend right across postcode districts SA10, SA11 and the roads linking them, including the Neath post town area of Neath Port Talbot. the M4, A465 Heads of the Valleys and A4107 are the main routes in, and the steelworks, the valley roads and the M4 junctions are familiar ground. Wherever the vehicle stopped, that is where it gets drained. Give your postcode on the phone for a price and an arrival window before a technician leaves.

How serious is it?

It sounds like a disaster and usually is not. The tank is drained, the lines flushed, clean fuel added, and the car runs as before. Mileage driven on the wrong fuel is what changes that.

What happens when we arrive

Everything happens at the kerbside in Neath: extraction into a sealed drum, a flush of the feed lines, a refill with the correct grade, and a check that the engine idles and pulls away cleanly.

Common questions

Can I drive with wrong fuel?

No. Starting or driving pumps it through the system and can turn a straightforward drain into an expensive repair. Leave the vehicle where it is and call 01295 380724.

How long does the drain take in Neath?

About 45 to 90 minutes on site once the technician arrives. Vehicles that were started or driven take longer, because the lines and filter need flushing as well as the tank.

How much does it cost in Neath?

Most jobs fall between £199 and £1,999 depending on the vehicle, how much wrong fuel is in the tank and whether the engine was started. You get the price on the phone before we travel.

Will it have damaged the engine?

Only if it has been run through the system. Caught before starting, it sits in the tank and a drain removes it cleanly.

Does insurance cover it?

Often not. Most car insurance policies exclude misfuelling as standard, though some breakdown policies and optional add-ons include it. Check your own wording.

Do you cover rural and island Neath?

Yes. Technicians attend forecourts, roadsides, homes, farms and workplaces across Wales, including the uplands and the islands. Remote jobs are quoted with travel included so the price does not move.
