Common questions

Can I drive with the wrong fluid in the tank?

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 Milford Haven?

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 Milford Haven?

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 Milford Haven?

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.
