Drained where it stands **Short answer** The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Porthcawl Cardiff drains diesel in a petrol car on the spot, flushes through and refuels, typically in 45 to 90 minutes, with a call-out from £89 confirmed up front. The mechanism is simple. 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.

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.

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 Porthcawl Cardiff. 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 **How long does a drain take in Porthcawl Cardiff?** Usually 45 to 90 minutes on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank. **What does it cost in Porthcawl Cardiff?** 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. **Do you cover all of Porthcawl Cardiff?** Yes — forecourts, roadsides, homes and workplaces across Porthcawl Cardiff and the surrounding area. **Can I pay by card?** Yes. Card payment is taken on site once the job is done. **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. ### Who you are dealing with Wrong Fuel Drain is a brand of [Fuel Fixer Ltd](https://www.fuelfixer.co.uk/) (company number 08520551), a company of Fuel Fixer International, the multinational group behind this website.
