Swansea [Gorseinon Swansea wrong fuel cover](/areas/gorseinon-swansea/)[Petrol in a diesel car explained](/petrol-in-diesel/) ## Common questions **Can I drive with petrol in a diesel car?** 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?** 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 Gorseinon Swansea?** The call-out is £89–£199 and the drain £199–£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 anyone travels. **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 Gorseinon Swansea?** Yes. Mobile technicians attend forecourts, roadsides, homes and workplaces across Gorseinon Swansea, 24 hours a day. ### Who you are dealing with Misfuel Doctor 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.
