--- title: Wrong fuel in a Tesla — drain from £89 url: https://mis-fueldoctor.co.uk/vehicles/tesla/ focus: wrong fuel in a tesla phone: 01295 380724 updated: 2026-08-05 --- # Wrong fuel in a Tesla **Short answer** If the wrong fuel has gone into a Tesla, do not start the engine and call 01295 380724. Modern Tesla fuel systems use anti-siphon devices and baffled tanks, so the fuel cannot be removed with a hose — it needs specialist drainage equipment. A mobile technician attends where the vehicle stands, drains and flushes the system and refills with clean fuel, typically in 45 to 90 minutes, from just £89 misfuel callout fee. Caught before the engine runs, a Tesla misfuel almost never causes lasting damage.

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 the UK?** Most jobs fall between £89 and £1,500 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 the UK?** Yes. Mobile technicians attend forecourts, roadsides, homes and workplaces across the UK, 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.
