I started the engine after putting the wrong fuel in — what now?

Stop driving and switch off as soon as it's safe. Running the engine circulates the wrong fuel, but a prompt drain and flush still prevents most damage in the majority of cases. Call for a drain rather than continuing to drive.

In an emergency: don't start the engine and call 0800 170 0644. We drain the wrong fuel on-site, 24/7, 365 days a year.
