Does it cost more if I started the engine?
It can. If the engine was run, the fuel has circulated and the job may take longer, and there's a risk of damage that needs a garage. Caught before starting, it's usually just the standard drain.
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.
