Yep its all written on can. Plenty of youtube vids too.

Can't remember the recommended interval but I only use it every 2nd service.

You should use the whole can though, half sits in before running, other half runs through at "idle", but you needto give it throttle as it will be hard to crank over and drop sharply when you spray it in.

**edit: yes do before oil change and Warm up motor beforehand.
