-> Has anyone used these ideas before?
Yep!
-> Did they work?
Nope.
-> What type of oil should I use?
Cheap.
Good luck.  Don't hold your breath though.
Stuck engines from disuse can benefit from such treatment. Stuck engines
from MISuse generally don't.  Engines that have siezed from lack of oil
NEVER, in my experience.
