...unless it is cheap and you are rebuilding the engine anyways.

XcelPlus showed a similar reduction in friction (~30%):
Refer FAA testing
Fuel efficiency improvements will vary from car to car e.g.
Le Tourneau Uni testing +36%
If you want to experiment XcelPlus is a simple and cheap way of coating the moving parts in an engine.
