Harley Evo 1/5th scale Preserving cam area with grease Microcosm R33

This Microcosm R33 1/5 scale Harley Evo runs great. It's worn in and required a very slight tweak to valve clearances. Now it runs perfect and I don't want any more cam or cam follower wear. I have it on good authority from channel friends commentary that "Marvel Mystery Oil" in the fuel tkes care of this elegantly, but I don't have...yet. Will use grease with a bit of oil. This is a great idea for any of these Chinese semi-scale models and vintage models which don't have cams and cam followers designed for long use.
