Molybdenum Disulphide is the reason why CV joints now typically last the life of the vehicle, it is just about the slipperiest substance known to science, with fantastic performance on high pressure surfaces like cams and tappets ( and CV joints ). Most engines these days have MsO2 coated pistons to reduce friction ( not sure if Honda introduced it, but certainly among the first ). I have always added a glug of Moly to engines, some gearboxes like it, others don't ( certainly do not add it to CVT, where a controlled level of friction is required for box to operate ) even my motorbikes with wet clutches Liqui-Moly say 2% is OK, been using it for many years without clutch issues. I trust it will take care of cams and camchain / tensioner. A lot of the higher end oils already have Mso2 added. MsO2 has the property to stick to metals and form a tough layer, but not other stuff.
