Just for reference I have absolutely no idea if I can regain 1% of the losses between the engine and drive train friction by using Boron Nitride additives. It could be 0.5% or 2% gains or even a net 0. I'm simply suggesting there is likely a small benefit in recouping energy losses by reducing frictional due to the limits of motor oils boundary layer lubrication capabilities. Motor oil works best in hydrodynamic bearings not on cam lobes or chain guides. It does lybricate however its ability to reduce friction is far lower in those areas. In a hydrodynamic bearing (crank bearings) there is zero contact between metal parts. Thats why you can have cars with 100k miles on them, do a tear down and find stamping marks still legible on the bearing surface. Most metal in UOAs is from cam lobes, timing chains and Pistons/rings.
