[QUOTE="Emmerson_Biggins, post: 1860650, member: 13722"] No offense taken, and your points are principled. If I have a higher viscosity, the oil has a resistance to flow, therefore it takes more mechanical energy to move high viscosity oils from in between two surfaces. If the contray were true as you propose, then 0w oil would be perfect for use in a rear diferential instead of GL-5. The ability to build a satisfactory hydrodynamic wedge also increases with viscosity, albeit at a cost. Too much viscosity can wash out the bearings, wearing the babbit right off their surfaces, for that reason I do not condone the use of 50 weight oil in an engine such as this that was not designed for it. On the note of a pre-oiler, anytime you can start a car that already has oil pressure, you are time and money ahead. Good Show!!! Please feel free to re-state your opinions or redirect if appropriate. [/QUOTE]
