Presentation on the early stages of a lubricant optimisation programme from the MIT.
I'm impressed with the mid stroke viscosity optimisation concept to keep the viscosity up at the stroke ends (reduced boundary lubrication), while reducing the viscosity mid stroke where full hydrodynamic is in play.
Interesting (obvious 'though) on additive concentration in aras of oil volatising off...explains why volatility is important, and why the tests ARE representative of whathappens in an engine (hint, it's not about crankcase ventilation).
