6 PAO Key Features Compared to conventional mineral oils, PAOs have Higher viscosity index Lower temperature fluidity Lower volatility Better oxidative stability Greater thermal stability Lower traction force Compared to Group III oils, PAOs have Much wider viscosity range Slightly higher viscosity index PAO Lower temperature fluidity Similar or lower volatility Gp III Better oxidative and thermal stability Viscosity Range
7 Viscosity Index Viscosity change with Temperature PAO s typcially have a higher viscosity index than mineral oil. Lower viscosity at low temperature Offers increased fluidity. Mineral Oil PAO Viscosity Equivalent viscosity Higher viscosity at high temperature: Offers improved oil film thickness Temperature, o C

PAO withstands high temperatures with minimum decomposition.
17 Traction Maximum Shear Stress (psi) Lower Traction Maximum Contact Stress (psi) Note: Maximum shear stress is the maximum traction force divided by the contact area Mineral Oil Conventional PAO SpectraSyn Ultra PAO Scuffing Hypothesis: Scuffing occurs when Frictional Power Intensity (FPI) exceeds critical limit. FPI = (Traction)*(Power)*(V 2 -V 1 ) 2*A*λ The low traction of SpectraSyn PAOs may increase allowable gear loading / reduce scuffing & improve gear durability
