2 What is SpectraSyn Ultra PAO? An unique molecular structure which results in improved high viscosity, high VI PAO basestocks Provide more stable viscosity / film thickness vs. temperature profile, excellent shear stability, and lower traction Opportunities for Improved equipment protection at: High load H3C CH H2 C CH H2 C CH H2 C CH H2 C High temperature Low temperature H 2C CH 2 Reduced energy consumption from: Viscous churning CH3 CH3 CH3 CH3 CH3 Internal traction 2

6 Elastohydrodynamic Lubrication (EHL) Regime EHL occurs in rolling bearings, gears, and cams, where small contacts lead to very high local pressures (>1 GPa). Such high pressures cause the contacts to flatten elastically. In addition, lubricant viscosity increases exponentially with pressure and this allows a thin film (~1 µm) of lubricant to protect the surfaces. Under very thin EHL film conditions, the unique molecular structure of SpectraSyn Ultra provides a film thickness boost which reduces metal-to-metal contact and protects against wear. 6

7 SpectraSyn Ultra Improves EHL Film Thickness 1000 ISO VG 22 Synthetic Oil Lubricant film thickness as measured in a point contact (ball on disk) test rig demonstrates the benefits of SpectraSynTM Ultra Film Thickness (nm) ISO VG 22 with 2% SpectraSyn TM Ultra 150 ISO VG 22 with 0% Spectrasyn TM Ultra 150 Theoretical film thickness Speed (m/sec) SpectraSyn Ultra TM formulations provide additional film thickness thereby reducing friction, heat, and wear. Significance of enhanced EHL film thickness; Delays transition to boundary lubrication in valve train contacts Protects against wear by reducing local surface contact May also reduce boundary friction and 7 increase valve train efficiency

10 SpectraSyn Ultra PAOs have lower traction Maximum Shear Stress (psi) Lower Traction Maximum Contact Stress (psi) Scuffing Hypothesis: Scuffing occurs when Frictional Power Intensity (FPI) exceeds critical limit. FPI = (Traction)*(Power)*(V 2 -V 1 ) 2*A*λ 10 Note: Maximum shear stress is the maximum traction force divided by the contact area Mineral Oil Conventional PAO SpectraSyn Ultra PAO SpectraSyn Ultra - low traction may increase allowable gear loading / reduce scuffing & improve gear durability
