LE’s new PCMO Full Synthetic 5W-20 & 5W-30 Introduction LE’s new PCMO Full Synthetic 5W-20 & 5W-30 Available beginning March 15, 2012 Contains 100% Synthetic base fluids Optimized proprietary additive combination, including Monolec

Monolec® Tetra-Syn™ Engine Oil Introduction Monolec® Tetra-Syn™ Engine Oil Why Tetra? Definition: Means “four,” used in the formation of compound words Origin: Greek Performance | Protection | Endurance | Efficiency

Beneficial Qualities Performance Monolec Tetra-Syn Features 100% synthetic oil with proprietary additive package Exhibits low volatility and low viscosity shear characteristics Provides excellent low- and high-temp performance Exceeds performance criteria of API and most OEMs Outperforms commercially available PCMOs  

Beneficial Qualities Protection Monolec Tetra-Syn Reduces wear Ensures continuous flow of oil film with low-temp flow characteristics Isolates metal from rust and corrosion Provides superior oxidation protection Prevents formation of ash and other deposits, even in ring zones Protects from higher temps in engines with turbochargers and superchargers

Beneficial Qualities Endurance Monolec Tetra-Syn Safely extends drain intervals when combined with LE’s LEAP oil analysis program Extends oil service life Extends engine life  

Beneficial Qualities Efficiency Monolec Tetra-Syn Exceeds “Resource Conserving” guidelines for API SN engine oils Improves fuel economy in many newer engine configurations Lowers emissions and protects emission systems per API standards

Performance Claims Industry OEMs Monolec Tetra-Syn Performance Claims Industry API SN/SM/SL, ILSAC GF-5, and all preceding API & ILSAC gasoline categories Resource Conserving OEMs GM4718M, GM6094M & GM dexos 1™ performance requirements Ford WSS-M2C945-A (5W-20) Ford WSS-M2C946-A (5W-30) Others: Honda, Toyota, Chrysler, Nissan, Hyundai/Kia

Where Should It Be Used? Personal passenger cars Monolec Tetra-Syn Where Should It Be Used? Personal passenger cars Passenger car fleets (municipal, delivery, etc.) Offers exceptional performance suitable for use in most OEM gasoline engines, including: Honda, Ford, GM, Toyota, Chrysler, Nissan and Hyundai/Kia Consult your owner’s manual for details.
