2 Agenda Natural Gas Stationary Engines Types/Applications Vehicular Engines Types/Applications OEMs and Approvals Summary Open Discussion

3 Stationary Gas Engine Overview Generally very durable, robust designs Typically 40,000 hours between overhauls with quality engine oils Engines rebuilt many times Engine reliability important to customer Generally operate at Constant speed High, continuous load Come in all power ranges 100 kw to 16 MW Most common application ~1 MW Typical cost ~1+ MM U.S. dollars

4 Why do gas engines need special oils? Because the engines run on methane gas! The engines often generate severe oil stress Gas burns very hot (cogeneration engines run even hotter) Engines run at high load (often above full rated load) Stationary engines are often in remote operations Oxidation control is important, especially in 4-cycle applications Natural gas usually contains no sulfur Less TBN is required Gas is dry Oil ash controls valve wear in 4-cycle engines Minimum ash level is required for 4-cycle application Ash deposits can lead to pre-ignition or port plugging Ash level must be optimized for 4-cycle applications Ashless oils are required for 2-cycle application

5 Recoverable Shale Gas in the U.S.

6 Horizontal Wells + Hydraulic Fracturing

7 NGEO Applications From the Wellhead to the Powerplant Application Wellhead Gathering Gas Processing Plants Gas Pipelines / Compressor Stations Residential Electric Power Plants Industrial Electric Power Plants Natural Gas Vehicles Typical Natural Gas Engine Type 4-cycles with some 2-cycles Large 2-cycles / large 4-cycles Large 2-cycles / large 4-cycles / Turbines Large 4-cycles / Turbines Large 4-cycles / Turbines Mobile CNG / LNG engines

8 America Main Gas Engine Builder Caterpillar, Waukesha, GE Jenbacher, Cummins, Europe Detroit / Volvo, Dresser Rand, Cooper Compression, Wärtsilä. GE Jenbacher, Waukesha, Caterpillar, MWM (Deutz Power Systems), Wärtsilä, Rolls Royce, Guascor, MDE/MTU, MAN. Asia Caterpillar, GE Jenbacher, Weichai, Yammar, Komatsu, Waukesha, Wärtsilä.

9 Gas Engine Technology Performance & Approvals No Industry-wide Specifications No universal industry performance specifications as with Automotive Oils Most OEMs place the responsibility for oil selection and performance on the oil supplier Most OEMs have established oil selection guidelines Chemical and physical properties Proven field service Many OEMs have approval processes or recommend oils by brand name Performance is determined by Extensive Field Testing

10 RUGGED NATURAL GAS ENGINE OIL Rugged Natural Gas Engine Oil is a premium quality, dispersant-detergent natural gas engine oil designed for use in mobile equipment. The formulation is low-ash and features excellent antiwear properties to protect pistons, liners and valve-trains against excessive wear. It provides outstanding performance in transit, school and delivery fleets powered by Detroit Diesel, Cummins or John Deere CNG or LNG engines in both normal and extended drain service intervals. Rugged Natural Gas Engine Oil possesses excellent oxidation and nitration resistance, as well as outstanding protection against wear, rust, corrosion, foaming and aeration. APPLICATIONS: Transit buses School buses Delivery trucks Equipment with CNG or LNG engines SPECIFICATIONS: Cummins CES Detroit Diesel Company 93K216 Volvo CNG Renault RGD Mercedes Benz DC API CF-4 Endorsements: Mack endorses this specific formulation A SUPERIOR PRODUCT BY COLORADO PETROLEUM TH TYPICAL PROPERTIES 15w40 Specific 60 F 0,876 Flash (COC), C ( F) 228 (440) Pour Point, C ( F) -36 (-33) Viscosity, Kinematic C 114 C 15.2 Viscosity Index 139 Total Base Number (TBN), ASTM D Sulfated Ash, ASTM D874, wt %.77 Phosphorus, wt % 0.08 Zinc, wt % Cold Cranking Viscosity, -20 C 6,300
