Stationary Gas Engine Overview
• Generally very durable, robust designs
– Typically 40,000 hours between overhaulswith 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
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

Gas Engine Technology Performance & Approvals
– 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
No Industry-wide Specifications
Performance is determined by Extensive Field Testing

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 anti-
wear 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.
