Wolf’s Head Extreme-Duty Mono-Grade Diesel Motor Oils are formulated for two-stroke diesel engines operating in severe service requiring highly effective control over cylinder and ring-face scuffing and deposits. They are designed to exceed the requirements of the API CF and CF-2 ratings. They are recommended for use in both on and off-highway applications where single grade heavy duty oils are specified. These oils provide excellent performance and reliability in older engines operating on high, medium, or low sulfur diesel fuel. Typical applications include older stationary and mobile equipment operating in mining, construction, farm, forestry, marine, and generator applications. Wolf’s Head Extreme Duty Mono-Grade Diesel Engine Oils are also an excellent fluid for various manual, semi-automatic, and power-shift transmissions where a fluid of this type is recommended.
Wolf’s Head Extreme-Duty Synthetic Blend Multi-Grade Diesel Motor Oils are premium high performance diesel engine oils utilizing the latest in engine oil additive technology to offer the ultimate protection of your engine. Designed to meet or exceed the latest OEM and API CK-4 requirements, they are also backwards compatible to previous OEM and API specifications such as CJ-4, CI-4, CI-4+, and CH-4. The 15W40 grade also carries the API SN classification for use in gasoline engines and is an excellent choice for operators with mixed fleets. These oils are specially designed to protect EGR/Low-Emission Diesel Engines while maximizing the durability of Diesel Particulate Filters (DPF’s). They are recommended for use in a wide range of heavy-duty applications and operating environments found on and off-highway, including engines operating under heavy loads. These oils offer extended service/extended drain when operated under typical operating conditions, improved TBN retention, lower oil consumption, greater wear protection, oxidation stability, excellent shear stability, and reduced high temperature deposits.
