Komatsu Launches Sales of JASO DH-1 Certified Oil for the First Time from the Japanese Construction Equipment Industry

Komatsu Ltd. has led the Japanese construction equipment industry in employing high-performance oil that meets the JASO (Japan Automobile Standards Organization) DH-1 standard, and launched sales thereof as its genuine engine oil.

In April 2001, the Society of Automotive Engineers of Japan, Inc., in close collaboration with the Japan Automobile Manufacturers Association, Inc., the Petroleum Association of Japan and other organizations, specified the JASO DH-1 standards for engines made in Japan. This JASO DH-1 engine oil features higher performance in wear prevention, high-temperature oxidation stability and soot control and other properties than the conventional CD-class oil (equivalent to the former standard of the American Petroleum Institute) which is currently in wide use in Japan.

Komatsu has participated in the specification procedures of this new oil, and Komatsu�fs proprietary hot tube test (ability of hot surface deposit control is tested) has been employed as one of the DH-1 test standards.

Komatsu-genuine DH-1 series engine oil features outstanding levels of wear prevention, high-temperature oxidation stability, piston deposit and soot control based on Komatsu�fs own stringent specifications with the new addition of the JASO DH-1 standard. As a result, the new engine oil will extend the product life of engines and hydraulic components and reduce mechanical trouble as well as the consumption of engine oil and fuel. Komatsu believes that this new, high-quality oil will help customers reduce their total operating costs and facilitate their environmental conservation efforts.

Note: Starting with this series, Komatsu has changed the package design to this uniform visual identity for Komatsu-genuine engine oil.

While Komatsu is going to use this oil for Komatsu-made engines in factory, Komatsu Parts Ltd., a subsidiary, will aggressively market it as a Komatsu-genuine product. Komatsu will also work to expand worldwide sales through its own global networks.
