Universal Lubricants, Inc. strives to provide customers with the highest quality products available. Dyna-Plex 21C Durazol HC Engine Oil and Dyna-Plex 21C Cursa Hydraulic Oil utilize new hydrocracked base oils and proprietary additive technology to provide exceptional oxidation stability under conditions which lead to thermal breakdown.

Oxidation stability is a key property of a lubricating oil which determines its service life in an engine or hydraulic system. Everything exposed to oxygen in the earth's atmosphere oxidizes; metal rusts, people age, fuel burns. Lubricating oils oxidize at operating temperatures by a chemical reaction with oxygen that, over time, results in the formation of sludge and acids, increases in viscosity, reduced ability to handle contaminants and decreases in filterability. In other words, the lubricating oil has lost its ability to perform key functions and should be changed.

Many of today's equipment operators have expressed an interest in the extension of lubrication service intervals without sacrificing equipment life. This results in a tremendous savings in maintenance costs because of fewer oil/filter changes over the life of the equipment and the corresponding gain in production from the equipment up-time. The key to achieving extended drains is superior oxidation resistance of the lubricating oil.

Durazol HC Engine Oil and Cursa Hydraulic Oils incorporate exclusive, proprietary additive technology with the very highly refined hydrocracked base oils (Group II base oils as defined by API). These new base oils are processed at high temperatures and pressures to remove all of the sulfur, nitrogen and oxygen compounds that remain from the solvent extraction processes that predominate lubricating base oil refining in the United States. These severe processing conditions also saturate all of the aromatic compounds that are the precursors for oil sludge. The hydrocracked or Group II base oils are "water white" or clear in color.

With the elimination of these potentially "bad compounds" in the lubricating oil, it is possible to formulate engine and hydraulic oils with oxidation stability equal to or greater than that for products based on 100% synthetic oils. However, the costs and resulting finished product prices are lower for the Durazol HC and Cursa oils using the hydrocracked or Group II base oils.

In summary, Universal Lubricants, Inc. utilizes engine and hydraulic oil technology which provides exceptional oxidation stability. With this level of performance, further extension of oil service intervals is readily obtainable with the use of Dyna-Plex 21C Durazol HC Engine Oil and Dyna-Plex 21C Cursa Hydraulic Oil. Universal's Engine Guard™ Used Oil Analysis Program is available to customers at no charge. The trained staff at our in-house laboratory will assist in monitoring interval extension for maximum benefit without danger to equipment.
