Gulf Harmony AW Hydraulic Oils Provide Superior Wear Protection; Outstanding Oxidative and Thermal Stability

View Our Gulf Lubricants Product LineGulf Lubricants / Nu-Tier Brands has received several inquiries regarding the topic of hydraulic oil service life determination by ASTM D 943 and oil service life of Gulf Harmony AW Hydraulic Oils. In response to these questions Gulf Lubricants has issued the following statement.

The purpose of running an ASTM D943 Oxidation Stability Test is to measure the resistance of a lubricant to oxidation, especially those lubricants prone to contamination by heat and water, hence a measure of its potential service life. Basically, in the ASTM D943 Oxidation Test, oxygen is bubbled through a sample of oil and water in the presence of a copper-steel catalyst while maintaining the sample temperature at 203°F. The time it takes to increase the Total Acid Number (TAN) of the sample to 2.0 mg KOH/g is indicative of the oil’s relative “oxidation lifetime”. The results are reported in hours.

Gulf Harmony AW Oils are excellent antiwear hydraulic oils formulated with high-quality base oils and fortified with additives that provide superior wear protection and outstanding oxidative and thermal stability. These oils have been tested and shown to provide outstanding ASTM D943 long life stability, typically in the 5000 to 6000 hour range for the lower viscosity fluids.

As of this writing, Gulf Harmony AW 68 has demonstrated +4000 hours while the AW 22, 32, & 46 are at 5500 hours and still running strong. These excellent numbers are a direct result of premium, clean base stocks and a well proven additive system.

In summary, Gulf Lubricants is dedicated to manufacturing and supply of high quality lubricants that conform to the most modern industry standards. These durable antiwear hydraulic oils are recommended for and will satisfy performance requirements by North American and European pump manufacturers.
