Chevron Delo Gear Lubricants ESI are premium grade, multipurpose gear lubricants.

They are formulated with ISOSYN® base stocks and compounded with a unique extreme pressure additive utilizing an inorganic borate compound. They also contain a patented, synergistic combination of additives that protect against wear, seizure, oxidation, corrosion, rust, and foam.

Chevron Delo Gear Lubricants ESI are ideally suited for gear sets exposed to extremely high temperatures and loads.

Tests have proven that Chevron Delo Gear Lubricants ESI provide a wear protection film 3 to 5 times thicker than the conventional sulfur-phosphorus antiwear film. The inorganic borate film is composed of compounds that do not react with metal. The film forms promptly to provide superior gear protection and improved thermal stability. By minimizing friction, cooler operating temperatures have been observed.

Applications

These lubricants are excellent for all types of automotive and industrial bearings and gears, particularly those operating under severe temperature and load conditions. They provide excellent wear control even in the presence of small amounts of water. Their exceptional thermal and oxidation stability, and antiwear performance permit longer gear life and extended drain intervals.

Chevron Delo Gear Lubricant ESI SAE 80W-90 is the first nonsynthetic gear oil approved for the extended warranty program of Dana Spicer heavy duty axles and is an approved lubricant for drive axles under the Eaton Roadranger E500™ Extended Warranty Program. Chevron Delo Gear Lubricants ESI are also approved for the extended drain specifications of both ArvinMeritor and Mack.
