Chevron RPM Universal Gear Lubricants are multipurpose lubricants.

They are made from paraffinic base stocks and contain a carefully balanced additive package to provide maximum gear protection and long lubricant life. The sulfur-phosphorus extreme pressure additives used in Chevron RPM Universal Gear Lubricants provide superior thermal and oxidation stability.

In addition, this lubricant is fortified with rust and corrosion inhibitors, a foam inhibitor, and a pour point depressant.

It also contains a friction modifier that allows its use as a top-off lubricant in gear cases with limited-slip or positrack differentials.

The sulfur-phosphorus extreme pressure additives in Chevron RPM Universal Gear Lubricants reduce the spalling and wear of gears by creating a microthin sacrificial film on the surface of the gear teeth which is actually softer than the gears themselves. Frictional heat and pressures between tooth surfaces cause the sulfur-phosphorus to react with the surface of the gear teeth at the point of contact, thus creating the sacrificial film.

The highly refined base stocks and various inhibitors in the additive package assure a well-balanced lubricant and long gear and bearing life.

Applications

Chevron RPM Universal Gear Lubricants are recommended for use in all spiral bevel and hypoid differentials, power dividers, and oil-lubricated steering axle wheel bearings.

Their multiviscosity characteristics allow their use in equipment operating over a broad ambient temperature range. This means good cold flow properties and gear protection.

Chevron RPM Universal Gear Lubricants:

• meet the performance requirements of API Service Categories MT-1, GL-4 and GL-5
• are qualified for SAE J 2360 (formerly known as MIL-PRF-2105E)
• have Mack GO-J approval
• meet the requirements (discontinued in 1998) of the U.S. Department of Agriculture (USDA) for use in federally inspected meat and poultry plants as H2 lubricants with no food contact.
