Abstract
A gear lubricant field test in 32 new Class 8 vehicles totaling over 2 million miles (3.2 million kilometers) determined that one lubricant compounded with a potassium borate additive can be used in both axle and transmissions, providing a 3.5% benefit in fuel economy compared to conventional lubricants. while giving superior wear protection and oxidation stability.
