Abstract
Studies of selected automotive gear lubricants in heavy truck tandem axles and transmissions have revealed improvements in fuel economy associated with the viscosity of lubricants tested (grades 75W, 75W-90, and 80W-140). The testing included a heavy truck on-highway fleet test and test track operation.
Standard laboratory gear tests on light viscosity monograde (SAE 75W) oils indicate that oils of this type may be deficient in EP protection. Combined observations show that there may be a critical balance between axle lubricant fuel economy benefits and axle durability in field service.
