The most critical component is the EP additive, which contains compounds like sulfur or phosphorus. Maintenance Best Practices and Selection.
What 80/90 Gear Oil Viscosity Numbers Actually Mean
Decoding the Numbers: What 80/90 Actually Means The numbers assigned to gear oils are not arbitrary; they are a standardized measurement of viscosity, or resistance to flow, defined by the Society of Automotive Engineers (SAE). Choosing the right specification ensures that gears remain protected under the extreme pressures they endure during operation.
These additives include antioxidants to prevent thermal breakdown, rust inhibitors to protect metal surfaces, and foam suppressors to maintain consistent lubrication. At lower temperatures, such as a cold morning, the oil flows readily with an SAE 80 viscosity, ensuring quick lubrication during startup when metal parts are most vulnerable.
Decoding 80/90 Gear Oil Viscosity Numbers and Their Meaning
This dynamic behavior is achieved through the inclusion of viscosity index improvers that expand the lubricant’s effective temperature range. Compatibility with Modern Vehicles Owners of modern vehicles might wonder if this decades-old specification has a place in today’s market.
