It seems like you're asking about a specific type of gear oil: EP 80W90 GL-5 from the brand "Gear Guard." Gear oils are lubricants specifically designed for use in various types of gears, such as manual transmissions, differentials, and other gear-driven components in vehicles and machinery.

Here's what the information you provided means:

EP 80W90: This refers to the viscosity and temperature characteristics of the gear oil. "EP" stands for Extreme Pressure, indicating that the oil is formulated to handle high-pressure conditions often found in gear systems. "80W90" represents the viscosity grade of the oil. The "80" indicates the viscosity rating of the oil at lower temperatures (winter or cold conditions), and the "90" indicates the viscosity rating at higher temperatures (summer or hot conditions).
GL-5: This is a gear oil classification system set by the American Petroleum Institute (API). GL-5 oils are designed to provide high levels of protection against extreme pressure and wear in hypoid gears, which are commonly found in automotive differentials.
Brand: Gear Guard: "Gear Guard" is the brand or manufacturer of the gear oil. Brands often have their unique formulations and additives that cater to specific performance requirements.
EP 80W90 GL-5 gear oil is commonly used in manual transmissions, differentials, and other gear applications in vehicles. It provides excellent protection against wear, oxidation, and corrosion, ensuring the smooth operation and longevity of gear components.

When choosing a gear oil, it's essential to follow the manufacturer's recommendations and requirements for your specific vehicle or machinery. Different applications may have varying demands, and using the right type of gear oil is crucial for optimal performance and durability.
