Why I Believe SAE 80 API GL 4 Hypoid Gear Oil is Necessary

As a car enthusiast and an experienced mechanic, I have come to understand the importance of using the right type of gear oil for vehicles. And when it comes to hypoid gear oil, there’s no doubt that SAE 80 API GL 4 is necessary for optimal performance and longevity of a vehicle’s drivetrain.

Firstly, SAE (Society of Automotive Engineers) has set specific standards for gear oils based on their viscosity and performance. In simple terms, viscosity refers to the thickness or flow rate of the oil. And for hypoid gears, which operate under high pressures and extreme temperatures, a thicker oil like SAE 80 is essential to prevent metal-to-metal contact and reduce wear.

Moreover, API (American Petroleum Institute) has also established its own classification system for gear oils based on their load-carrying capacity and anti-wear properties. The GL (Gear Lubricant) rating indicates that the oil contains additives that provide protection against extreme pressure and wear. And with a rating of GL 4, SAE 80 API gear oil is specifically designed for hypoid gears that experience moderate to high loads.
