GL-4 and GL-5 gear oils are utilized in a variety of conditions and applications. GL-4 is for hypoid gears used in open environments.
They are protected against rust, volatiles, and water/moisture by using GL-4 oil. GL-5 is intended for use in hypoid gearsets that run under harsh service and stress loading circumstances, as well as gearsets with a solid EP case for corrosion protection. GL-5 oils should not be used in a gearbox where the weather is monitored.
What Is API GL5 Gear Oil?
API GL5 Gear Oil is an advanced lubricant that helps the gears in your vehicle shift smoothly and effortlessly.
It is used in automatic and manual transmissions and is also a great lubricant for the gears in your vehicle’s engine.
API GL5 Gear Oil has a sulfur content that helps to reduce wear and tear on the gears while also providing protection against corrosion.
Additionally, API GL5 Gear Oil is formulated with zinc, which helps to improve gear performance and durability.
Is GL5 Full Synthetic?
GL5 is a fully synthetic lubricant, similar to other synthetic lubricants on the market. Synthetic lubricants are made from synthetic bases, which are made from petroleum.
They are generally considered to be safer than natural lubricants because they are not exposed to the elements and can thus last longer.
What Kind of Fluid Goes in A Front Differential?
A front differential is a type of differential that transfers power from the rear axle to the front axle. It does this by using a fluid to relay the power from the rear axle to the front axle.
