What does API GL-5 mean?
What does API GL-5 mean?
GL-5. Active. The designation API GL-5 denotes lubricants intended for gears, particularly hypoid (see note) gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions.
What does API GL-4 mean?
The designation API GL-4 denotes lubricants intended for axles with spiral bevel gears operating under moderate to severe conditions of speed and load, or axles with hypoid gears operating under moderate conditions of speed and load.
Can I use GL-5 instead of GL4?
Yes, you can use GL-5 gear oil instead of GL-4. The most important fact here is the API GL rating.
What is the difference between 75w90 and 80w90 gear oil?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.
What is the difference between API gl4 and gl5?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.

What is API GL 5?
The designation API GL-5 denotes lubricants intended for gears, particularly hypoid (see note) gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions. GL-6. Inactive. The designation API GL-6 denotes lubricants intended for gears designed with a very high pinion offset.
Is GL5 gear oil synthetic?
Bel-Ray® Synthetic GL-5 Gear Oil is designed to provide superb performance for automobiles, light and heavy duty trucks and various industrial equipment when API Service Classification GL-5 and/or MT-1 is specified. This product is formulated with synthetic base stocks that have outstanding thermal oxidation stability.
What is GL5 gear oil?
GL5 gear oil is a lubricant with very high extreme pressure performance needed for Hypoid gears where sliding and rolling contacts operate under very high loadings. This is achieved by incorporating high concentration of sulfurized additives.
