What is equivalent to SAE 80 gear oil?
SAE 20 engine oil
Because the viscosity of gearbox and engine oils are measured on different scales, an SAE 80 gearbox oil is roughly equivalent in viscosity to an SAE 20 engine oil.
What is the GL rating on gear oil?
Gearbox oils are classified by the American Petroleum Institute using GL ratings. The higher an oil’s GL-rating, the more pressure can be sustained without any metal-to-metal contact taking place between transmission components.
What weight is GL-4 oil?
PennGrade 1® Multi-Purpose ‘Classic’ Gear Oil GL-4 SAE 80W-90 is recommended for use in such time-honored traditional manual transmissions as those made by Muncie, Rockwell, NVG/New Process, Borg-Warner, Saginaw and Ford as well as those used in many imports.
What viscosity is GL 4?

What is SAE 80?
SAE 80 is a non EP additive gear oil meeting the API performance level GL-1. It is blended from solvent refined paraffinic base oils. Suitable for gearboxes and some selected transmissions where a non EP gear oil is called for. For use in Passenger cars, towing vehicles, light commercial, and 4×4.
Is 80W the same as 10W 40?
The most common mistake is the belief that the viscosity of SAE 80W gear oil is much thicker than the viscosity of SAE 10W-40 motor oil. This is absolutely incorrect! A 10W-40 motor oil’s viscosity is actually similar to the viscosity of 80W gear oil, and the viscosity of SAE 10W-30 is similar to 75W gear oil.
Is gl4 synthetic?
Ultra1Plus™ SAE 75W-90 Synthetic Gear Oil, API GL-4 is formulated with synthetic base oils and specialty performance additives to provide improved high-temperature thermal and oxidative stability in a wide range of operating conditions.
What is 80w90 oil?
