What is equivalent to SAE 90 gear oil?
SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want.
What is the viscosity of 80W-90 gear oil?

What viscosity is gear oil?
The viscosity of synthetic oils according to the ISO grading system is between 32 to 6800. Synthetic gear oils are used for gears operating under extreme conditions: very low or very high temperatures, high pressures.
What’s the difference between 75 90 and 80W 90 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.
Is 80W 90 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!
What kind of lubricant is gear oil 90?
Gear Oil SAE 90 API GL-4 & GL-5 are lubricating gear oils for mechanical transmissions based on high quality base oils and additives that are a balanced combination of active ingredients. High pressure agents and other additives offer good wear protection under harsh operating conditions.
What are the grades of SAE engine oil?
Automotive Lubricant Viscosity Grades: Engine Oils – SAE J 300, Dec. 1999 SAE Viscosity Grade [°C] Min. Viscosity [mm²/s] at 100 °C Max. Viscosity [mm²/s] at 100 °C High Shear Rate Viscosity [mPa.s] at 150 0W 3.8 — — 10W 4.1 — — 15W 5.6 — — 20 5.6 <9.3 2.6
What kind of additive is gear oil GL-5?
Gear Oil GL-5 are multipurpose lubricants. They are made from paraffinic base stocks and contain a carefully balanced additive package to provide acceptable market general gear protection and lubricant life. The sulfur-phosphorus extreme pressure additive technology used in Gear Oil GL-5 provides good thermal and oxidation stability.
What kind of lubricant does synpower 75W90 use?
