What does EP stand for in gear oil?
What does EP stand for in gear oil?
The function of an extreme pressure (EP) additive is to prevent this adhesive wear and protect the components when the lubricating oil viscosity can no longer provide the necessary film thickness. How does it work? EP additives are polar molecules.
What is EP 80W-90 gear oil?
EP 80W-90 Gear Oil is a mineral oil based lubricant formulated for use in a wide range of automotive, plant, agricultural and industrial transmission systems. This grade has a high level of extreme pressure (EP) additive that provides effective gear protection over a range of temperatures and shock load conditions.
Is EP 90 the same as SAE 90?
When it comes to Gearbox oils, many older vehicles specified EP80 or EP90 weight oils. An SAE 90 gearbox oil is roughly the same viscosity as an SAE 50 engine oil. Most manufacturers now offer EP80W/90 oils in place of both EP80 and EP90.
What is an EP oil?
Classic Gear Oil EP 140 GL4 is an extreme pressure gear oil SAE 140 mineral based gear oil with performance additives. This product is engineered for gearboxes and differentials requiring EP lubricant to provide low friction and reduced noise.
Is it bad to mix gear oil?
Mineral oils, PAOs and esters may all be mixed together. Only polyglycol type synthetic oils (PG or PAG) may not be mixed with the other lubricant types. They can react together and form gum gels in the casings. Furthermore, they can sometimes be incompatible and immiscible with other polyglycols.

What is the difference between SAE and EP?
The higher the Extreme Pressure (EP), the higher the GL category is. It is important to know that the SAE Motor Oil Viscosity Chart (J300) is different from the SAE Gear Oil Chart (J306). The main difference between GL-4 and GL-5 gear oils is the amount of EP additives.
What is 90 ep gear oil?
Classic Gear EP 90 is a mineral SAE 90 transmission oil. The product is suitable for use in manual transmissions and other transmissions in classic vehicles that require a medium single-grade oil with extreme pressure protection that meets the API GL-4 specification.
What is EP 90?
Part.nr.: 34545. Classic Gear EP 90 is a medium SAE 90 transmission oil with extreme pressure protection for use in classic transmissions. The standards that modern lubricants are required to meet mean that modern-day transmission oils are often of low viscosity and are significantly less suitable, or unsuitable,…
What is gear lubricant?
Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It is of a high viscosity and usually contains organosulfur compounds.
