What Is AGMA 5 EP Gear Oil?

Agma 5ep gear oil is well prepared to tolerate very low pressures, temperatures, and environmental conditions compared to Synthetic ep gear lubricants.

These lubricants greatly enhance synthetic oils’ performance properties and contain additional extreme-pressure additives or EP additives. Also, these oils thus tend to work harder, last longer, and wear better than any other gear lubricant.

Some machines are not compatible with EP additives, so check the OEM specifications to determine before using the lubricant. However, here below we have described more information about this topic. Read on.

AGMA Gear Oil

AGMA industrial gear oil is a high-quality, high-pressure oil formulated for heavy-duty industrial gear lubrication. Furthermore, AGMA gear oils offer optimum load-carrying capability, oxidation resistance, and water separation.

What is AGMA 5?

AGMA 5 EP gear oil is specially designed for extreme pressure safety of medium to heavily loaded industrial gears and bearings. In particular, it’s mixed from PAO base stock which inherently provides good high and low-temperature protection. Designed for heavy-load industrial gear and bearing use.

AGMA 5 lubricant’s minimum viscosity and maximum viscosity are 198 mPa.s and 242 mPa.s. In addition, these numbers indicate the standard testing mechanisms used to determine how much resistance to flow these oils exhibit.

Extreme pressure is essential for tough industrial applications. Moreover, you can use this 5ep gear oil to lubricate industrial enclosed bearings & mining applications. Besides this, it’s suitable to use in Herringbone, Bevel & Spur Gears.

AGMA 5 EP Gear Oil Equivalent:

AGMA 5ep gear oil equivalent is an ISO VG 220 oil, AGMA 6 to ISO VG 320, AGMA 7 to ISO VG 460, etc. You may also see the letters S or EP associated with AGMA grades. This implies the requirement for synthetic (S) oil or oil designed with extreme-pressure (EP) additives.

SAE 50 Gear Oil Equivalent:

You can use Motul Classic SAE 50 low gear oil, and Vintage Miller 50 Monograde Oil as an equivalent of SAE 50 gear oil.

ISO 220 Gear Oil Equivalent:

ISO 220 gear oil is an industrial gear oil whose Kinematic Viscosity of 40°c is defined at 220 CST. AGMA 5 R&O gear oil is this oil’s North American counterpart. Alternatively, it identifies as AGMA 5ep extreme pressure gear oil. The automotive SAE 110 gear oil is also equivalent to ISO 220 gear oil equivalent.

Synthetic EP Gear Oil:

Synthetic EP Gear Oil is a synthetic liquid using PAO oil. This oil comes for extreme stress protection of medium to heavy-loaded industrial gears and bearings. Compared to transitional oil, it provides excellent oxidation life and lower temperature flow. Furthermore, it contains the ability to extend oil drain and enhance the component efficiency.

Applications of Synthetic EP Gear Oil:

Accordingly, this product can lubricate the industrial enclosed gear sets, roller, and heavy-loaded plains. This oil is suitable for anti-friction bearings, bevels, super gears, and industrial and mining applications.


  • Ability to extend oil drain compared to traditional oil because of better oxidation life
  • Able to enhance efficiency compared to traditional oils
  • Best for extreme temperatures
  • Amazing extreme pressure load and antiwear protection

Q. What is Agma 8 gear oil?

AGMA 8 ISO VG 680 compounded gear oils are commonly used in industrial worm gear drives. Generally, components need a thicker lubricant because of the gear teeth sliding action. Likewise, don’t contain extreme pressure additives that will cause premature wear of yellow metals.

Q. Which oil is best for gear?

There are many gear oils in the market. But choosing the best oil for your gear is very difficult. That’s why, before choosing the gear oil for your gear you should check your owner’s manual. Nonetheless, some of the best gear oils are:

  1. Quicksilver SAE 90 High-Performance Gear Lube
  2. Valvoline High Performance SAE 80W-90 Gear Oil
  3. Valvoline SynPower SAE
  4. Royal Purple Synthetic Manual Transmission Oil
  5. HONDA Professional Drive Shaft Oil
