What is Universal Tractor Lubricant

Universal Tractor Lubricant is actually a multi-purpose lubricant. In addition to lubricating tractor hydraulics, it is also used in the PTO (power take off), transmission, steering and wet brake systems of tractors.

How much oil do you need?

Equipment specifications and capacities vary. Consult your owner’s manual or contact your manufacturer for specific requirements for your machinery.

Buying in larger quantities may be beneficial for one or more of the following reasons:

  • You have more than one piece of equipment that requires the same lubricant.
  • You want to have additional lubricants on hand.
  • Purchasing a larger quantity gives you a price break.

Frequently asked questions

What lubricant should I buy?

Consult your owner’s manual for details. If you don’t have an owner’s manual, check with your dealer or manufacturer for recommendations.


When should lubricants be changed?

Lubricants should be changed according to manufacturer’s recommendations. Frequent oil changes help your engine by:

  • Minimizing wear and tear
  • Providing corrosion protection
  • Cooling the engine
  • Removing contaminates

What is viscosity?

Viscosity is the lubricant’s resistance to flow. All lubricants tend to undergo changes in viscosity at different temperatures. Lubricants thicken in cooler temperatures and thin out in higher temperatures.


What are multigrade lubricants?

Multigrade lubricants are ideal to meet a variety of temperature requirements. Multigrades have a dual viscosity designation, such as 10W-30. 10W defines the viscosity at 0 degrees F (hence the W, for “winter”) and 30 defines the viscosity at operating temperatures. You may also hear viscosity numbers referred to as “weights.”


What are additives?

Additives include the following:

  • Detergents, which keep surfaces of your engine clean, and
  • Dispersants, which disperse solid particles so they don’t come together to form sludge, varnish, and acids.
