The appropriate lubricant for an automatic lubrication system can be determined using a Lincoln ventmeter. Factors such as the lubricant consistency, the diameter and length of the feed line and the operating temperature are taken into account. [7] The lubricant, be it oil or grease, is dispensed from a reservoir.
The NLGI consistency number is also a component of the code specified in standard ISO 6743-9 “lubricants, industrial oils and related products (class L) — classification — part 9: family X (greases)”. [1] The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.
Today, motor oil in the US is generally sold in bottles of one U.S. quart (950 mL) and on a rarity in one-liter (33.8 U.S. fl oz) as well as in larger plastic containers ranging from approximately 4.4 to 5 liters (4.6 to 5.3 U.S. qt) due to most small to mid-size engines requiring around 3.6 to 5.2 liters (3.8 to 5.5 U.S. qt) of engine oil.
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives. The lubricant is applied to a substrate by spray, dip or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases the wear life of the substrate to which it has been applied.

The Noack volatility test, named after Kurt Noack, [1] determines the evaporation loss of lubricants in high-temperature service. This test is standardized as ASTM D5800. [2] In this test, a sample is heated at 250 °C for 60 minutes with a constant flow of air over it. The weight fraction lost is the result for the Noack volatility test.
where U is the oil's kinematic viscosity at 40 °C (104 °F), Y is the oil's kinematic viscosity at 100 °C (212 °F), and L and H are the viscosities at 40 °C for two hypothetical oils of VI 0 and 100 respectively, having the same viscosity at 100 °C as the oil whose VI we are trying to determine.
The company was founded in 1986 by John Williams, a synthetic oil developer and later consultant. Due to a customer who said he had never seen purple oil, Williams named the product Royal Purple. [6] Producing synthetic oil using its own additives, [7] the company grew and in 2004 completed a 125,000 square foot production facility in Porter ...
