Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.
Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.
The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1] [2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades. The requirement was added after the winters of 1980-81 and 1981-82 caused major ...
The cold-cranking simulator (CCS) is a device used to determine the low temperature performance of lubricants, when starting a cold engine (i.e. cold-cranking).In this condition, the only energy available to turn the engine comes from the starter motor and the battery, and it has been widely assumed that the system acts as a constant power viscometer.
Over the years, the Mobil Oil Corporation sponsored many Mobil Economy Run events across the country for various car classes and automobile associations for short distances. [6] In 1963, a "day-day" test between Los Angeles and the Grand Canyon eventually evolved into a "six-day" endurance test between Los Angeles and New York by the U.S. Auto ...
The test results are specified in seconds (s), more often than not referencing the test: Saybolt universal seconds (SUS); seconds, Saybolt universal (SSU); seconds, Saybolt universal viscosity (SSUV); and Saybolt FUROL seconds (SFS); seconds, Saybolt FUROL (SSF). The precise temperature at which the test is performed is often specified as well.
Old World Industries (OWI) is an American automotive and chemical company best known for their PEAK brand of motor oil, antifreeze and other automotive products. The company markets itself as an "independent, family-owned business". It sells products in over 60 countries. [2] [3] [4] [5]
