The International Lubricant Standardization and Approval Committee (ILSAC) also has standards for motor oil. Introduced in 2004, GF-4 [28] applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils. In general, ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel ...
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.
Also, to free up power, some engines in performance applications run lower weight oil, which requires less power to run the oil pump. Common oil weights in engines today are usually either 5W-30 or 10W-30 oil, whereas performance engines might use 0W-20 oil, which is less viscous. [8]
A common hitch is 20 days on, followed by 10 days off. Typically, two crews will be on and each crew will spend one week working 7am-7pm and the following week 7pm-7am. Or, crews may do a full two weeks of 7am-7pm and then, upon returning after their 10 days off, will work the next two weeks 7pm-7am (the third rig crew being on their 10 days off).
Motor oil, a common lubricant.. 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.
The first number associated with the W (again 'W' is for Winter, not Weight) is not rated at any single temperature. The "10W" means that this oil can be pumped by your engine as well as a single-grade SAE 10 oil can be pumped. "5W" can be pumped at a lower temperature than "10W". "0W" can be pumped at a lower temperature than "5W"
Driving in Johannesburg, I once saw a billboard for a Cape Town real estate company inviting South Africans to “semigrate.” The word was a play on “emigrate,” what many white South Africans have been threatening to do—to a whiter country—since the end of white rule in 1994.
