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 .
It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC, TD). Being a very old standard itself, most currently produced 2T lubricants meet its specifications, even the lowest quality ones; current high-quality oils exceed them (often labeled "API TC+" although not based on actual measurements).
The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...
The SAE has a separate viscosity rating system for gear, axle, and manual transmission oils, SAE J306, which should not be confused with engine oil viscosity. The higher numbers of a gear oil (e.g., 75W-140) does not mean that it has higher viscosity than an engine oil 20W-50.
Shell Rotella is a line of heavy-duty engine lubrication products produced by Shell plc.The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating.
When oils get cold enough in a deep freezer, they will solidify into a block of "wax"-like oil that cannot be pumped around inside an engine's lubrication system. However, when a spoonful of very cold oil is put into a pan on a stove and it is slowly heated and swirled around, the oil will gradually warm up, and there is a definite temperature ...
