Engine oil or motor oil refers to lubricating fluids formulated specifically for use in internal combustion engines rather than external moving parts. It has properties tailored to the intense demands inside engines.
This petroleum-based fluid is composed of base oils that are refined from crude oil and blended with a variety of performance additives. The nature and quality of the base stock and additive packages differ between brand, viscosity grade, and specifications.
The viscosity grade of an engine oil indicates oil flow properties at high and low temperatures. The SAE viscosity rating contains numbers and sometimes a “W” to indicate “Winter” or low-temperature performance.
The grade can either be monograde, for example, SAE 10W or SAE 40. Or they can be multi-grade like SAE 10W-30 and 15W-40. Lower numbers have lower viscosity for easy flow, while higher viscosities provide film strength and ensure durability even at higher temperatures.
Several industry specifications may be referred to on the engine oil name, container or product data sheets, such as API, ACEA or JASO.
The American Petroleum Institute (API) sets minimum performance standards for engine oils indicated by “S” for gasoline (service category), “C” for diesel engines (commercial category) and “F” for lower viscosity oils for heavy-duty diesel engines.
The latest specifications currently in these categories are API SP for gasoline, API CK-4 and API FA-4 for diesel engines.
ACEA (European Automobile Manufacturers' Association) also sets performance standards for engine oils, offering the “A/B” Sequence for Gasoline & Light-Duty Diesel Engines, “C” Sequence for Gasoline & Light-Duty Diesel Engines with exhaust after-treatment devices, and the “E” Sequence for heavy-duty diesel engines.
Japanese Automobile Standards Organization (JASO) provides specifications for motorcycle oils and scooter oils, such as JASO MA, JASO MA2 and JASO MB, which ensures that the oil is suitable for use in these applications.
Besides these, several OEMs like Mercedes-Benz, Ford, Volvo etc. also have specifications, which are usually recommended in their vehicles, and ensure that the oil is superior to the standards set by the Industry Associations.

It is a long established fact that a reader will be distracted by the readable content of a page
when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal
distribution of letters, as opposed to using 'Content here, content here', making it look like
readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their
default model text, and a search for 'lorem ipsum' will uncover many web sites still in their
infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose
(injected humour and the like).
