What is API SA oil?

What is API SA oil?

As shown above, API “SA” oil was the first in the API Service Classification for gasoline motor oils. These oils were formulated for use in vehicles built prior to 1930. That’s right, motor oil made for cars built nearly 80 years ago!

What are API service classifications?

The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. It specifies the viscosity grade required for your car’s engine.

What is Type SA oil used for?

According to Industry data 10 to 15% of ALL motor oil sold in USA is API SA rated or plain pure petroleum motor oil, majority of which is of SAE 30 viscosity. The SAE 30 is too thick for typical machine oil or industrial oil use, and historically almost all of it is used as motor oil in engines.

What does API Service Sp mean?

SP is the API’s newest service category. ILSAC GF-6 applies to the fuel efficient viscosity grades, while API SP applies to those heavier viscosity grades like 10W40 and 20W50. API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.

What does SF mean in motor oil?

Now the letters. An API service rating of “SF” means the oil meets all new car warranty requirements for 1981 and newer models. “SE” means the oil is usable in all 1972-1980 vehicles. “SD” means the oil is good for all 1968-1971 cars. “SC” is adequate for all 1964-1967 models.

What is the difference between CJ 4 and CK 4?

API CK-4 oils will replace current API CJ-4 engine oils and will be backward compatible with most applications where engine manufacturers currently recommend CJ-4. The new CK-4 oils will provide a number of improvements over CJ-4, including improved shear stability, oxidation resistance, and aeration control.

What is the difference between CJ-4 and CK-4?

What is the difference between API SN and SM?

In 2010 the American Petroleum Institute introduced a new engine oil category under the name API SN and a new supplemental category called Resource Conserving. The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons. Better sludge control.

What is SF 15w40?

MOTOR OIL SF 15W-40 is a multi functional mineral engine oil for older gasoline-, diesel- and LGP engines of passenger car and light vans with or without turbo compressor. MOTOR OIL SF 15W-40 is not suited for engines equipped with a Diesel Particle Filter (DPF).

What is the difference between API SN and SP?

GF-6B oils replace 0W-16 oils. API SP replaces all API SN. This includes a timing chain wear test and fuel economy improvement test when using very low viscosity oils, among other tests.

Is API SP higher than SJ?

As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars.
