What is API motor oil?
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.
What is API standard for oil?
American Petroleum Institute (API) standards advocate proven, sound engineering and operating practices and safe, interchangeable equipment and materials from drill bits to environmental protection. Included are manuals, standards, specifications, recommended practices, bulletins, guidelines and technical reports.
Is API sp better than SN?
Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. If an automotive owner’s manual calls for an API SN oil, an API SP oil will provide full protection.
What is the difference between API SN and API 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.
What is 15w40 oil used for?
ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.
What is API premium oil?
Premium multi–Grade Gasoline Engine Oil is formulated with highly refined base stocks and selected DI Packages which provides excellent wear control.
What is API SF oil?
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.
What does API SP stand for?
Modern engines are packed with technologies built to improve efficiency and power. API SP is the latest engine oil standard issued by the American Petroleum Institute, a trade association that represents all segments of the natural gas and oil industry.
Can you mix SN and SP oil?
API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.
Is SN better than SM?
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. Better seal compatibility.
Can I use 10W40 instead of 15w40?
A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. 10W40 oil will perform cold starts better than 15W40 oil.
