For example, SM or CF. The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible. API Gravity Definitions: Definition of API Gravity of water provided by WikiPedia: The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water. if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.

The evolution of engine design has pushed the motor oil grading system for better motor oil service ratings. API Engine Oil Service Category Chart "S" Status: (ACC) Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Testing Guidelines. They may be used where API Service Category SH API Gravity is the oil industry standard used to determine and classify the density of oil. Density is an integral part of determining the value of oil, where light oils command a higher price due to the ease with which they are converted to gasoline. Get the API Weekly Crude Oil Stock results in real time as they're announced and see the immediate global market impact.

API SN Engine Oil Category. 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

Oil. Originally there was crude oil. Black gold. Texas Tea. As crude oil, it is fairly much useless. When you consider an oil grade for dino oils, think of it as an average. Here is a general chart of which oil should be used in which temperature  API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval. The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations. On November 9, 2017, the API Lubricants Standards Group approved the adoption of SN PLUS, a new classification that may be used in conjunction with API SN and API SN with Resource Conserving. API began licensing oils against the SN PLUS classification on May 1, 2018. API Introduces Three New Gasoline Engine Oil Standards, ILSAC GF-6A, GF-6B, and API SP. API’s Lubricants Standards Group approved by letter ballot the adoption of two new ILSAC specifications, GF-6A and GF-6B, and a new API Service Category, API SP. Motor Oil Guide. This four-page laminated guide is designed to help consumers understand the API Engine Oil Quality Marks—the API Certification Mark "Starburst" and Service Symbol "Donut"—and the API Service Categories.

The evolution of engine design has pushed the motor oil grading system for better motor oil service ratings. API Engine Oil Service Category Chart "S" Status: (ACC) Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Testing Guidelines.

API API Engine Oil Service Category Charts Licensed from May 1, 2018, API SN Plus is a new API classification that can be used alongside API SN, API SN  ENGINES charts on the next pages for descriptions of current and obsolete API service categories. 2. VISCOSITY GRADE. The measure of an oil's ability to flow  

Liquid petroleum pumped from oil wells varies by quality, economic value, and potential toxicity. Learn about the classifications of crude oil.

4 Jun 2015 Viscosity increases with decreases in crude oil API gravity (assuming a constant Watson characterization factor) and decreases in temperature. We now have two motor oil product lines which are API Certified and Dexos 1 as engine oils with the API certification donut provided these other viscosities  1 Jan 2016 Grease Compatibility Chart dexos1™, ILSAC GF-5 or API SN performance lubricants. require SAE 10W-40 viscosity grade oils up to and. unobtainable in oils of such low viscosities, are the result of advances For petrol engines lubricant specifications have advanced from API SA through to the   Vehicle owners should refer to their owner's manuals before consulting these charts. Oils may have more than one performance level. For automotive gasoline   Engine Oil At-A-Glance Chart the Automotive Performance Institute (API) specifications for performance. Monolec GFS Engine Oil is a a straight-grade engine oil formulated for extended drain service, primarily in off-road diesel engines.

MOT OR OIL. Follow your vehicle manufacturer’s oil change recommendations. This includes using recommended SAE oil viscosity and ILSAC or API performance standard. If you find it necessary to mix brands of oil, use same viscosity grade and API service category to maintain performance. Properly dispose of used oil. Learn more about recycling GUIDE TO SAE VISCOSITY GRADES OF MOTOR OIL FOR PASSENGER CARS. Multigrade oils such as SAE 5W-30 and 10W-30 are widely used because, under all but extremely hot or cold conditions, they are thin. enough to flow at low temperatures and thick enough to perform satisfactorily at high temperatures. API SN Engine Oil Category. 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.
