API ANNOUNCES IMPROVED ENGINE OIL STANDARDS
First Licensing for GF-6A, GF-6B and API SP set for May 1, 2020
WASHINGTON, June 5, 2019 – Today, API announced the approval of improved performance standards for engine oils that will provide greater protection and fuel efficiency for today’s gasoline-engine-powered cars and trucks.
Two of the new standards, ILSAC GF-6A and GF-6B, are the latest in a line of more stringent performance specifications put forward by the International Lubricant Standardization Advisory Committee (ILSAC), and a third standard, AP SP, is API’s latest engine oil performance standard. API SP includes all of the ILSAC requirements while at the same time provides performance requirements for oils that do not fall under ILSAC-member recommendations. The new standards specify more stringent engine oil performance requirements for spark-ignited internal combustion engines. All three of these standards can be licensed under API’s Engine Oil Licensing and Certification System beginning May 1, 2020.
“API developed these new performance standards in response to a request from automakers to introduce more robust engine oils that would be capable of meeting the needs of current and future gasoline engines. ILSAC GF-6A, GF-6B and API SP represent the fruits of the oil, additive, and automobile industries’ labors to introduce such essential products for the people who use these vehicles every day,” said Kevin Ferrick, director, API Product Programs.
The development of ILSAC GF-6A, GF-6B and API SP was done over the course of seven years. In that time, seven new tests were developed, evaluated, and measured for precision, and companies ran tests to demonstrate that oils can meet the more stringent requirements. Now, oil marketing companies are working to bring the oils that meet these standards to market to ensure current and future engines perform as designed.
Licensed oils that meet the ILSAC GF-6A standard will be allowed to display the API Certification Mark “Starburst” and may be used where oils meeting GF-5 or earlier gasoline engine oil standards had been recommended. Oils that meet ILSAC GF-6B will be allowed to display a new mark, the API Certification Mark “Shield,” and may be used where SAE 0W-16 oils meeting API SN had been recommended. API is introducing this new “Shield” at the request of automakers to prevent confusion and ensure that 0W-16 oils are used only in applications where they are recommended.
API standards are developed under API’s American National Standards Institute accredited process, ensuring that the API standards are recognized not only for their technical rigor but also their third-party accreditation which facilitates acceptance by state, federal, and increasingly international regulators. API’s GIS division is responsible for standards setting, certification, training, events, publications and safety programs for industry operations.
API is the only national trade association representing all facets of the natural gas and oil industry, which supports 10.3 million U.S. jobs and nearly 8 percent of the U.S. economy. API’s more than 600 members include large integrated companies, as well as pipeline, exploration and production, refining, marketing, marine businesses, and service and supply firms. They provide most of the nation’s energy and are backed by a growing grassroots movement of more than 47 million Americans. API was formed in 1919 as a standards-setting organization. In its first 100 years, API has developed more than 700 standards to enhance operational and environmental safety, efficiency and sustainabilit

ASTM D7320
試驗方法是為了評估汽車發動機油在中度高速、高溫使用時，對機油的增稠及引擎磨損的保護。
在该试验中得到的机油粘度的增加表明机油因氧化而变稠的趋势。在汽车维修中，这种增稠会导致机油泵饥饿，从而导致发动机的灾难性故障。
机油的沉淀物等级表示机油在整个发动机中形成沉淀物的倾向，包括那些可能导致活塞环在其凹槽中粘连的沉淀物。这可能涉及到发动机的压缩压力损失。
在本试验中获得的凸轮轴和升降机的磨损值，是衡量机油在高单位压力机械接触条件下的抗磨质量的指标。

大家騎機車如果要符合規範 要使用JASO T903規範喔!! 不然可能會超標喔 本文最後由 pompom 於 2020-4-28 19:03 編輯
