What is API Standard?
What is API Standard?
Article by: Professor Polo
Date: October 2020
The American Petroleum Institute (API) developed a common standard, which is often reflected on oil packaging labels. This standard distinguishes the important index for each level of zinc and phosphorus content, the lower the content, the higher the API level. This standard limit the content of zinc and phosphorus in order to reduce the heavy metal content in automobile exhaust and pollution. Too much phosphorus in engine oil can easily make the three-way catalytic converter fail.
The current and previous API Service Categories are summarized in the chart. Vehicle owners should refer to their owner's manuals before consulting these charts. 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 SP oil, an API SP oil will provide full protection. For diesel engines, the latest category usually - but not always - includes the performance properties of an earlier category.
API FA-4 and the FA-4 Donut identify certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use.
POLO ProMax and POLO SYNMax gasoline engine oils meet the latest API and ULSAC GF6a specifications for gasoline engine vehicles. POLO TRAX diesel engine oil ranges of products meets the latest API specifications for diesel engine vehicles.
