Container Identification
The Engine Oil Certification Mark was developed and trademarked by the API to refer customers to those engine oils preferred by the automobile manufacturers. This symbol means that the oil has been certified and licensed by the American Petroleum Institute (API). This certification mark will only be found on the front of the oil containers. Those oils that do not display the "Mark" on the front of the container should not be used.
Chrysler only recommends API Certified engine oils that meet the requirements of Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395.
