API has learned that high demand for the ASTM D7528 (ROBO) test resulting from testing in advance of the May 1, 2020 first-licensing date for the new ILSAC GF-6A, ILSAC-GF-6B and API SP with Resource Conserving standards, has contributed to a backlog at independent test laboratories. With this in mind, API’s Engine Oil Licensing and Certification System (EOLCS) has invoked Provisional Licensing in accordance with paragraph 6.7 of API 1509 for what is commonly referred to as the ROBO test.
ASTM D7528 is the standard test method for bench oxidation of engine oils by ROBO Apparatus, which is one of several bench tests for motor oils licensed for use in passenger cars. The test measures an oil’s ability to maintain low temperature viscosity after aging.
API will grant a provisional license or licenses to an applicant if the candidate engine oil meets all API licensing requirements except for the ROBO test. In addition to ILSAC GF-6A, ILSAC-GF-6B, API SP with resource conserving and API SP with SN PLUS, provisional licensing for ROBO testing will also apply to ILSAC GF-5; API SN with resource conserving and SN PLUS; API SN with resource conserving; API SN with SN PLUS; and API SN.
Provisional Licensing will begin immediately and will close on August 1, 2020. On August 1, API will review the situation at the independent labs and determine if the provisional licensing period should be extended.
