API CK-4 and FA-4 oils will have to pass the seven existing CJ-4 tests for licensing qualification. In addition, there will be two new tests added measuring improved oxidation and aeration.
Since there are no specific fuel economy tests currently, these two new tests will indicate the oil's ability to provide fuel economy benefits and enhanced engine protection.
