    Q: What advantages do the new oil specifications hold for end users?

    A: These new specifications include new performance requirements that make API CK-4 and API FA-4 significant upgrades to API CJ-4. Most notably, oils that meet the new standards will have SIGNIFICANTLY improved oxidative stability. This means that they will be formulated to provide protection against premature breakdown, even when the oil is exposed to the very high operating temperatures that are common in today’s hard working engines. In fact, one of the new oil performance tests required by the new specs runs the oil at 130 degrees C (266 degrees F) for 360 hours in an engine running at full power! You can be assured that oils meeting the new standards are up to the task of protecting your engine, even under the harshest of conditions.
