Caterpillar Raises the Bar for Engine-Oil Performance

摘要

Caterpillar issued the ECF-1 engine-oil standard, which the engine maker says should be applied in addition to the American Petroleum Institute (API) CI-4 standards, to protect Cat engines from soot, wear and piston deposits. In the past, Cat has recommended owners of 3500 Series and smaller engines use diesel engine oils that meet the most current specifications of the API. CI-4 oils were introduced to protect truck engines with exhaust-gas recirculation (EGR), and Cat is now recommending additional performance tests to ensure the durability and reliability of all Caterpillar engines, none of which use EGR to meet emissions limits.
