How Ag equipment can benefit from the new oil categories

If you maintain tractors or other agricultural equipment, you’re no doubt aware of the recent introduction of two new API oil categories, CK-4 and FA-4, but you may not be sure what it means to you. True, the main driver behind the development of these oils was the redesign of diesel engines for greater fuel economy and lower emissions, but the ag industry stands to gain a number of benefits from these new oils- particularly from the CK-4 category.

Robust Testing to Match Quality Performance

Before we launched our Delo® 400 line of CK-4 and FA-4 products, we undertook the most extensive field testing ever for a Chevron Delo product launch. We tested our products across a wide variety of vehicle types, both on- and off-highway, including agricultural equipment. What we found in general, was that this new generation of oils performed better than comparable CJ-4 oils on a number of key measures – notably oxidation stability, piston deposit control and wear protection. These attributes are particularly valuable for farm equipment that operates in rugged, dusty conditions and high seasonal temperatures.  The improved characteristics mean that the oils can safely deliver longer drain intervals – equating to lower maintenance costs, less equipment downtime, and ultimately prolonged engine life.

As the agriculture industry progressively migrates to newer engine models, it’s also worth noting that all the major diesel engine manufacturers are now recommending longer drain intervals for these new oils when used with newer engines.

Transitioning to New Oils

Recognizing that the transition to the new oil categories is not as urgent an issue for ag and other off-road equipment operators, Chevron is keeping our Delo® 400 LE 15W-40 CJ-4 product available for an extended period to allow more time to make the switch. In the meantime, you might want to check out our Delo 400 Advanced Heavy Duty Engine Oils Transition Guide to help choose the right new oil based on what you currently use.
