Webinar: What the new diesel oil specifications mean for agriculture

Last year’s long-awaited launch of two new API oil categories, CK-4 and FA-4, generated a lot of buzz in the on-highway trucking industry. But what is the significance of these new oils for off-highway vehicles, specifically tractors and farm equipment?


We recently conducted an online webinar with Farm Journal Media to answer that question. The bottom line: ag equipment operators that have historically used CJ-4 oils should seriously consider upgrading to the CK-4 category. These new oils are ideally suited to off-highway engines that operate under high-stress, high-temperature conditions. Moreover, they are backwards compatible, meaning they can be used in older equipment that has been using CJ-4 oils.


In the long run, CK-4 oils have the potential to help reduce your maintenance costs and optimize equipment life, generating a better return on your investment. Take a few minutes now and see how CK-4 oils benefit agricultural equipment.
