API CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm. However, the use of these oils with greater than 15 ppm sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval.
- API CK-4 oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase.
- API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.

His thread title states it's a 1025R. As for oil, as long as it meets JD specs, any brand of oil would be OK to use. Personally, I'm one to stick with JD products, no matter what I need at the time. I switched my 2009 2520 from conventional oil, to JD full synthetic in 2011.

For engine oil for diesels manufacturers are always tweaking the chemistry of them in order to meet emissions standards and other requirements. I have gone through 2 or 3 versions since I have had my diesel truck and have suffered no ill effects. The newer versions should meet or exceed the requirements of when your engine was produced.
Like many others on here, I stick to the JD brand stuff but I am sure I am just over paying for it. My engine doesn't take a whole lot so it's no big deal to me to have peace of mind.
