I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
The "CD" oil grade, a classification by the American Petroleum Institute (API), specifies oils formulated primarily for use in heavy-duty diesel engines. This rating, established decades ago, has been superseded by newer, more stringent standards due to advances in engine design and emissions requirements. Modern equivalents to CD grade would fall under API's current classifications like CK-4 or CJ-4, designed for high-speed, four-stroke cycle diesel engines. These latest oil grades offer improved oxidation resistance, better shear stability, and enhanced aeration control. While CD oils are outdated, CK-4 and CJ-4 provide broader compatibility with modern engines, meeting or exceeding the performance requirements previously covered under the CD specification. Always consult your engine manufacturer's recommendation for the most suitable oil grade.
