Furthermore, the high-pressure fuel system and variable geometry turbo create soot and acids that the additive package must neutralize effectively to keep the internals clean and functional. The engine utilizes a Diesel Particulate Filter (DPF) to meet emissions standards, which requires the oil to have a very low Sulfated Ash content (SAPS) to prevent clogging the filter.
CJ-4 oils are designed to handle the higher combustion temperatures and sulfur content levels found in today's ultra-low sulfur diesel fuel. This specification, developed by the American Petroleum Institute, supersedes previous generations and ensures the oil meets the rigorous demands of modern diesel technology.
