HiTEC® 638 is an ashless dispersant for formulating crankcase oils. It has proven performance in controlling low-temperature deposits in natural gas engine oils, marine diesel oils, and other crankcase applications.
Engine oils are highly susceptible to carbon, sludge, and deposit buildup, resulting in dirty oil and frequent oil changes.
