Question: Why can’t I use BG 44K® in diesels?
Answer: Many have used BG 44K® in diesels but it is specifically formulated for gasoline engines, which don’t reach the same temperatures as diesel engines.
Because diesel engines run hotter and at higher compressions, they must withstand stresses far beyond those in gasoline engines. BG 244 is customized for the high pressure and heat in diesel engines. It was designed with ultra low sulfur diesel in mind, which generally lacks the lubricity of the older, low sulfur fuels. BG 244 reduces exhaust, cleans the fuel system, restores fuel economy and performance and smoothes engine idle.
