AMSOIL Diesel Fuel Additives Best Choice for Increased Fuel Lubricity
AMSOIL Diesel Fuel Additives Best Choice for Increased Fuel Lubricity
Adequate diesel fuel lubricity is essential for protecting the highly engineered components in modern diesel engines, particularly high-pressure common-rail (HPCR) engines, which are subject to increased wear and deposits that interfere with an optimum spray pattern, reducing power and fuel economy. Many diesel owners add two-stroke oil to their fuel for added lubricity. AMSOIL delivers a better solution that provides additional benefits.

ULSD Provides Less Lubricity
Diesel fuel has traditionally had high lubrication properties, but the desulfurization process that allows fuel to meet modern ultra-low-sulfur diesel (ULSD) requirements also strips it of organic compounds responsible for lubrication. Although the ASTM D975 standard for diesel fuel provides a minimum level of lubricity, it’s not as much as the Engine Manufacturers Association (EMA) has called for.

Due to government mandates for reduced emissions, nearly all diesel fuel sold in North America is ULSD, which contains a maximum of just 15 ppm sulfur, compared to traditional diesel fuel that contained up to 5,000 ppm prior to EPA regulations taking effect in 2006. ULSD is also compatible with modern exhaust treatment devices, such as diesel particulate filters (DPF), that also help reduce emissions.
