Heavy-duty diesel engine oil additives are packages that enhance a lubricant's ability to prevent excessive wear and deposits in engines that use low- and high-sulfur-content diesel fuels. Afton Chemical additives help protect heavy-duty diesel engines from soot-related problems such as viscosity increase and oil filter plugging. We are North America's leading supplier of additives for heavy-duty diesel engine oil applications.
