ABSTRACT:
A blend of solvent-extracted neutral (SEN) oils is described which is particularly useful in formulating heavy duty motor oils for lubrication of both diesel and gasoline engines. SEN 100, 140, and 300 are combined in required proportions to meet specified viscosity and boiling range characteristics. This base oil blend, upon the addition of lubricant additives to form a finished motor oil, provides the basis of an SAE 10W-30 grade CD/SF oil that meets the specifications for lubrication of both turbocharged diesel and gasoline engines.
