Abstract
Introduction : Any suitable lubricating oil performance can be modified by controlling the amounts of different cuts and using additives so as to give lubricating oils a broad range of uses. Blending of different cuts of lubricating oil ranges of Brega crude had been investigated to obtain an optimum base oil before adding any additives.
Preference for wax-free crude oils in the production of lubricating oils is discussed. Solvent extraction and dewaxing enable the use of a wider range of crude oils. The type and concentration of additives in lubricating oils vary based on applications, types of operations, and the ranges of cuts used in the blending program.
