Abstract
The paper reviews the re-refining of used automotive engine lubricating oils to obtain lube stock with the right
characteristics and additives’ response suitable for blending automotive engine lubricating oil. The caustic treatment and
subsequent vacuum distillation method for re-refining of used automotive gasoline engine lubricating oils was used in this
investigation. A lube stock with the appropriate properties and characteristics including additive response for the
formulation of SAE 40 grade lubricating oil suitable for an automotive gasoline engine was obtained from a blend of rerefined used lubricating oil and virgin bright lube stock in the ratio 3:1. The lube stock had a viscosity index (VI) of 105.
