Evaluation of a Fuel Efficient Long Drain Ester Based Lubricant

A new SAE 5W-30 synthetic lubricant has been developed using a mixed ester base stock, a shear stable VI improver and a special DI additive package. Durability evaluation in a “combination tire test” and fuel economy studies in the SAE J-1082 procedure indicate extended drain capability and fuel economy benefits for the synthetic lubricant.
