IMPROVED FUEL ECONOMY VIA ENGINE OILS

A fuel-efficient passenger car engine oil has been developed that showed average of 4.6% improvement in fuel economy compared with several premium, SAE 10W-40 oils (API Engine Service Classification SE) in a road fleet test. In the comined Environmental Protection Agency city/highway testing, this oil gave 5.5% better fuel economy on average than an SE premium 10W-40 oil. The excellent over-all performance of this lubricant was confirmed by ASTM Engine Sequence tests and evaluation in severe taxicab operations.
