Outstanding overall engine performance has been obtained by formulating automotive engine lubricants with synthetic base stocks. This paper summarizes the performance features of an optimized SAE 10W-30 synthetic passenger car engine oil. Comparisons to premium mineral oil-based products are made in areas of fuel economy, low-temperature cranking, high-temperature deposition, antiwear performance, quality reserve capability, and oil consumption control. Supporting data are shown from tests involving U.S., European, and Japanese vehicles.. ABSTRACT. FORMULATIONS AND PHYSICAL PROPERTIES. COD CRANKING PERFORMANCE. FUEL ECONOMY FPERFORMANCE.
