Automotive Developments and Their Fuel and Lubricant Requirements

This paper describes some of the more recent fuel and lubricant requirements from the standpoint of the manufacturer. Four topics are covered: oil viscosity and cranking speeds, oil composition and heavy-duty truck engine preignition, octane requirements of 1963 Chevrolet engines, and chassis lubrication developments. Heavy-duty and paspenger car engines, air-cooled and water-cooled engines are directly related to these topics.
