European Test Methods For Fuel Economy Oils

Europe is well aware of work by the ASTM Fuel Efficient Engine Oil Task Force to develop test procedures for the measurement of the effects of the engine oil on the fuel economy of passenger cars and light duty vehicles. These procedures are designed to cover North American requirements and are not entirely suitable for European needs. The paper explains why separate European test methods are required for evaluating fuel economy oils and gives a status report on work by the Coordinating European Council to develop Codes of Practice for chassis dynamometer and fired engine dynamometer testing of fuel economy oils.
