SUPERSEDED (see Active link, below)
ASTM D7589
1. Scope
1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty trucks with gross vehicle weight 3856 kg or less. The tests are conducted using a specified spark-ignition engine with a displacement of 3.6 L (General Motors) on a dynamometer test stand. It applies to multi viscosity grade oils used in these applications.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exceptions Where there is no direct equivalent such as the units for screw threads, National Pipe threads/diameters, tubing size, and single source supply equipment specifications. Additionally, Brake Fuel Consumption (BSFC) is measured in kilograms per kilowatthour.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
