Description

ASTM D6837-13

Redline Standard: Standard Test Method for Measurement of Effects of Automotive Engine Oils on Fuel Economy of Passenger Cars and Light-Duty Trucks in Sequence VIB Spark Ignition Engine

ASTM D6837

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 of 3856 kg or less. The tests are conducted on a dynamometer test stand using a specified spark-ignition engine with a displacement of 4.6-L. It applies to multiviscosity grade oils used in these applications.

1.2 This test method also provides for the running of an abbreviated length test that is referred to as the VIBSJ. The procedure for VIBSJ is identical to the Sequence VIB with the exception of the items specifically listed in Annex A13. The procedure modifications listed in Annex A13 refer to the corresponding section of the Sequence VIB test method.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3.1 Exceptions—Where there is no direct SI equivalent such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. Brake Specific Fuel Consumption is measured in kilograms per kilowatthour. In Figs. A2.4, A2.5, and A2.8, inch-pound units are to be regarded as standard.

1.4 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.

1.5 This test method is arranged as follows:

Keywords

aged test oil; brake specific fuel consumption; break-in; calibration oil; flying flush; fuel economy; reference oil; sequence VIB; spark-ignition automotive engine
