Description

Significance and Use

Test Method — The data obtained from the use of this test method provide a comparative index of the fuel-saving capabilities of automotive engine oils under repeatable laboratory conditions. A BL has been established for this test to provide a standard against which all other oils can be compared. The BL oil is an SAE 20W-30 grade fully formulated lubricant. The test procedure was not designed to give a precise estimate of the difference between two test oils without adequate replication. The test method was developed to compare the test oil to the BL oil. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485 .

Use — The Sequence VID test method is useful for engine oil fuel economy specification acceptance. It is used in specifications and classifications of engine lubricating oils, such as the following:

Specification D4485 .

API 1509.

SAE Classification J304.

SAE Classification J1423.

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.

1.4 This test method is arranged as follows:
