(Test Method)Standard Test Method for Evaluation of Engine Oils for Roller Follower Wear in Light-Duty Diesel Engine
Standard Test Method for Evaluation of Engine Oils for Roller Follower Wear in Light-Duty Diesel Engine
SIGNIFICANCE AND USE
This test method is used to determine the ability of an engine crankcase oil to control wear that can develop in the field under low to moderate engine speeds and heavy engine loads. Side-by-side comparisons of two or more oils in delivery van fleets were used to demonstrate the field performance of various oils. The specific operating conditions of this test method were developed to provide correlation with the field performance of these oils.
This test method, along with other test methods, defines the minimum performance level of the Category API CG-4 for heavy duty diesel engine lubricants. Passing limits for this category are included in Specification D 4485.
The design of the engine used in this test method is not representative of all modern diesel engines. This factor, along with the specific operating conditions used to accelerate wear, shall be considered when extrapolating test results.
SCOPE
1.1 This engine lubricant test method is commonly referred to as the Roller Follower Wear Test. Its primary result, roller follower shaft wear in the hydraulic valve lifter assembly, has been correlated with vehicles used in stop-and-go delivery service prior to 1993. It is one of the test methods required to evaluate lubricants intended to satisfy the API CG-4 performance category. This test has also been referred to as the 6.2 L Test.
1.2 The values of units used in this test method are stated in either inch-pound units or SI units and are to be regarded separately as the standard.
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.

use of the test method gives results statistically similar to those obtained by other laboratories.
Furthermore, various agencies require that a laboratory utilize the TMC services in seeking
qualification of oils against specifications. For example, the U.S.Army imposes such a requirement,
in connection with several military lubricant specifications.
Accordingly, this test method is written for use by laboratories which utilize the TMC services.
Laboratories that choose not to use these services may simply ignore those portions of the test
procedure which refer to the TMC.
