Standard Test Method for Evaluation of Engine Oils for Roller Follower Wear in Light-Duty Diesel Engine

Importancia y uso:

5.1 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 torques. 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.

5.2 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 D4485.

5.3 The design of the engine used in this test method is not representative of all modern diesel engines. Consider this factor, along with the specific operating conditions used to accelerate wear, when extrapolating test results.
