Standard Test Method for Evaluation of Automotive Engine Oils in the Sequence IVB Spark-Ignition Engine

Importancia y uso:

5.1 This test method was developed to evaluate automotive lubricant’s effect on controlling valve-train wear and overall engine wear for overhead camshaft engines with direct acting bucket lifters.

5.2 Average intake lifter volume loss is used as a measure of an oil’s ability to prevent valve-train wear.

5.3 End-of-test oil iron concentration is used as a measure of an oil’s ability to prevent overall engine wear.

Note 2: This test method may be used for engine oil specifications such as API SP, and ILSAC GF- 6A, and GF-6B.
