Description

1.1”This test method measures the ability of an engine crankcase oil to control valve-train wear in spark-ignition engines at low operating temperature conditions. This test method is designed to simulate extended engine cyclic vehicle operation. The Sequence IVB Test Method uses a Toyota 2NR-FE water cooled, 4 cycle, in-line cylinder, 1.5”’L engine. The primary result is bucket lifter wear. Secondary results include cam lobe nose wear and measurement of iron (Fe) wear metal concentration in the used engine oil. Other determinations such as fuel dilution of the crankcase oil, non-ferrous wear metal concentrations, total fuel consumption, and total oil consumption, can be useful in the assessment of the validity of the test results.2
