Standard Test Method for Evaluation of Performance of Automotive Engine Oils in the Mitigation of Low-Speed, Preignition in the Sequence IX Gasoline Turbocharged Direct-Injection, Spark-Ignition Engine

Importancia y uso:

5.1 This test method evaluates the ability of an automotive engine to mitigate preignition in the combustion chambers in turbocharged, direct injection, gasoline engines under low-speed and high-load operating conditions.

5.2 Varying quality reference oils, with known preignition tendencies, were used in developing the operating conditions of the test procedure.

5.3 The test method has applicability in gasoline-engine-oil specifications and is expected to be used in specifications and classifications of engine lubricating oils, such as the following:

5.3.1 Specification D4485.

5.3.2 ILSAC GF-6.

5.3.3 SAE Classification J183.
