The Sequence IID Engine Oil Test 780931

The ASTM Sequence IIC test was established to evaluate the rust and corrosion protection provided by gasoline engine oils. It is one of the several tests currently used to define SE-quality engine oils. The test utilizes a 1967, 7.0 L Oldsmobile engine which is no longer available.
This paper describes the program to replace this engine with a 1978, 5.7 L Oldsmobile engine. The new test called Sequence IID also evaluates engine oil rust and corrosion protection, and it correlates with both Sequence IIC engine test and passenger car short-trip test results.
