Summary:

Piston ring land deposit formation is a key performance criterion in the ASTM Sequence IIIE engine test. Because engine testing of lubricant formulation variables is expensive, a ring land deposit bench test was developed replicating the Sequence IIIE bulk oxidation and deposit formation mechanisms. Following an initial bulk oxidation of the candidate oils, deposits similar in chemical composition and morphology to Sequence IIIE ring land deposits are produced in a modified panel coker apparatus. Good correlation with the ASTM Sequence IIIE engine test has been established. Lubricant additive and base oil effects on oxidation control and deposit formation have been investigated. Their influences on lubricant formulation strategy are discussed
