Abstract
Since emission control devices are mandatory on the 1968 automobiles nationwide, the recirculation of blow-by gases within the engine necessitates a new approach to the evaluation of engine oils. New test methods incorporating these closed ventilation systems, namely, the Falcon Rust Test and the Sequence V-B Sludge Test, are necessary for predicting motor oil performance.
Closed ventilation systems increase the load on the motor oil, and complicate the lubrication mechanism because these highly acidic blow-by gases are recycled. In the West Coast area, where both open and closed systems were first used, performance of many branded motor oils deteriorated; others were unaffected. Examples of corrosive engine wear were observed where improper motor oils were used.
It is the intent of this paper to provide a portion of the technical record of meeting this challenge, and to point out important oil test parameters and additive combinations effective in meeting these new problems.
