Preliminary observations are offered about relationships between lubricant composition and formation of deposits in crankcase ventilation systems. Ashless dispersants, metallo-organic soaps, and base oils contribute to deposit control. A fully formulated oil was found to be slightly superior to an ashless dispersant-zinc type with respect to PCV plugging. The proposed Sequence 5B procedure distinguished the high performance oils from the lower quality ones.
