Which outcome is observed when cylinder wall lubrication fails, causing excessive wear on piston rings in a high-performance internal combustion engine?

💡 Explanation

Increased crankcase oil dilution occurs because excessive wear due to boundary lubrication regime breakdown degrades sealing; therefore, combustion gases and unburnt fuel blow-by past the piston rings contaminates the oil, rather than being efficiently combusted, leading to cleaner exhaust.
