Which outcome occurs when small amounts of liquid fuel bypass piston rings in an internal combustion engine?

💡 Explanation

Increased oil dilution and blow-by occurs because unburnt fuel contaminates the lubricant due to insufficient cylinder wall sealing via piston rings, degrading oil viscosity causing increased ‘blow-by’ pressure therefore, raising leakage as this oil is less effective at sealing, rather than compression loss itself.
