What problem can improper piston ring conditioning lead to?

• A. Low oil pressure
• B. High oil consumption
• C. Increased horsepower
• D. Reduced compression

Answer: (B)

Ring conditioning determines how well the piston rings seal and how effectively the oil control ring manages excess lubricant. When conditioning is done improperly, the rings may not seat correctly or form a tight seal, and the oil control mechanism can fail to remove oil from the cylinder walls. This allows oil to slip into the combustion chamber and burn with the fuel, leading to higher oil consumption (often accompanied by blue smoke). While poor ring sealing can also reduce compression, the most direct and common result of improper conditioning is increased oil consumption.
