3 Main Reasons for Oil Consumption: Expert Explains Why Oil is Being Consumed

Increased motor oil consumption is most often related to engine wear, as racing driver SMP Racing Konstantin Sugrobov explained. According to him, the first and most common reason is wear and tear on the piston rings and cylinders. Compromising the sealing of the combustion chambers due to wear and tear is a significant cause of oil consumption in engines. Another key factor contributing to oil consumption is the deterioration of valve stem seals, which can allow oil to leak into the combustion chamber during engine operation. This leakage results in oil burning along with fuel, leading to increased consumption.
