Do All Turbocharged Cars Burn Engine Oil?

[JosieAnn]

Not all turbocharged engines burn engine oil, but turbocharged engines operate at significantly higher temperatures, which leads to some oil consumption and makes them more prone to burning oil compared to naturally aspirated engines. More details are as follows: 1. The pressure and temperature during engine operation are greatly increased, resulting in a shorter lifespan compared to naturally aspirated engines of the same displacement. The increased pressure directly leads to higher temperatures, thinning the engine oil under high heat. Under high temperature and pressure, the oil is prone to vaporizing and entering the combustion chamber through the cylinder walls, where it is burned along with the fuel. 2. Turbocharged engines can increase the intake air volume without changing the displacement, thereby enhancing engine power. They also effectively control exhaust emissions, contributing significantly to global energy conservation and emission reduction. 3. Current engine manufacturing technology is highly advanced, and the issue of turbocharged engines burning oil has improved significantly compared to naturally aspirated engines. Even if a small amount of oil enters the combustion chamber, the quantity is minimal and not a major cause for concern.
