Are Turbocharged Engines More Prone to Burning Oil?

Turbocharged engines are more prone to burning oil compared to naturally aspirated engines. Here are the relevant details: Reasons why turbocharged engines are more prone to burning oil: Many engines use aluminum alloy cylinder blocks and other components. Since all metals expand with heat and contract with cold, during turbo operation, the gap between the engine cylinder and piston will shrink due to the rapid rise in temperature. Therefore, turbocharged engines are designed with a wider initial gap between the cylinder and piston compared to naturally aspirated engines to prevent component damage from thermal expansion. As a result, when the engine starts, under the same oil viscosity conditions, turbocharged engines allow more oil vapor to enter the combustion chamber than naturally aspirated engines, leading to oil burning.
