Does the Focus Burn Engine Oil?

[EthanFitz]

Oil burning in the Focus is one of the phenomena that occur when the car engine malfunctions. The parts of the Focus engine that affect oil consumption include various sealing components, such as intake valve oil seals, exhaust valve oil seals, piston rings, the crankcase ventilation system, cylinder head gaskets, various sealing pads/rings, and oil seals. Factors influencing usage: The engine's RPM affects oil consumption differently. When driving at high RPMs, the engine operates at low torque/high speed, causing the pistons to move faster with less air-fuel mixture entering. This creates a higher vacuum in the intake system, increasing the tendency for the lubricating oil responsible for sealing the pistons, piston rings, and cylinder walls to enter the combustion chamber, thereby raising the possibility of oil consumption. The main reasons for a car burning oil are roughly the following: 1. Severe wear of the piston rings responsible for sealing; 2. Over time, incomplete combustion byproducts; 3. Severe wear of the cylinder or cylinder walls, leading to excessive clearance between them, allowing excessive oil to enter the combustion chamber;
