Sludge sticks to walls, collects dirt, and gradually narrows the channels that carry oil through your engine. Oil filters have a limited capacity, and once they become clogged, unfiltered fluid circulates through the system.
Oil Change Delayed Engine Life: Consequences of Skipping Changes
As contaminants accumulate, the fluid loses its capacity to absorb and dissipate heat. Overheating and Thermal Breakdown Oil does more than lubricate; it carries heat away from combustion chambers and moving components.
Reduced Fuel Efficiency Old oil is thicker and creates more resistance as the engine turns. This drag forces the engine to work harder, which increases fuel consumption.

Instead, they grind and scrape, generating heat, noise, and microscopic metal particles that further damage surfaces. How Oil Degrades Over Time Fresh oil is clean, viscous, and formulated to suspend contaminants.
