As oil circulates, it collects microscopic metal shavings, dust, and chemical byproducts of combustion. Old oil loses its thermal stability, meaning it breaks down when exposed to high temperatures.
Cylinder Walls Damage as Oil Delay Turns Sludgy
Engine oil is the lifeblood of your engine, performing a multitude of critical functions that keep your vehicle running smoothly. This increased viscosity forces the oil pump to work harder, reducing overall efficiency and leading to a drop in fuel economy.
Unlike other fluids in your car, engine oil is not replenished; it is consumed and contaminated over time. This heat not only accelerates the wear on engine parts but also causes further oxidation, creating a vicious cycle where the oil degrades even faster.
