Dirty engine oil can cause serious damage because it loses its ability to properly lubricate and protect moving parts. As oil ages, it collects dirt, metal particles, and combustion byproducts that turn it abrasive rather than protective. Instead of reducing friction, dirty oil increases wear on components like pistons, bearings, and camshafts, leading to 1€ overheating and reduced engine efficiency. Sludge buildup can also block oil passages, starving critical parts of lubrication and accelerating long-term damage. Regular oil changes keep the oil clean and effective, helping the engine run smoothly and preventing costly mechanical failures over time.
