Your car’s engine runs on oil, much like we run on water. Oil lubricates the moving parts, reduces friction, and helps control the engine’s temperature. But over time, oil breaks down and collects dirt, dust, and debris. If it’s not replaced regularly, it becomes less effective, leading to decreased performance, increased fuel consumption, and eventually, costly repairs. https://inoutcarwash.com/why-is-an-oil-change-the-most-important-service-at-in-n-out-car-wash/
