In the car world, yes the markings are from the factory. But once you know the car has had quite a few services under it's belt, and you see the markings (especially at the drain plug), the service was usually done at a cheepie quick lube. Like, Walmart, Pepboys, Jiffy Lube, etc... That is when its bad to see them. I cringe at those places.
