While you and I may understand that. When your boss is telling you to oil the chains in the sawmill and you tell him it’s time to change the oil in the trucks because your out of burn oil. Then he buys you a whole case of chain and sprocket lube and you tell him it works like **** and you need the used oil. He just looks at you sideways, like he doesn’t believe you. Or your treating the deck on a flatbed and the same thing, I don’t want crappy used oil on the deck and he gets cheap new motor oil and it just globs on the deck and won’t soak into the wood. Lol
