When I say formulated I mean castor mixed with the appropriate additives package i.e. VI improvers, EP addatives, friction modifiers, anti-oxidants, dispersants etc. etc. etc. These are only present in PPM quantities but they make a huge difference in how the oil performs. Want to truly know how much your local fuel guy knows about what he is doing, ask him about those lol. Most will probably just sit there with a dumbfounded/confused look in their eyes
