Moral of the story for me would be to just stay away from Rotella until Shell properly markets and labels their oil.
Come on already, SHELL, sort of a respected name in the industry showing its colors as a an oversize, mismanaged, lumbering company that can not even get the proper materials out to the public in regard to what classifications they are claiming for their products.
Pick a different company, its really that simple and there are MANY products from other companies just as good and better at the same price and lower. Why trust a company that produces an image of the "tail wagging the dog" ?
