OK, once again, I do not believe that 5w-20 is the liquid anti-Christ, but I still have my reservations about just how thin we can go. Things like the warning pictured below on the back of a Havoline bottle do nothing to give me a warm fuzzy about the product, especially since none of the other Havoline grades have such a statement on their bottles. This one is similar to one I saw on another bottle a couple months ago at a tire store (couldn't get there to track that one down, but I did find this at a nearby Autozone). I did NOT see a similar statement on the other brands present. Now, I know that posting this is probably going to be like tossing a Molotov coctail into the discussion group, but what do you all think it means? Why only on 5w-20???
