Wow, really? Not being sarcastic--I am truly surprised. When I poured Swepco into my transmission a couple months ago, that stuff was so thick, little strings of fluid (think melted cheese from a pizza) would trail off from the bottle mouth when I stopped pouring. That's gotta be way more viscous than regular motor oil, I thought.

As an aside, where do you guys dispose of used gear oil? The local auto parts stores won't take it (citing its blue color). The local lube shops (Jiffy Lube/EZ Lube) won't take it.
