Am I a hoarder, an enthusiast, or just plain crazy (my family's assessment)? I will cruise the Clearance sections of WalMart, Target, hardware stores, auto stores, etc., and anywhere else that might sell oil. I will purchase anything cheap (within reason) that I think could remotely be used someday in a car that myself or a family member owns. As a result, I have a couple shelves full of random quarts in my garage, many of which I have only one quart of. And it constantly grows. What's the diagnosis of my condition?
