Does having a large stockpile of oil at your house make any sense? I do not mean 5 or ten quarts of oil but gallons and gallons of the stuff. Are you the guy with 40 quarts of tri-syn in the garage. Or a bunch of dino SJ oil you bought before SL oils came out. The reason I ask is a lot of people on this board demand the best oil for their vehicles. And old oil MAY not be the best. Example #1: You are sitting on a small fortune of german castrol. Then somebody finds out that XZY auto parts store/oil company in importing some other fancy synthetic oil. Now you are stuck, new fancy synthic oil is better but you have hundreds of dollars in GC. For most people they would contiunue to use the GC, but I know some members of this board would have to run out and at least try something new if they thought it would be better. Example #2. You have a large number of 5 quart Mobil 1 jugs in your garage because they were 18.88 at walmart. Well 12 months from now GF4 is out and mobil has changed there formulation twice in that time (I understand they like to do that alot). What are you to do??? The point of all this is the oil seems to get better all the time, is easy to find/buy, does having more than a case on hand make any sense??
