I don't see any reason to have an oil stash, and I'm going to define a stash as oil that won't be used within a year.
How do you know that the oil you've stashed won't be obsolete before you can use it up? Given the great strides in the increase in the quality of oil, oil you buy now may not be as good for your vehicle as new formulations that may be only a couple years away.
What if you exchange your vehicle(s) for
vehicle(s) in which you should not use your stashed oil?
What if you change your oil philosophy and decide to switch from dino to syn (or visa versa). You have a stash of the kind of oil you're switching away from.
So what if your stashed oil was all bought on sale or with a rebate? Within any given period of from a week to a few months time you can always find oil on sale or with a rebate. If you plan a few months to a year ahead you can always change your oil with oil you bought on sale or with a rebate within the last year, and remember, I'm defining a stash as oil that won't be used within a year after you buy it.
Why tie up your money in something that won't earn income for you?
Why needlessly tie up your storage space? And who among us can't use more storage space, and doesn't wish we had more?
Have you ever seen an oil depot go up in flames? They'll never be able to put your garage fire out. They'll die laughing when you tell them the black smoke's from your 300 quart oil stash.
Aren't you tired of justifying your stash to your wife? She thinks you're nuts you know. Since I joined BITOG I extoll the benefits of this and that oil and oil filter for our vehicles and small engines, and other things BITOG-related and she could care less, except that she kept ragging on me about my "oil stash". That is, until last weekend when she came into the garage and I showed her my stash. Six quarts of Castrol GTX I'd bought the day before for the yearly oil changes in our two lawn movers, snowblower, and rototiller, a 2/3 full jug of Castrol GTX used as chainsaw bar and chain oil (so that doesn't even count). A jug of Mobil 1 EP with a half quart left in it from my last oil change in her Subaru Forester, a quart of Havoline from my pre-syn oil days when I ran dino Havoline and dino Valvoline, a quart bottle of Super Tech with about a cup of oil left in it, and a quart each of Mobil 1 and Mobil 1 EP. "So don't bug me about having an oil stash" I said. I guess I told her!
Now gloves, that's another thing. One can never have enough pairs of gloves. And each type of glove should have a stockpile back up to make sure you don't run out of them for at least 5 years. Lined leather work gloves; unlined leather work gloves; mechanics' gloves; light, medium, and heavyweight dress gloves with a variety of linings and outer materials; hunting gloves with various linings and outer materials; winter driving gloves (for which you can't beat unlined deer or elk skin work gloves); and boxes of latex gloves. I think that about covers it. I must have at least 3 dozen pairs of various types of gloves (not counting my two boxes of latex gloves of course). I KNOW I have at least a dozen pair of unlined leather work gloves, about half of them brand new, not counting the two pair dedicated to winter driving. I once walked into a big box store with one of my (then teenage) sons and a friend of his and about 20 feet into the door my son said to his friend "Oh ***, he's heading for the gloves. Now we'll never get him out of here".
