Unless it's only sold in quarts (such as most ATF) or economically advantageous I never buy individual quarts because it's usually at least twice the cost per quart over bulk oil in 5 qt. jugs. I'm puzzled how people don't have space to store a single jug of motor oil when buying those individual quarts costs 2x as much as a jug of the stuff. Would you buy individual cans of soda? Or a 12 pack? A quart is $5-7, a jug of 5 qts is $13-20. The math isn't hard; neither the economics nor the measuring. And not having any on hand is equally bizarre. I've got a decade worth of oil changes on hand.
The great oil harvest of 2020-21 has been good to me. It started with the dip in oil prices in 2020, there were a lot of oil sales. Packed in a few hundred qts of the good stuff, about $1-2 per qt. To my surprise, 2021 has been even better to me; in spite of apparent oil price increases and obvious shortages on shelving at Walmart, they are clearancing out oil at a spectacular pace. Their Chevron Supreme at $8 per 5 qt. jug, yes please. I bet I have 20 of those now. It is truly bizarre.
Hit two local Walmarts again, to treasure hunt for their remaining clearanced $6 per jug Quaker State high mileage, and found five 5 qt. jugs. This is on top of cleaning out all the local Walmarts of hundreds of quarts of the stuff at a little over $1 per qt. Most seem to have a few more that surface after a few days so I've checked back when I return. Sure enough, they turn up on the shelving, and then go right into my cart, thru checkout and into my trunk.
I've cleaned out every Advanced Auto Parts of all their Carquest fluids which they have literally given me, hundreds of quarts worth in both 1 and 5 qt. containers. I estimate AAP just handed over $1500 of product to me this month. Perfectly good, brand new, beautiful, lubricants. The bizarre handling of their transition to Fram has led them to just dispose of all oils 'no sale.' Cleaned out the ones locally. Stopping in one today, found 2 more qts. hiding on a shelf and they gave them to me.
So, I returned today with 27 qts. of motor oil and ATF for a whopping $32 with tax. For just today's AAP and Walmart haul, normal retail, it should be noted, would have been $20 x 5, plus $7x2, or $114 or so.
The rebates have been stout as well, with the Castrol and M1 healthy rebates fulfilled. Another 20 qts at about $1.50 each.
Now, I'm just waiting and watching for the next clearance; will it be Castrol or Pennzoil?
