I keep 4 or 5 gal on hand as I have diesels, cub cadets, and the two old classics. I get it most often at Rural King as they generally have the best price. You may not have a Rural King, Tractor Supply, or Farm and Fleet in your area, but try a 'farm store'.
Brian - I was at our local Walmart just a couple hours ago and passed by the auto parts section and saw it on the shelf. Even with the abundance of empty shelves these days, they always seem to have the CJ-4/CK-4 SuperTech 15-40 at least at the Walmarts here in Arizona.

I just happened to be at an auto parts store and they said they have trouble getting it. I don't have a convenient Wallmart nearby but I'll make the trip. I always add Camshield anyway.
I know that all oils with the cert are the same and pay attention to the oil threads and articles SWCDuke
However, to OP comment, I have a new Kubota and was going by the dealer & warranty advice to search it out recently (I know hogwash...)
My Eastern PA region is dry of all T5 & T6 Rotella and most diesel grades of any brand: WM, Napa, TSC, FLAPS.
I found some at HomeDepot of all places. I was looking for the T6 5W-40 for winter.
I’ve said it before, and I’ll say it again…. determine what you’ll need for proper/correct C2 maintenance, and acquire a lifetime supply, while it’s still available. And I don’t just mean motor oil. God knows what may, or may not be, available down the road.
After my previous post, I went crusin the ol inter web and found this. A list of popular oils with their listed zinc, phosphate, and zddp content. I was surprised about a few that I saw, some more, some less. Enjoy. https://www.autorestomod.com/oil-zddp-list.html

The post says the information was compiled in 2015.
I have used Chevron Delo 400 LE (CK-4), but recently the formula has changer. Zinc was in the 1400 ppm range, but has been reduced to 830 ppm.
Just because it says CK-4 does not indicate the antiwear ingredients are there in numbers we like. Rotilla still looks good.

it’s for fun - I saw the date. I agree. Some are still the same, but several have been reduced. One should always check and read the MSDS sheet for whatever you are going to use.

Some C-category oils have reduced P and Zn, but are fortified with Boron based anti-wear additives. ZDDP is no longer the only game in town. The P limit is still 1200 ppm and the C-category wear tests, which are tougher to pass than the S-category wear tests have not changed.
There's no need to travel to Walmart for their oil. They'll ship it to your home. I ordered enough that the order hit the minimum to qualify for free shipping, and now I have a few gallons in inventory for future use. Couldn't have been easier.
