Conventional oil hard to find?

Kids are on spring break so I changed their oil & filters.

Bought Costco oil but to my surprise they no longer sell dino juice.
Bought Mobil 1 oil filters at Walmart but they also had no dino juice.
Went to O'Reillys but their conventional was more expensive than synthetic.

I had Costco look up who had conventional oil and it turns out they
discounted their last cases of Chevron 10W30 SN & 10W40 SN conventional oils
to $9.97/10 quarts more than a year ago and haven't sold any conventional
motor oils since then at any Costco in my area.

Huh?
Since when is conventional oil hard to find in bulk?
Is this a new thing?

I'm not complaining or even asking whether the $25/10 quarts Kirkland fully
synthetic 5W30 SP oil is good or not as I know all about synthetic oil
advantages & disadvantages over conventional gasoline engine motor oils.

I'm just asking if you've also found it hard to find conventional oil by the
case at good prices (which means at your local Costco or department store)?

If it meets the required API spec, it's good enough for me.

Stores here have lots of dino oil.
However, with full syn at $3 per qt and dino at $2.50 per qt I always
get full syn.

Did you check your local Costco?

They showed me the green screen of their inventory.
All the Costco wearhouses around me long ago discontinued dino juice.

Maybe it's just Costco that stopped selling bulk dino juice?

There are other stores in this world besides Costco.

Do those other stores match Costco sale prices?

What matters for motor oil that is frequently changed is only three things
(1) price
(2) API quality (but it's really hard to find poor quality oil anyways)
(3) Viscosity range (which itself only matters most in the extremes)

Conventional SN has to be about half the price to compete with SP synthetic
(because synthetic lasts about twice as long and is a bit slipperier too).

I bought the one case of API SP fully synthetic 5W30 because I needed it but
I generally buy a few cases when Costco gasoline motor oil goes on sale.

If we assume Costco sale pricing will perhaps be around $2 per quart for
full synthetic API SP motor oil (of varying viscosity ranges) then the
comparison price for the API SN dino juice has to be about $1 per quart.

At anything more than about $1 per quart the dino juice won't be worth it.
It does't matter what store.

All that matters for motor oil that is frequently changed is price & API
quality & viscosity range - and not the store from which you bought it.

I don't go to Costco.

Yes but can you find it at your local Costco or at around $2.50/quart?

BTW, the Kirkland fully synthetic 5W30 motor oil I bought is API SP
(although this heating/cooling test showed some models are API SN Plus)

They tested the oil for a bunch of things that matter for motor oil.

They heated it. They cooled it. They looked for wear scars in bearings.
And they ran it in an engine & sent it out for chemical testing.

According to this video all three of these oils are the same
(and all three are definitely made by the same manufacturer)
https://youtu.be/l9il_piyuT8?t=668

Amazon Basics
Supertech
Kirkland fully synthetic

They're all the same oil made by Warren Distribution in Omaha Nebraska.

Not only does it meet the API SP specification but it also meets
Dexos 1 Generation 2 approval (which I'm not yet sure what that is).

Where do you get full synthetic oil at API SP quality for ~$2.50/quart?
