Which USA based oil company to go with?

You have normal vehicles that would do fine with oil from normal companies - Shell, Castrol, Mobil, Valvoline, Pennzoil, etc. Use the grade the manufacturer recommends and change the oil every 5,000 miles. Your engines will thank you.

You can pay more, a lot more, if you want but I don't think it will make any difference.

We've had the challenge on "Bob" several times to identify even one engine that had failed because of a lubrication issue that had received oil changes with mainstream oils at reasonable intervals. Still waiting....
 
Given your short OCI intent, you might as well get the least expensive lube. Shop by price; you'll waste less money that way.

Also know that ALL the companies you mention you're considering source their base stocks from the majors, which means some of your purchase money is going to the multinational behemoths anyway. It's not like Amsoil, Shaffers, RP, HPL or any other boutique lube maker owns their own refineries, etc. They are blenders.

In fact, I'd recommend any ST product you feel comfortable with. 5k mile OCIs are not a challenge in your applications. And Walmart is as American as any other company you are considering.

I did have a 2008 Saturn Outlook with slightly more than 100,000 miles that had a rod bearing failure in 2016. I had changed the oil and filters myself at 4,000-5,000 OCI's using Pennzoil synthetics and Fram/Wix filters. It was my wife's car and had been problematic from almost the first day we bought it. The choice the mechanic gave us at the time was to put in a used engine for $6200.00 or a rebuilt for about $8000.00. We didn't think it was worth it so we sold it off to PEDDLE.com. That all said, I don't know if it was oil-related or just bad luck. I have wondered though, what might have happened if I had been enrolled in Pennzoil's Warranty and what they do to determine cause.

Too bad you didn't tear it down. Could have been lubrication related but just as likely not.
 
SuperTech is made by an American company...:unsure:
I was going to say Warren is an American company right? We got like 4 gallons Kirkland signature at Costco because a box of 2 gallons each came to like $20/gallon which is more than $10 cheaper than the Mobil 1 0w40 I usually use.
 
I picked out dog food cause the beautiful vizsla on the bag 🤣. I have a vizsla so easy enough right?

My vet gave me the *** look.
I just learned that I mistakenly called a vizsla a "red dobermann" the other day.

No wonder the woman owner gave me a funny look. I thought maybe she just wasn't interested. I was "directly rejected."

Beautiful dog. Give yours the good stuff !

If you're going to change it every 5,000 miles, in those vehicles, then, just about anything will work, I would think.

Why an American company? Is this about the best oil for your car? Or just supporting an American business? Does the size of the company matter, too? Are you looking for a quality formulation? Or just location? Is customer service a factor for you?

If you help us understand your goals, we might be able to come up with some solid recommendations.
yeah good question. Looking at your cars that the oil is going into why not use:

 
Mobil, Valvoline, and Chevron are the only big 3 that come to mind.

No need for a gourmet oil in this situation.
 
Tell us you have no clue while not telling us you have no clue.
What about his post steers you into thinking he's clueless? What he said is completely accurate and is great advice. A point to the contrary, insisting somebody needs a boutique oil for his operating conditions, would be the clueless take.
