The SuperTech 5w30 Full Synthetic was mentioned here as "a good oil" by Bob and retails locally to me for $17.47 for a five quart jug. That's pretty good in my book. Next time I need to add a little oil to my collection in the garage I'll pick some up for my car.
In reply to Bob the REAL oil guy. :
Good to know. I run 15W-40 in just about everything except the race car (which gets the M1 15W-50). I usually buy the 2 gallon jugs of 15W-40 at tractor supply or walmart.
All of my cars are either flat tappet or diesel.
Thanks for this. It confirms what i believed to be true, and have been using for the last gew years.
I feed the Jeep a steady diet of 5W-40 synthetic diesel oil (usually Rotella T6 or Delo 400, whichever is on sale) and have been for a while at this point. It works year-round in there (from a viscosity perspective), it's not terribly expensive and it takes care of that engine's needs for 6k miles with no issues between changes.
I've been contemplating the new engine the last couple of months and am pretty sure the replacement will have a roller cam. A this point I'm just feeding it oil until it says no more.
The NAPA house brand oil used to be made by Ashland, which makes Valvoline. I don’t think they still do though. Anybody know who makes the super tech brand?
I did some environmental work for a company that bought an oil formulating facility in Charleston, SC. I believe they are part of Amalie (?). Pretty sure you could get anything you wanted custom blended there if you will buy enough of it.
formulation looks like many of the pennzoil brands, but not exactly.
Snailmont, I'm running a 1991 5.0 HO with a cam in the Fubari as a track motor and I switched from dinosaur to synthetic because of the heat. I had no issues (other than it spraying out of the dipstick a bit until I got the PCV system unclogged).
If the SuperTech oil is like the rest of Wally World Private Label, of which I know a bit about, then they probably put it up for bid to the big motor oil companies. It could even be bid out by Walmart DC, so one DC and the stores that are fed by it could potentially get one manufacturer and the next DC over and its stores a different one. Not even necessarily regional. Or they might all be from the same supplier.
Sam's Choice water in the plastic bottles (PDW), for example, is done by DC. The Sam's Choice CSD have a single supplier.
I have heard of people that have seen the SuperTech full synthetic oil either come off of pallets marked Mobil1 or from Mobil1 shipping facilities. Perhaps that DC was Mobil fed or the whole business was at that time. Or maybe the Penzoil synthetic is made by the same people making it and Penzoil has private labeled their stuff.
I like Maxlife Heavy Duty Diesel 15w40 for budget oil with good Zn. High mileage additives, semi-synth and over 1000 ppm of Zn for $15 a jug at Walmart. Even the 40 wt's are going away from the "cat killing" 
Zinc additives it seems.
I got a great deal on M1 5w50 for my FJ60 that was just rebuilt. It's a 9 qt capacity so I have to luck out on timing for oil that meets what I need (excellent cold properties, as much Zn as possible and a 40 or 50 operating wt at temp) and isn't really expensive.

That's because Warren Performance Products made (maybe still makes?) and bottles the oil and they also bottle other brands. This is how it was 5-10 years ago.
