Back in the early 2000s, i worked in a Walmart TLE. We had a guy that was a traveling mechanic for travel trailers ( think axle bearing roadside replacements, brakes, etc) that was a regular.I think Im pretty much done overpaying for Mobil1. I am currently running the walmart brand oil ($18/5qts) and the truck seems to like it fine. After that its the delco stuff until I am out of that.
He had a maroon Astro van with the 4.3 with a documented 500k on it and a purple and white 96 f150 with the 302 with 400k on it. Both ran SuperTech oil and Wix filters. He changed oil religiously at 2500 miles, because he hated going over 3000. And as he would say, " 500 miles? I did that yesterday so better safe than sorry ".
So, it is my experience that post 1980s oil doesn't vary brand to brand as much as companies like to make it seem. Now...there are exceptions and maybe if i can find time, ill post up the site that does independent testing and tells you what brands to avoid. I.E. DG, certain no name gas station oils.
