Never heard of dogschnit oil- seems all the major brands "meet or exceed specifications".
Up until about a year ago all my stuff ever had was conventional oil- I do have synthetic in one of the Tempos, I guess as a test. I usually use Halvoline or even Wallyworld SuperTech oil, but if something else is on sale with or without rebate my stuff gets fed that too.
The last 40 years of doing that (in addition to ignoring the "severe service" "traditional" change interval of 3000 miles) has shown to me that my engines have had no lubrication issues even though where I live they'll see -40F to +100F ambient temps; what happens is that road salt kills the rest of the car way beforehand.
In the past I've spent time digging around BITOG; biggest thing I learned was that yep, there are a lot of recreational oil changers in this world.
P.S. I don't own any of that uppity VW/Audi ****; I'd agree if you want that garbage to live you better use their uppity oil in it too.
