+1 Thanks for saying, you beat me to it.
My personal answer would be that i like XOM stuff more than SOPUS, and id save the 75 cents.
its not like its bad oil.
Ive never been too big on PYB a.k.a. QSGB. People say they have less MPGs than other oils, and are likely on the thick side. Also, PYB is the only SN 20W-50.... use 5W-50 or 0W-50 if you need that grade.
Historically, ST has been a decent oil and it get's the job done. I have always liked SOPUS products though and would rather spend the extra $.15 a quart.
PYB != QSGB. They are two different oils.
Regarding thickness, the SM info I have on each oil indicates QSGB 5W30 is 10.5cST @ 100*C and Supertech (XOM) 5W30 is 10.6cST @ 100*C. The XOM oil is thicker, but not enough to notice in your engine and probably varies between batches. The SN specs are probably similar.
As I said before, ST was awesome for $5 a jug vs the name brands at $8 or $10. It just doesn't make sense to me to not buy name brand oil for $.75 extra. If Wally dropped the jug price a couple bucks, I'd be back to it.
