I agree! If PYB was a syn/blend, SOPUS would have marketed it a such, the way Motorcraft has marketed their oil(5W20/5W30) as a syn/blend.
PYB is a good Group II/II+ motor oil(I don't really know what II+ is) held in high regard here at BOB's as well as other sites on the web and also, PYB has a good additive package that contributes to it being a good oil. Use it with confidence!
Even if PYB did have in it some Group III(just a smidgen), they're not saying so as not to infringe on their own syn/blend oil sales...Does Pennzoil even have a syn/blend oil on the market? I know that they once did and I have seen a HM oil! And we all know about PP and PU!
Anyway!...
