Schaeffer's 5w30 Supreme is 75-80% group 3 and 20-25% PAO, and it shows better specs than Mobil 1 5w30.
Schaeffer's blend is Group II and PAO. And it still can't match Mobil 1's pour point or cold cranking/pumping vis numbers.quote:

True, and I think we over look the importance of the cold cranking number. If most engine wear occurs at start up, M1 is a good choice.quote:

Nope, the 10w30 blend is group 2+ and PAO, but the 5w30 blend is group 3 and PAO. This info comes directly from the head chemist at Schaeffer Oil.quote:

I'm confused...is this a circular argument? You're sadly mistaken, my friend, but you can believe what you wish.quote:

Okay, prove me wrong. Post the name of a Group III motor oil that has BETTER specs than any PAO-based motor oil. (Equivalent grades, of course.)quote:

The head chemist needs to let Schaeffer's marketing department know, then. Their online spec sheet for the 5w30 blend clearly states that it's a blend of PAO and Group II+.quote:

Schaeffer Oil is a good company, but not known for their speedy updating of their website.quote:
