expensive although it does include shipping.

Yeah, it sure is expensive. I can buy a case of AMSOIL 0w-30, which is just as good, if not better, and have 12 quarts for about the same price.

The Amsoil is kid of a different oil though. The Mobil is more for racing with high levels of zdp.

Where can one see the oil analysis of these M1 racing oils for the ZDP and other constituents?

You can buy 15-50 in 5 qt jugs at walmart for about $24 a jug. $20+ a quart for those 0-xx weights is nuts.

Higher compression ,,needs better oil !!!

0-30 is the way to go .
Or 25W50 Penzoil Racing !!!

The 15 + 20 / 50 is regular use oil ,,not for tricked out high RPM engines !!!

I have been told by a reliable source that Mobil makes Amsoil base and they put in their own additives.

Aren't your a dealer of Amsoil? What is the retail price of a equal Amsoil product including shipping?

Amsoil doesn't refine their own base stocks, they have to but them from someone.
