All Amsoil XL series is group III to get API approval:

"AMSOIL Changes XL-7500 Formula To Enhance Oils, Stay Competitive

Q: AMSOIL will be using a different formula for its XL-7500 Motor Oils. Why did AMSOIL change the formula?

A: Our XL-7500 oils are the oils of choice in the retail oil change market, and primarily because of warranty concerns the customers in this market require API-certified oils. In order to obtain API SL/ILSAC GF-3 certification and still remain cost-competitive with the other oils sold at retail oil change outlets, we had to change to Group III basestocks. To obtain API certification with our top tier basestocks would have priced our Dealers out of the market.

Q: Are Group III basestocks synthetic?

A: Yes, they are synthetic. Group III base oils are highly processed oils and were classified as synthetic in 1999.That year, the National Advertising Division (NAD) of the Council of Better Business Bureaus ruled in a complaint by Mobil Oil Corp. against Castrol North America Inc. Castrol claimed its product, Syntec, was a synthetic oil even though it had used Group III base oils since 1997. The ruling by NAD said Castrol presented evidence that constitutes a reasonable basis for the claim that Syntec, a Group III based formulation, is synthetic motor oil."

Yeah, not a woman, just a fan of Megan.
I have a friend that's an Amsoil dealer and at one time he gave me a quick rundown of their different series of oils--and I seemed to remember that the XL series was group III, ACEA A1/B1, and API approved, so I looked it up to be sure. I'll go ahead and stick with Pennzoil Platinum, over the XL.
