exactly the point. all that BS on that webpage is intended to hide the fact that they are a group III oil. check this page out.

http://en.wikipedia.org/wiki/Synthetic_oil

specifically, this portion:

"Hydrocracked/Hydroisomerized = API Group III base oils. Chevron, Mobil, and other petrochemical companies developed processes involving catalytic conversion of feed stocks under pressure in the presence of hydrogen into high quality mineral lubricating oil. In 2005 production of GTL (Gas-to-liquid) Group III base stocks began. The best of these perform much like polyalphaolefin. Group III base stocks are considered synthetic motor oil in North America."

you wanted evidence, you got it. i really doubt mobil would spend tons of money to develop this process and NOT use it. here's what amsoil has on their webpage:

"Currently, each AMSOIL lubricant is formulated with the synthetic base oil or combination of base oils best suited to that lubricant’s application demands. They are optimized using the most advanced premium synthetic base oils. Although AMSOIL has publicly stated that its XL motor oils are Group III based and its other motor oils are PAO based, specific formulary information beyond that is exclusive and proprietary. AMSOIL views synthetic base oils the same as it views additives. Each has its unique set of properties, and AMSOIL, based on its extensive experience, combines them differently for superior performance in any given application or operating condition (gasoline, diesel, racing, transmission, gear, extended drain, extreme temperature, etc.). "

so their XL line is group III hydrocracked, but every other oil line is PAO based, which means group IV. the proof is in the pudding, now someone close this thread, PLEASE!!
