>>>He also swears from Amsoil that Mobil 1 and Quaker State use used, recycled dinosaur oil as a base from which to produce their synthetic oils (chemically altered to produce the altered molecular structure), and that Amsoil does not use petroleum base oils to make their product (though he didn't know what they do use). Obviously, synthetic oil is a formulated hydro carbon custom made or modified to produce molecular chain length of optimum length and composition to resist oxidation or coking at high temperatures with an additive package.


I think he'd better go back and regroup (or maybe you didn't interpret properly what you heard). Mobil 1 uses PAO Group IV and apparently some Group V base stock, as does AMSOIL.

I believe QS and most others use Group III (hydrocracked petroleum) as base stock. None that I've ever heard of use recycled oil in any way to formulate stocks for their synthetics.
