Amsoil Quote:
"PAO composition is a series of chemical processes that are designed to
provide superior lubrication performance over a wide temperature operating
range. They are synthetic hydrocarbons manufactured by a two-step process
from linear alpha-olefins produced from ethylene.
The first step in the synthesis is an oligomerization reaction, essentially
polymerization, with boron trifluoride in combination with a protic
co-catalyst. They are manufactured via Ziegler-Natta catalysts; usually
alkylaluminum compounds in conjunction with organic halides."
Hmmmm..."Organic Halides" - guess what - found in CRUDE OIL. ;)

It's not a true synthetic Jon if it is derived from base crude...and Group-4
isn't 100% synthetically engineered - Amsoil has already admitted to that
years ago.

That is only partially correct. Although groups 1, 2 and 3 are
indeed created from petroleum, group 4 base stock is a true synthetic,
not derived from petroleum. It is created via a chemical reaction,
"in a lab", as you say. (The sanity of the scientists involved
notwithstanding.) :-) Although *most* "synthetic" oils are actually
created from group 3 base stock, some are created from group 4, such
as the original Mobil 1, I think Mobil 1 is group 3 now though.
Anyway, there are no dead dinosaurs in group 4. Group 5 is also a
true synthetic, though I don't know of any oils using it as a base
stock, group 5 is usually used to formulate additives.
A related factoid: Oil companies are allowed to call "synthetic"
oil based on group 3 base stock a synthetic because of the Exxon/Mobil vs
Castrol lawsuit in which Castrol was able to convince the court that
group 3 was of sufficient quality to market the oil as a "synthetic".
(Mobil 1 was using group 4 which is a true synthetic and Castrol
Syntec was being made from the less expensive group 3 and undercutting
Mobil 1 sales. Exxon/Mobil sued Castrol to stop them from calling
group 3 oil synthetic, but Castrol won.)
