A bunch of us chipped in to have some very sophisticated lab work done. See the #2 and #3 stickies at the top of this sub-forum. Lab results <b><i>do</b></i> make it fact. The green stuff is definitely not G-III. Probably the same for the gold formula, but there is some lingering doubt, as it's additive package is distinctly different. I'd say that the probability is that the base oil mix in the gold is probably quite similar to that of the green formula.
