Could be, but I doubt it. Whichever the case, if they can't be straightforward with me enough that I have to wonder about it, that's reason in my book not to buy their product. The openess of Turcotte in those articles impresses me and makes me want to buy the product as long as their are no technical show-stoppers.
Apparently there are other specs. besides that ASTM D6210 spec. that was referrenced in an article that I quoted (stating that G-05 meets D6210)? I know I saw somewhere in my reading that G-05 is approved for use in certain brands, including CAT - not just saying that it could be used in..., but that it was actually approved by... If I can re-find that reference, I will post it.
