I was unable to display the above link, why is there an .exe extension on it?
I don't think Specialty Petroleum exists any more, I think it was closed down when production was shifted to WPP as production went from SJ to SL. I think you're pulling the U.S. brand name that was used pre-1999? For some reason Wal-Mart kept the Tech 2000 brand name in Canada rather than shifting it to Super Tech. For all I know, Safety Kleen is simply the bottler, I doubt if you could recycle anything and certify it as Group III or better.
As far as the Wal-Mart= crap comment, please explain further. The ST stuff has been far from great but seems to get the job done in used oil analysis-- much like Valvoline. We have no GF-4 used oil analysis or VOA's as far as I know. Given the difficulty of measuring just exactly what's in an oil given all the new additives, I'm not sure how you could definitely give a statement as to good or bad.
I'd assume that any SM oil would be pretty good if it really met the specs. Do you think Walmart is cheating? How would they do that?
WPP (and I suppose its Canadian counterpart) are probably picking up stock and additives where they can on the open market. ST is a Wal Mart brand name, not a product. It's WPP in most (but not all) parts of the country. It used to be Specialty Petroleum.
What about Havoline?-- that brand name has been passed around just as much. What about Consumer Reports assertation that Shell was totally different products in different parts of the country?
