Amsoil, simply was not aware that their fluid is close enough to the shell M-1375.4. So, it looks like they contacted Ford about Mercon SP when they noticed the similarities, but not shell. I don't care about the "low end" comment. These people you talk to over the phone, are typically sales reps, and have questionable expertise.

Obviously very different from what I was told. You probably talked to the general shell line. I called up their manufacturing facility in Houston, Texas, and till this day, they are manufactring Mercon SP.

So in the same manner, what is the difference between Lifeguard5, and pentosin ATF1? Here are the Two MSDS's for you to compare:

If they're re-babeling this, why is it hard to believe, that what they're re-labeling as LG6 isn't being sold to other markets? I'm not even going to ask what the price difference between LG5 and pentosin ATF1 is. Most E46 owners, didn't even look like they cared either, they saved their money further, and bravely used Redline D4 ATF! Since the dealer wanted them to give an arm away to ZF for re-labeled fluid, or never change their fluid at all.

Looks like that quick lube site, copied the info off the original site, in its entirity. Both Fluids are still listed under the institute's ASP15, so whats your point?

ASP15 Automatic Transmission Fluid
Ford Specification No. M2C 919D
Mercon SP Fluid Part No. XT-6QSP
Shell ATF M-1375.4
ZF 6-speed Automatic Transmission Fluid, Shell M-1375.4

People are trying to spread the word, to avoid overpaying for the same thing.
