I don't know where you get your information, but Amsoil makes Group III and group IV synthetics. They only made "real synthetics" from the early '70s until the '90s where some of the lower-grade "synthetic" offerings from other companies caused them to start selling the Group III stuff. Same with Mobil 1, used to all be the good stuff, now they sell both grades for marketing reasons.
