Their advertising with things like "First in Synthetics" (Amsoil was the first synthetic oil to obtain API approval followed by Mobil -- first synthetic fuels/lubricants were synthesized in a German lab back in the early 1920's, and then later in the US); extended mileage claims which are not applicable to all vehicles (TBN values can drop fast depending on what's going on in the crankcase); and the 4-ball test that I talked about earlier. Crankcase oils should be tested on engines which is how it's done to meet API SL/SM/SN, ILSAC GF-5, ACEA A3 oils.
It's most likely a good oil since many people use it, but there are also many other good oils out there. It depends on what "good" means to people.
