Why is everyone on Amsoils nuts? Is it really that good? I read an article from SportRider magazine that puts Maxima Maxum(semi-syn), and Maxima Maxum Ultra(Synthetic) above Honda HP4(semi-syn), Yamalube(semi-syn), Amsoil(syn), Bel-Ray EXS(syn), Castrol R4(syn), Mobil MX4T(syn), Motorex Power Syn(syn), Motul 300V Factory(syn), Silkolene Pro 4+(syn), & Torco T-45R(syn). Maxima Maxum Ultra boasts the highest antiwear additives per/PPM. Maxum Ultra(syn-4800ppm) & Maxum(semisyn-4900ppm) had the highest by a landslide. Next was: Motul 300V Factory(syn-3200ppm), Motorex(syn-3000ppm), and Belray T-45R/BelRay EXS(both syn-2700-2800ppm) Amsoil(syn) came in at about 2600ppm. I just go by what I read. I'm not too educated about Amsoil other than that it was rated #2 in automotive with Mobile1 in first place.
