AMSOIL is a very good oil but Redline also has test with it vs AMSOIL and it wins those...
SOme of the AMSOIL tests have been accused of not being representative of real conditons.
Also it goes with selection of viscosities'.For example if memory serves their 4 ball wear test is run at 40C (approx 100F) but motor oil temps in a running engine are typically around 100C(212F)You an always pick and choose parameters if you do the publishing.AMSOIL is one of the better syn oils out there but it doesnt walk all over other POA oils like MAOBIL1, Redline (actually group V), German Castrol (only in 0w-30 which is PAO also).
