Recent issue of the Amsoil Action News has a direct comparison of the two oils with the following tests being reported on.
Noack Volatility (ASTM D-5800)
Four Ball Wear Test (ASTM D-4172)
Flash and Fire point (ASTM D-92)
Pour Point (ASTM D-97)
TBN Amsoil is 12.35 Mobil 8.45 (which one depletes faster?)
Naturally Amsoil comes out on top, at least in the numbers game.
What I want to see is the same engine or two duplicate engines same mileage on both and same miles on oil running both oils and oil analysis results and every wear metal and additive etc. published for REAL WORLD results. These bench tests, although indicators, are not real world. Ideally for me I would love to see these oils compared in a 1999 Toyota Camry V6 engine!
