As per the chart on the Amsoil's website under 0W-30 product page...it shows that Mobil 1 "Extended Performance" causes most metallic wear scar, even more than regular dino 5W-30 Havoline? http://www.amsoil.com/graphs/sso_4ball_400px.gif http://ww w.amsoil.com/graphs/sso_4ball_400px.gif Surprisingly it does not have Valvoline SynPower nor Castrol Edge listed? I wonder why? Mobil 1 EP is the most advanced oil from Mobil to date, if that is causing so much wear, I wonder what should we make of other regular Mobil 1 and Mobil non-synthetic products? Amsoil can not certainly be lying on ineternational scale from their "the main" website, they will get in big trouble for that, so what should we make out of this? Please comment!
