Well... Thanks everyone for the effort y'all put into answering and commenting on this line of thinking I had developed on the Amsoil brand. I'm sorry that some of you have come to keyboard blows on this issue, but I've noticed that this topic sometimes does.
Some of you have corrected me on my thinking that Amsoil was in a class by itself in the way it formulates its' engine oil. Although it makes me feel like a dope, I also feel like I've learned something that will save me money going forward. It's nice to have the affirmation, that I haven't been using oil that is bad for my engines, but it seems that I can get similar, if not better, engine protection from some cheaper (cost) brands; namely Mobil EP or maybe Pennzoil Ultra, especially if they are on sale, which they often are at our Canadian Tire stores.
Would you guys also agree that Amsoil's Signature Series oils are bettered on a performance and cost basis by other oils on the market?
P.S. to those who've asked, the Canadian Preferred price for 5W-30 OE is $9.99/qt. Sig Series is $15.29/qt
