Ok, maybe I am retarded but I wasn't able to find much on Supertech Synthetic. At the wally world it is only pennies more expensive than the most expensive conventionals, like PYB, ect. How does this motor oil compare with additive packs? What name brand group III is this stuff most comparable to? I am thinking of using this in place of conventional in my 4.9 F150, heck I'm even considering using it in my Corolla and Avalon instead of M-1, due to the fact that I only do 5-6,000 mile oil changes.
