True, but I've been running synthetic since new, so I doubt that's the problem?

So your saying that the Valvoline and Mobil oil you used in 3 of the 4 oil test was synthetic? You do know that the other brands of synthetic oil are made with 80% or more group III crude oil where Amsoil is made with group IV & V synthetic base stock? Thus the other brands are not in the same class as Amsoil or even Redline synthetic oils and should not even be allowed to be called synthetic being at most they contain at best 20% PAO synthetic base stock.
