It can be made quite good if you use some the "brew" ideas shown here. Using Lube Control, and #132 Schaeffers moly EP add.
See previous posts by MoleKule on this subject.
If you don't want to diddle with mixing the Brew then for the Money I suggest Schaeffers Blend.
If you must hav a "real " synthetic Redline is a good choice , but you will pay for it. They have a new 5w-40 that recently impressed me in a VW 1.8L Turbo posted in the UOA results section.
Amsoil is a solid oil and probably superior to any other in really cold Climates. The Drain interval recommendation is marketing to sell a overpriced oil. I say that with all due respect to the Amsoil guys here who all top notch.
