Well - Chickn Little it is

[ssj4]

Went to an AZ today (one that had been out of GC for months). Thy had some M07 GC on the shelves.

Now I have 80 some quarts stockpiled, and at least my first UOA on my first fill of it didn't seem all that stellar in the Iron department, plus it consumed 1qt per 1800 miles.
We will see how the GC Green + Ceratec does, then after my current fill (Lubro Moly VS 5W-40) we will see how the gold GC does.

I'm thinking maybe a 30w is indeed too (thin) for my app.

It seems GC has alot of iron in it before it ever gets in your engine. You need to take that into account when you look at your UOA.
