But with about ~3000miles of absolutely no track/off-road use on fully synthetic oil (as recomended by the factory) I have noticed the oil going dark/black.
Now, there might be other factors involved due to which this might be happening but I just like to be safe than sorry 
Tranny/diff fluids can probably wait but who cares once the car is on jack stands, might as well go on and complete the full circle 
Also, were you on mnsubaru? |
I have the Perrin bigmaf CAI and haven't noticed any differences in the color of the oil. That being said and as you stated, an oil analysis is the only way to determine if it's worse or not. I run either amsoil signature series 5w30 or 0w20.
