The camshaft lobes looks fine to me. I'm more bothered by the dark amber colors of the camshaft retainers and the oil gallery.

I'm currently on the Mobil1 0w20 AFE, which I thought was their best top of the line Group IV/V oil. So I guess I gotta shorten that then huh. So what's a good interval to start from? 9 months?
