Oil color...normal or is something broken

Fuel is getting by the rings. The longer the oil sits in the crankcase, the worse the smell and rancid it becomes. Changing oil regularly is not just a thing of miles used on the oil, but also time, sitting or running. The oil thins out and will squeeeek paste the rings.

Try some new 10-40 in there and run it, don't let it sit and idle once in awhile. Drive the car! It really is a use it or looose it thing.
