My previous experience on 2 other GM cars leads me to believe that topping off the oil, even with syn oil at $8 a quart every month is about $100 a year. That will be less than any engine repair costs for the remaining life of the car.
I apreceate the info everyone, I have seen a video on the catch can and I can see just topping it off and checking every week is the least expensive route. I do plan on trading the vehicle in for a new car or truck in about 2 years.
What I did was, I went to sears and bought 2 of the oil/water separators, spliced those inline one on the dirty side and one on the clean side. After a few thousand miles my intake manifold and air intake tube are oil free. Good thing is these separators especially the dirty side catches ALOT of oil, the bad thing is I still have to top of my oil like I was before lol.
