Try running a bottle of VSOT, it caused my 3 vehicles with catch cans like above to dramatically decrease the oil amount that was caught. I posted my findings in more detail in the general auto section today. I also use the same style catch can as the above picture. When I first started I could get the above in about 1K miles, now I can't get half that in 4K miles. I used the VSOT with 5W20 so it wasn't the effect of thicker oil that helped. Also I found the oil stays clear much longer now.
