Okay, so reviving the oil catch can theme for a moment. I was under my hood today testing out bulbs on my battery when I happened to look at my Mishimoto catch can that's hooked up the the PCV line. The indicator tube shows that the can is about 1/3 full of oil. The can has a capacity of 16oz (1pt), but I do have it stuffed with stainless steel mesh which will add some displacement. So, I am going to say there's probably between 2-3oz of oil and stuff in there. When I get around to draining it, I'll know for sure, but that's about 1/8 of a pint that was kept out of my manifold. I know that ain't much, but for a NA car, it shows that the can actually does something.
Previous to this, I had only once before found oil in the catch can between oil changes, and that was my last oil change where I didn't use the Nanotech additive. After using the Nanotech for the next three oil changes, I had zero oil in the catch can. I had run out of the Nanotech, so it wasn't added last oil change, and after 6K miles, there's oil in the can again. So, there may be a correlation.
