I guess I did on this test #2, I was doing this one on my own , but I wanted to see if it would improve the oil consumption. We did a legit one the first time (oil consumption test) and the area service manager said that they would have to seal up the oil drain plug to make sure no one was tampering with it and do it again, so when the next oil change is due I will take it back to the dealer and just use Mobil 1 with no additive, and see what happens from there. Also I have went to the fixed oriface PCV, it helped out a little with consumption but not much , I guess I need to get a catch can.
