Less emission, more efficient less combustion/oil contamination.
I watched the OHC CSRV video...reiminded me of a bad infomercial. Anyone else get that feeling?
Yea I see the fact of less contamination, but oil still breaks down. Heat/cool cycles, condensation and bearing material still have a factor in the longevity of oil.
Agreed about the video. I always wonder what they're trying to draw attention away from.
