The only thing I noticed about the SuperSyn was that there seemed to be a little brown fall out at the bottom of the 5 qt jug. Never thought I had to shake oil before use. I guess it's the wear additive. Not a lot down there, so I don't really care. Otherwise it seems the same so far. We'll see what gas milage says but I'm fine with it. All it is is Tri-Synthetic with a new additive AFAIK.
