Hey guys. I did a search for this but got nothing. When I get on the skinny pedal to blow some soot, I get a cloud of brownish-grey smoke almost like rust. My daily trip is 100 miles highway with 5 mins on the back roads. I noticed some power loss a while back but figured it was the winter mix. I use 16 oz. of PS white bottle every fill and changed the fuel filter already(9k). Other than that everything is fine. Just miss my mini cloud of black death.

 

the PS maybe doin more than you expect. things may have cleaned up.
