Just curious if anyone has used the restore engine treatment in their GN? I seen the videos posted cody the car guy but? My GN has about 92,000 miles barely gets driven about 3 to 4 hundered miles a year and I use 10W-30 royal purple? If the car sits for a very very long time it will smoke from under the hood bad but then clears up after the first drive (no bad smoke from the tailpipes). I have had the valve cover gaskets replaced about 4 years ago with the cork and same with the pcv valve. I guess my question is it safe to use the restore engine treatment with the royal purple synthetic oil as glen from highway stars has told me to not use the zddp for my stock engine because the RP has all the zinc I need. When I drive it occasionally in the summer months it doesn't smoke only from the first startup when it has been sitting all winter and sometimes mid fall. I have had one occasion where it seemed like smoke was coming into the passenger side cabin that was somewhat faint but could see it a little down in the floorboard area? Thanks
