This has been seen on here before. That is why I went w 3k miles oci's. It started burning on my Element between 3-4k miles. Element did not burn prior to use, was using it to remove heavy varnish. Stuck rings were fixed prior to VRP being made.Oddly enough, my van is starting to burn R&P. This is my second run at it. I’ll go back to MaxLife or Havoline in the 6qt box.
