The 10 is giving me regin problems every other day, and the pete works great, can use some fuel savings, it gets 5.9 to 6.3 running from Sacramento to los Angeles. Would like to improve the pete and life span, kw fix and mandate, neither 1 uses oil,

I would suggest contacting Rawze, Unilevers, and/or Gearhead here on this forum.
