  1. I have used Gyeon Q2 leather shield. It is a ceramic coating made for leather.
  2. 2020 Sierra Denali and 2011 Sierra SLT, both have 6.2 Litre engine.
  3. Tried 87 and 93 octane, not hauling heavy loads. I get the same gas mileage with 87 or 91 octane.
  4. Has anyone tried a wheel spacer, say 1/2 inch?
