No you can not......octane is the measurement of the volatility of the fuel......the higher the octane the slower it burns.......putting high octane fuel in an engine designed for regular octane fuel is just a waste of money.
Pretty sure Ford factory warranties start at “0” and expire at 36,000 miles or 36 months......now if you buy an extended warranty then yes they go from current mileage to what ever mileage term you chose.
Yes it was.......found a couple of non FE that have the same priority number as mine and were reserved 3 days after mine....7/14 was my date and those that reserved on 7/17 have gotten their production dates already....all I can guess is that they are PB.
