Funny how all the epa tests and all mpg tests are done with 93 octane. I wonder why. How many centuries old is that quote? Or are you too scared to admit that?
my brother in law sets up some of the testing for FCA (ie Fiat/Chrysler). they do that because 93 octane is commonly the gas available to them that is ethanol free. the ethanol free gas gives the best fuel efficiency. it has NOTHING to do with the higher octane.
