Well, the higher the octane, the more resistant to ping your Jeep will
be, but the question remains whether or not you need 93 octane to do the
job. If the 89 octane eliminates it, then you're good to go. If not, you
can try a 50/50 mix of 89 and 93 or try all 93. The goal in the end is
to get the most distance traveled with the least amount of money, and no
engine damage. Right now where I live, 87 and 89 are the same price for
whatever reason, so I just use the 89 octane.

You know, this goal description is the polar opposite of my entire life
in relation to the automobile. :)

Hi Chris,
I live just south of Green Bay, and the Kwik Trip stores around here had
87 and 89 at the same price, but the 89 was blended with up to 10% of
that ethanol crap (imo). I don't really look at the prices anymore; if
I need gas, I buy gas. It's like milk. I have no clue how much a
gallon of milk is. I just know that when one jug runs out, I need to
buy another. I do look at ethanol content though.
