Jimmy,
FWIW, I have to agree with Brian on the octane issue. My Dak (you remember
it don't you ;)) has a hotter cam, ported and milled heads, larger throttle
body, ported M1 intake and the MP PCM. In my area I have access to all
grades of fuel, with or without ethanol. I've found that my Dak is a few
hundredths quicker in the quarter mile using 92 octane instead of 94. Sooo,
I figured, why waste the money! We've also found the 87 octane works best
in our Jeep and Stratus at the track.
I also choose the non-ethanol stations for all our vehicles. I read on some
fuel brand's web site that their engineers openly admit that ethanol will
adversely affect fuel mileage to a small degree. Since around here it all
costs the same, I tend to stick with non-ethanol although I've occasionally
had to use it on a long trip.
