Why?

89. Not to expensive, not to cheap.

I use 93 octane all the time and get 23-24 mpg around town and it runs better .

None of the above. 91.

i hope you blown motor users do use 91 or greater octane.

i normally use 92 runs much better still pull down 22mpg in town

i run 92 in my Bonnie, 94 very rarely she seems to run best on 92

Most of us are smart enough to read the fuel requirements stenciled on the fuel gauge.

Premium ONLY BABY! My Car deserves THE BEST! That & Since I'm only running on 5.5 Cylinders right now until spring, I need all the power I can get!

I agree with the Demi-God! Nothin but the best for my ride. I've tried the lower octane and it runs like crap with anything less than 91. I usualy get 93 but if I can find 94+ I will put that in too sometimes (hard to find close to my house).
