I should update what some have been discussing. The Owner's Manual initially states to use Premium only, but then there is a supplement or correction to the original manual that states Regular fuel may be used, but there may be a drop in performance.
I plan to use premium, I like all the power I can get, and for the price, it is worth it. I only have about 200 miles on my JX, but I am right around 19-20mpg, and of course this should improve after the engine breaks in.
