3.6 in A-body

You’re getting 25-30 mpg and approaching 13’s?
And what’s the problem?
the least I get in my wife's Cherokee with the 3.2L is 25mpg. Of course that's with an 8spd auto, but you have a 6spd stick, so I think that's not that dissimilar. The big difference might be the weight , that's why I asked.
