Though I agree that a 1-2mpg increase is small, I don't think the real intention with this engine change was fuel economy. It was directed at fixing an engine that didn't have the umph that 'some' people wanted.
I myself have no real significant issues with the 3.8 as I bought a Jeep and not a car. When i'm wheeling my 4.10's do what I need em to do.
No one should buy a Wrangler if your looking for good fuel economy!

I don't understand why everyone is confused. The new engine is much more efficient since it has ~80 hp more without sacrificing a single MPG loss. The terrible MPG is the result of brick shaped land yacht JK body and 4x4 driveline. Put the JK engine and transmission in a Corvette and you will see over 30 mpg.

Not worth it if you are considering trading in your used JK and take a kicking with the upgrades and mods a person added
IMHO it would be worth taking that money you lose on trade-in and look at a RIPP Supercharger addition! Get an extra 100HP out of the 3.8L and modified tunes and to boot probably better fuel economy then the 3.6L pentastar.

True...with a RIPP you could do better...that is, until RIPP releases their kit for the 2012. They already have one in development.
BUT LIKE A LOLIPOP IN THE WELFARE OFFICE IT COULDNT LAST ! 2012 CHANGE WAS ONLY TO EXTRACT MONEY FROM YOUR WALLET FRIENDS ! HORSEPOWER = $ AND FOR THE MONEY INCREASE YOU COULD DO BETTER AFTERMARKET!
