Is there much difference on the highway im debating which to get...

I4 gets better gas mileage, cause it is a 4 banger. But dont get the 4 banger, the V6 doesnt get as good of gas mileage, but it has much more power.

lol, i get around 35-37mpg average easy at 70mph even in the rolling hills of eastern montana, and i get between 32-34 at 75mph and about 29-30 at 80mph and i have a 2008 GT with the 6 cyl........however my intake exhaust and 93 tune help with getting the better mileage too........

I get about 25 highway with my 3.9

LOL glad i dont have the 3.9 LOL..........i've only put about 350 miles on my new GXP but on the highway at 70mph it seemed to get an average of 30mph on the 3.6L lol and that is STOCK so hopefully doin the same mods to it will put its mileage real close to what my GT gets haha

Put it this way: even on the highway my primary focus ISN'T gas mileage

Plus the vert weighs about 300 lbs more so that doesn't help )

OK plus I'm not the lightest guy around either ))

i get 38-40mpg hwy going 70-75, and i get 32-34mpg city/hwy mix. i have the 2.4. its got decent power, enough to keep me satisfied till i get my Evo. i only bought it for the gas mileage and size anyways.

Wow. This is unbelievable! Something must be wrong with my car than. I seriously fill up every 2-3 days and I drive HWY all DAY. Seriously?! I don't even drive her hard neither. Plus all these mods were suppose to make it better. Im pissed...

I get 22mpg in my 2.4L I4 driving to work (~10 miles) of street lights, it really sucks, but I get 32mpg on my trips from Southern MD to Central NJ, and I drive it as hard as I can, because it makes the I4 a little more exciting, not much though.

I will be buying a V6 next time.
