KJs usually get better from what I've seen than KKs
Doesn't seem like any KK gets that good really
Now there are a few KJs that experience bad mileage but those are the ones I'd like to have ahold of for a couple of weeks and 50-60 bucks

There will always be variances in mpg. The KJ may be a little more aerodynamic, but it also has a lighter curb weight. KK well for 1 it's newer, I know that in 2010 Chrysler tuned it a little more especially without decel shut off. Anyway a week ago I was at 17mpg now down to 15.4.

When you get knee-deep in a situation, floor it.

OK so a new stock KJ was lighter
but I'd say mine is even past a KK in weight now

I could have sworn that the KK was designed to be more aerodynamic?
It might not look it, but I'm pretty sure that's the case.

Idk, probably pretty close, but whatever aerodynamic gains we get are killed by the added weight like Tom mentioned. Same power figures plus more weight means you have to work harder to move it.

Sometimes I wonder how much LESS aerodynamic our KK's are that have the skyslider and if it is heavier than one without it.

The KK's frame was beefed up a ton in order to incorporate the sky slider and still maintain safety. That being said, even if you don't have a sky slider you still get the beefed up frame. I would imagine that the difference between sky slider and non sky slider are negligible

Got ya. I don't like how the KK looks driving at fast speeds with the sky slider.
You can see it shift a bit. Saw it for the first time when they had to test drive mine last year.

I bought my '11 las April. Since then I've been using an app to calculate my mileage. April through December my mileage averaged 19.2. Jan 1 I started over again and my mileage is 14.5 after 2 fillups. Last year my average per tank was between 15.5 and 21.6 not including December, is "winter gas" really that bad?!?

I average between 17.0-17.8 a tank. I have gotten as good as 20.2 on a trip to Myrtle Beach and around 19.5 on the way to Pennsylvania just after I got my KK.

Winter gas does make a difference if you live in a cold weather area.I doubt they modify the gas in Florida.

Here in South Africa we are averaging a 34-38 degC tempature range during our summer days. I am getting around about 17.8 - 20L/100km which is around about 11.7 - 13.2mpg. for average town driving (80% town 20% highway). I have managed to average on a +/-700km trip down to the coast last year an average of 11.7 - 12.2L/100km (19.3 - 20.1mpg) and this was at an average speed of 120km/hr. (+/-74mph) so I cannot complain at all.

What I think really kills the mpg as any vehicle is constantly hard acceleration and braking. I keep at about 65mph on the highway seems to sat in the 16-17 range. A/C use also effects the mpg and the winter gas as well.
