Is something wrong or does this engine just suck gas like a commercial jet? I was hoping for at least 15 or 16MPG.
Am I reading your post right? You only got 12.5 on your first 60 miles. Get some miles on it. The PCM is pre set at the factory to a "default". It takes at least 50 cycles to reset to your driving style. (a cycle is start - drive and get to normal operating temp - shut off) or maybe 500 miles. Not sure about that and do not want to mis-lead you.
Your KK is NOT a car, it is a JEEP.
You are in LA and driving in the parking lot freeways there. I have driven there and the freeway is a big parking lot........ I hate traffic so I moved to a town that has 1,833 people in it. Still 1,800 to many. But at least my driving is almost all highway and no stop and go.
The things that affect gas mileage the most are:
1) driver (the biggest thing)
2) type of driving (traffic/or highway driving)
4)vehicle condition (yours is new so no problem there)
5)tire pressure if it is too low(check yours even if the KK is new)
And a bunch of other things.
What does your window sticker say for mileage.? I am curious.
Remember, it's a Jeep, not an econobox or a sports car. It will take you places (and back too) that those other cars won't.
