I've had those readings stick for almost a 60 mile stretch, at that speed on cruise control. I don't get to drive that fast unless I'm visiting my in-laws and we're on the collectors highway. BTW, 5l/100kms works out to about 47 US MPG, that ain't bad for a tank on wheels

Thanks
Actually that is very good news in that 9th is actually used at around 84 mph in a sustained manner. So it is designed to work and does work.
Now all FCA has to do is figure out how to get it working earlier so as to avoid that mpg drop at 70 mpg plus.
That was very useful information.

Dont top up past the auto shutoff, you could damage the emissions system.
Agree...all of my fill ups for the first 5k miles have been in that range too. I get between 26-28 mpg (3.2, AD1) and can normally get 350 miles out of a tank. My driving mix is about 80% highway, 20% city. I do leave ESS enabled as my mileage drops quite a bit for the city part of the driving without that fuel saving feature. Don't really like ESS, but it does its job.

The one thing I hate about my 2017 Cherokee Trailhawk is the size of the gas tank. 15.8 is just not big enough. I hate having to get gas every week.

I used to drive a Grand Cherokee with 24 gallon capacity.

IMO the Cherokee should have at least 18-20.

I don't get the whole " stop on the first click" thing.
A lot of the time, the first click at the pump is premature. Like half or 3/4 full. I hate leaving the gas station and realizing that the tank isn't full.
I started waiting 30 seconds from the first click and going to the second click. It usually dispenses 0.1-0.2 gal more, but sometimes it's a gallon or two.
So far I haven't overfilled to the point of fuel coming out of the tank.

You obviously haven't read the few horror stories on this forum, about overfilling. I hope you never experience the consequences. The KL is sensitive to overfilling while many other vehicules are not. If you choose to generalize and top off your Cherokee because you assume it's Ok from the other vehicules you've owned, and because you feel that the gas tank is too small... well... be warned...

For what it is worth, my range reading fight after a fill up has always been at around 300 miles. If I've done a lot of city driving, it drops down a few, like 295. But for the most part, its always stayed at around 300.
