Cool Me and my MPGs

Have my overland for about a month now and Im enjoying it. I never had a trip gauge before in my car that gauges mpgs so I figured I would try it out.

I have the V8 so I knew beforehand city driving wouldnt be that great on my MPGs. After 200 miles I noticed that Im only getting 8 MPG!! That was all city driving. Not too happy about that.

Over the weekend I went on a little road trip. Reset the MPG gauge and was hoping for the best. After 100 miles of hwy driving and reaching my destination, I looked at the gauge and it said 18.3! I was very excited about that (kind of sad to be excited about 18 On the way home I drove with the eco mode on and managed 22.3 MPGs! I drove around with the adaptive cruise control which was great.

Mileage is a little worse on brand new cars like that it should increase a little over the next few thousand miles. V8s are bad on city mileage that's just going to be how it is. But on highway you can get some decent mileage out of this jeep with the v8. with speeds around 65 and the ACC turned on the MDS will stay on a good bit of the time and you can get into the 24-25 mpg range in 100% highway driving, in the flats to rolling hills.
I usually average 17-18 mpg in mixed driving.

Re: Me and my MPGs

Speaking of mpg and MDS and stuff. What exactly do the different driving settings do does anyone have a link that explains each? So default is Eco mode on. If you turn Eco mode off what exactly changes? Will MDS still activate or is that disabled with Eco off? When driving I notice slightly higher shift points. With sport on it obviously goes much higher and even throttle response feels different to me.

As far as fuel econom I'm on my third tank of gas on my new '14 Summit V8. 290 miles into the tank the evic shows an average of 17.4mpg all suburban driving (no highway, but also not harsh city). Mpg had been consistently going up each tank so far and I also log all my fillups with my fuely app. As of now the evic seems to be between .5-1mpg generous from what it's actually getting.

I believe its Multi Displacement System which is Chrysler's name for the cylinder deactivation.

Oh ok. I could never figure out if that was activated or not during my trip.

That means it's operating correctly...it should be unnoticeable.

Re: Me and my MPGs

I am very happy with the gas mileage on our new Jeep, V8 Overland. First 1300 miles are avg about 21 mpg, that is wifes commute about 70% highway. Got about 23 mpg on a trip.

anything over 20mpg in a 5000 lb SUV is good.

Eco mode is explained in the owner's manual:


When the Fuel Economy (ECO) Mode is engaged, the vehicle control systems will change the following:
The transmission will upshift sooner and downshift later.
The torque converter clutch may engage at lower engine speeds and remain on longer.
The engine idle speed will be lower.
The overall driving performance will be more
conservative.
Some ECO mode functions may be temporarily inhib- ited based on temperature and other factors.

I agree. Anything near 20 MPG in a V8 powered 5000+ lbs SUV is good!

They recently raised the interstate speed limit in South Dakota to 80, and my wife and I typically drive 5% or so above the limit. Doing 84 MPH on a 275 mile trip (one way) and back this past weekend, I wasn't expecting good MPG results.

I also didn't care a whole terrible lot, we bought a V8 powered SUV. If we had wanted gas mileage, we wouldn't have picked the V8 or a Jeep.

However, we got just a hair under 19 MPG on the way out there, and 20.5 MPG on the way back. I was pleasantly surprised.

Re: Me and my MPGs

Usually, I got about 12MPG in City and 18MPG on highway. However, It seems like I got better milage in big city. I think it could be something with the gas since I can only get up to 91 octane here compare to 93 octane in big city. I can get up to 20.8 to 22.5 MPG on the 93 octane gas.

Re: Me and my MPGs

I forgot to mention, the gas we get has the 10% ethanol in it and that clobbers the mileage.

BTW, we have been using 87 octane.

anyone done a few fills with 87 vs 89 to see if there is any difference?
