Re: POST 2014 V8 MPG's

I get under 12 MPG (actually calculations, not EVIC) which is mostly if not all city driving. Mine is a V8 4x4. About what I got on my many other GC 4x4 V8's so nothing knew.

Re: POST 2014 V8 MPG's

I just checked the EVIC and was surprised to see 16.9 on the economy screen. Pretty good!

I've never reset it since I got the Jeep, but I've read here that it only figures more recent driving. I check my mileage every 6 months or so when this thread resurfaces.

I've never checked it manually, because I didn't buy a HEMI for good mileage. Plus, I won't drive any differently no matter what it is.

Re: POST 2014 V8 MPG's

We bought ours slightly used, so it was already somewhat broken in. In the winter, 15-16 MPG with about 70%-60% city. In the summer, that number is 16-17.

Last few road trips, it has really impressed me. Doing 80 MPH with A/C on, it gets 18-19 MPG if I use 10% ethanol laced gas, and 20-22 MPG if I use ethanol free. All hand calculated here. The EVIC is almost always 1 to 2 MPG higher than the actual, although I have to admit that this last fill up, it was dead-on down to the tenth of a MPG.

I have the instant MPG display on the upper right of my EVIC display and I keep an eye on it to monitor fuel consumption. I also coast to stoplights etc. I notice most people driving around me are in a hurry to get to the next red light. It's funny. I also try not to use the brake unless I have to. Slowing down for no reason is wasting gas, as you have to accelerate again. Again, I see people around me hitting their brakes when going down a slight incline, even going the speed limit, and with no one around them. Leave your brake pedal alone!! lol

Considering all this, I might have been happy with the V6. But driving thru the mountains and being able to pass 3-5 cars without thinking about it on a two lane road are some of the reasons I got the V8. Plus it's very smooth and moves the Jeep effortlessly. In my book, I'd rather have PLENTY of power when I want it, rather than regretting not having enough power. If I have to pay a 1-2 MPG penalty for that power, so be it. It's worth it to me.

I had a 2004 Toyota Tacoma crew cab with the V6. It got 17-18 mpg on a similar commute, except it was about 7 miles longer freeway driving. It was as gutless as can be on the freeway. It would downshift out of overdrive on the most insignificant incline, or a 5 mph headwind. I got rid of it after less than one year.

I tried using ethanol-free fuel for a bit. I got about 30-40 miles more per tank using it. Ethanol-free fuel seems to be catching on a bit around where I live, and the gas station has jacked up the price accordingly. Now it's not cost effective at $.42/gallon more than 10% ethanol 87 octane, so I'm back using the junk gas lol.

Here's a pic, going 65 MPH on a flat Oregon freeway. Almost 25 MPG, for a 5000 lb ride with 360 HP. I can't complain:


Agree highway mileage has been good and better than I expected with the V8 4x4. cruise control at 65 on fairly flat highway allows the MDS to stay on a good bit of the time so you are only burning gas on 4 cylinders. I have got similar mileage on highway trips as you. my local mixed mileage is about in the 17-18 range.
I bought the V8 because I wanted it I didn't even consider the other engines, the great highway cruising mileage is just an unexpected plus. Also have found the EVIC on this car to be very accurate compared to other cars I have had, typically been within a half mpg which I consider pretty good. I run regular also, if I towed or was doing a lot of extreme mountain climbing would go with the mid grade. V8 with the 8 spd very nice smooth powertrain, no complaints. march 2013 build here so had some software glitches early on unrelated to powertrain but all worked out now and all good.

Re: POST 2014 V8 MPG's

Thanks for the new responses. Doesn't sound much worse than my v6 escape 4x4 in city or hwy. Mind you I'd be doing pretty short city trips most of the time.

What about for towing? Anyone towing 1000-2000lbs with the 4x4 hemi? Wondering if a fairly light load like that on the jeep affects the v8 mpg alot?

I tow a 5x8 utility trailer when I go camping. It's probably about 1500 pounds (my wife CANNOT travel light lol). I usually get about 18 MPG, just a small drop.

Another small point...with the V8 it doesn't seem to make any difference in the mileage whether or not I fun the A/C.

I average between 25-26MPG (EVIC) Mixed 50-50.

I come close to hitting 30 MPG Highway only, flat 65 MPH ideal conditions.

The V6 is a beast when you step on it.

I've never seen below 20MPG.

Re: POST 2014 V8 MPG's

I am at about 1,200 miles now and I am getting about 15-16 mpg and I have a very heavy foot. When I first got it I was averaging 8 to 9 miles per gallon and was getting nervous something was wrong with it, but it got better with age

Re: POST 2014 V8 MPG's

I've settled in about 18.1 which is mostly 45 mph or less mixed, with weekend mountains with about 24K miles. Occasional "whee" moments, no real effort to turn MDS on. Solid highway driving is much better in the 22 range unless further west where it is flat and the limits are higher. Both are measured, not EVIC.

Hard core city driving in the bicycle speed range I wouldn't want to bet would be 18, as I do try to get up to speed quick rather than letting the engine run in the lower gears very long. Towing, you'd also expect to lose mileage unless light aero trailer on mostly flats.

Although the CRD is quite good for towing, if you do plan to tow across western mountain ranges such as on I-70 in Colorado and Utah, they seem to struggle to maintain speeds on hills where the Hemi is just relaxing.

2014 limited v8 4x4 ora II .. My evic shows 19.6 avg right now (its been dropping and usually settles around 19.1) and thats at 50/50 city/hwy .. on flat freeways with cruise at 75 I see 24-25. Drop to 60-65 and my evic bounces between 28-32 so more than happy with my hemi... if I learned to keep my foot out of it at lights and take off like every one else it would b better
