3.0L EcoDiesel Indicated Fuel Range

[dperez]

Hi, not sure if this is the right place for this question but here goes… I have a 2023 EcoDiesel with under 3,000 miles. Most of the miles have been city miles as I haven’t taken the Jeep on any long trips yet. Anyhow, I’ve been using mostly Propel HPR fuel, and the most I see on the gauge for range has been around 340 miles. I’ve heard stories of 500 mile range so I’m wondering where‘s that range? Running a rooftop tent and 315/70/17s but even when I was running stock I wasn’t getting much more.

Range to empty varies widely. It's based on how you've been driving lately. After a lot of in town driving you'll see less range. If you do a road trip with mostly highway miles at or under 70 MPH it will go up.

The tent will probably be a big limiting factor though. It'll knock several MPG off the top end and that will hold your range to empty down.

The stories I’d seen of really impressive miles / mpg were a while ago and from the 2020 model year. If I remember correctly, early to mid 2021 a software update was for forced on everyone to “improve emissions”. It reduced mileage and increased DEF consumption.

I got mine in September 2021 and it already had that update. I think I’ve seen close to 400 mile range on straight road trips but mixed driving has been closer to 300-350.

I agree with @grimmjeeper higher speeds really impact mileage and a RTT makes things worse.

500 Miles you're not going to be getting from City driving. I did that once, 34.86 MPGs, 55 mph was the fastest I drove, 90% highways.

I do probably good 80 to 90% highway driving most days of the week, and I average 23 to 24 MPGs. And that's with all of my weight reduction things I've done. I also like the skinny pedal, so I'm usually going 80 to 90 a lot of times, and I'm still getting 23 to 24 MPGs, so that says something.

You need to get on the highway more often, you're going to kill your EcoDiesel doing City driving. These things live for long distance drives. If you're not at least hitting 70 mph for 30+ miles once a week, your vehicle is going to be doing a lot of regens in your driveway.

Be aware too that the MPGs the dash is giving you on average will be about 1 to 2 MPGs higher than what you're actually getting if you were to measure it at the pump.

The formula for aerodynamic drag is:

.5 * p * V^2 * Cd * A

That's

.5 * air density * velocity^2 * drag coefficient * frontal area

Velocity is squared, so MPGs drop dramatically as speed increases. Avoid interstates if decent numbers are your goal.

Note that it's a Wrangler, not a Prius. If fuel efficiency is required then you might have the wrong vehicle.

p.s. take @Tredsdert's numbers based on his "weight reduction" comment and understand that he's in Texas where they don't give a damn about stuff like that.

My experience with an iKamper is about 1 mpg loss. Highway use in the 70-75 mph area runs about 21-23.5 (actual not EVIC) but I run pretty heavy with a lot of gear.

Realistically speaking, that ~35 MPGs was done with the factory tune and factory tires. I feel like whenever I do my next MPG run with my stage 1 tune, my numbers will be a lot lower. The stage one makes it a lot more fun to drive, but I don't think it is doing anything for my fuel efficiency. If anything I think that adding 35s will actually improve my fuel efficiency over what I will have lost with the stage one tune..

It's probably one of the few cases we're adding bigger tires actually improves your mileage.

If you were to hypermile it, on flat highway, at lowish speeds, you might get there. But, no one drives like that except the marketing department trying to get good copy for ads.

Have you met @Tredsdert?

You're thinking that a bigger / heavier tire improves fuel mileage? That seems questionable.

I had screwed up that tank, so I ended up filling back up to a full tank super early and for the last 4 days I've been running with a max speed of 55 mph, and I've noticed that cruise control increases my speed super efficiently without that heavy pull you get when you press the gas pedal slightly with the EcoDiesel. So I've been running pretty much anything over 20 mph on cruise control. I have a 20 mi drive to work everyday, I'll be in the slow lane going 55 with traffic passing me like crazy on our 70 mph Highway 75. I do the same thing in the afternoon with the whole lot more traffic on the highway, 55 mph on cruise control in the slow lane.

FINAL TALLY: 33.45MPG

Hypermiling at its finest!

That's my best MPGs to date with a full tank.

I did a half a tank once and got a little bit higher, but I got a lot of gripe about not completing the whole tank so I don't really count that one.

The only way you’ll get a 500 mile range in your Jeep is if they put in a 25 gallon tank.

I was being facetious, that’s pretty good mileage but is that your normal day to day . The best I get is between 25-26, a little better on the interstate, but who goes 55 on an interstate.

Well, it has been a few years, but in 2019, the Wife and I spent a week in TX, Austin, San Antonio, Corpus Christi, DFW. We saw a lot of TX, but certainly not all, I will say that the Women take “Weight Reduction “ more seriously in TX, than the women in the PNW do.

Oh we have some Beauties in the PNW, but the percentage of HWP people, women in particular, were higher in TX
