Bad fuel mileage 5.7 hemi

[Zeronet]

Any members in Rebels getting anywhere near 15 (or better)?

Some older threads on Rebel mpg.

2019 rebel gas mileage with e-torque

I’m getting around 14mpg with a 23gal tank. 5.7, 3.92, e-torque. Is this about normal? Old truck was 2014, 5.7, 3.93 and got 19mpg with 26gal.

Rebel Gas Mileage vs Every Other Trim

I believe the following information from the Fuelly Website gives us a pretty good idea how Rebel vs Other Ram 1500 owners drive :) Big Horn: Avg MPG of 15.06 Rebel: Avg MPG of 8.86 Laramie: Avg MPG of 14.52 Laramie Longhorn: Avg MPG of 11.29 Limited: Avg MPG of 13.56 (Only 2019 models with...

I've read the thread and following new posts - but haven't paid attention to the model/trim each user has... Any members in Rebels getting anywhere near 15 (or better)?

I'm still seeing low 13s on the gauge (which means hight 12s in practical calculation).

15-16 at 75 on flat ground. Been getting slightly higher lately. Took a 2 hour trip north of me, 16 there, 19 back.

I figured many of the decent number reports had to be Rebels... Mine seems to be an anomaly - I get nowhere near that


I have just under 1200 miles - and there's no way this thing will see 3-4 mpg better after more "break-in".

There a lot to like about this truck - but I'm getting the lowest mpg of any I've read about.

I'm only get around 16mpg, 30miles from home to work and 2/3 of it is highway.

I know it's petty but I absolutely floor it when around Prius cars....I get that people with long commutes and limited budgets need it but they are so fugly.

Ha ha, I had a Prius for 5 years... Another one of my "can't get out of its own way" cars. The gas mileage was stellar (lifetime over 100K miles driven was 53), comfort/ride quality, performance were dismal. I will say that it was by far the absolute most reliable and least mechanically needy of any vehicle I have ever owned. Other than the recommended maintenance that was performed (which in hindsight I could have totally skipped), in 120K it cost me "0" in breakdowns or unnecessary dealer visits. I was sad to see that part of it go.
It has saved a lot of fuel to be used by Rebel and Raptor owners though...

What are you guys talking about??? I thought everyone got 20 mpg with their Hemi (80% highway mix)

Fear not. Im at 5500mi this week and its been interesting to watch mileage improve over time. I bumped my tire pressure to 45psi from stock 36-35psi. Im also about 800mi into fresh synthetic with a Lubeguard moly additive after the factory oil was dumped and mileage has become tolerable.

I bet you could have done better in 2WD.

I've been thinking about changing oil/filter and air filter to see if it helps (only at 1200+ miles though)...

door jam states 55psi and they've stayed consistently close to that - nitrogen filled so I don't want to mess with adjustments if I can avoid it. *side note: I know most people claim nitro filled is a gimmick (and maybe it is) - but the psi doesn't fluctuate as much with these tires as they have with other trucks I've had.

Hopefully the MPG will get better, as you and others have advised. I'm a little less than optimistic that it will ever be as high as most that I'm reading here.

My wife has a Prius as she has a long commute to work. It's our second one and she loves it. I can't stand riding/driving it, as it's noisy and uncomfortable. It is, however, dead reliable and cheap to own. 126K miles and I have only done (myself) oil changes and tires. Cheap to own for sure, but we take the Ram on trips for the comfort.

We try to the same thing, truck is best on trips when I can get her to use it...

I’ve previously stated I’m not one to worry about MPG but after reading all the comments I’ve been looking at it just out of curiosity. My normal work commute is about 3 miles round trip and I was averaging about 10.3 MPG. I recently had hernia surgery and had to make several trips of around 80 miles round trip and my MPG went up to 17.9 MPG which I thought was a pretty good improvement. This was averaging 60-70 MPH and running 93 octane with MDS deactivated on pretty flat roads and I do tend to drive aggressively. Anyhow just thought it was interesting how much my MPG improved but again I don’t really care, just thought I’d share my experience.

 

[Willwork4truck]

Sounds about right. Only my Prius did well on a 3 mile drive lol...

A cold engine will run rich, and just about the time it's warming up...you've arrived and shut it off.

Give it some time. It will get better with some more miles on it.

I reset it before going in to work yesterday. Heavy rain (4auto), did not exceed 60mph on the way in or back...

Mine has been pretty decent commuting but above 70 it’s not great 14-15 MPG, my mixed driving 30 mile commute is usually never over 70 due to traffic and I get 18-20 but my road trip doing 75 for 150 miles it dropped to that 14-15 range which was a bummer because I figured my straight HWY would be better than mixed but I guess that ECO below 60 is making a big difference setting at 2500 miles on my 20

I'm about the same as you. I assumed I would get better MPG on the highway, but speeds above 70 bring my mileage down. Commuting and around town are at 55 mph or less for me and I see the ECO light quite often. I very rarely see the ECO light when on the turnpike at speeds above 70.
