Horrific Gas Mileage Hemi eTorque

[OldSkull]

I just had all the updates yesterday and I’m really hoping mine improves to at least 16-17 MPGs.
I have 2000 miles on it and Currently averaging between 9-12 MPG. If gas MPGs don’t improve across the board for these trucks their should be a buy back. I love the truck but getting 10 MPG less than the sticker advertises is total Bull Sh!t.

I don't have e-torque(regretting that now, and trading in is a 10K loss), but have been consistently getting 11.5-12mpg. Brought it back to the dealer twice now and the first time they applied some updates that briefly helped but then it slowly but surely dragged back down to < 12. Though I'm not really sure what normal "city" driving characteristics should be. I live in a fairly dense city(Portland OR), and driving for me is lots of 25-35 mph, with plenty of stop signs/lights along the way. Though still from my perspective, that's "city" driving, and I'm getting much lower than what was advertised. And often when I'm driving on the highway the mileage just stays pinned to where it was, or even sometimes degrades more. I do like to punch it on occasion but I've been driving it with a pretty light foot as well, and the eco light comes on about 50% of the time.

I just hit 1K mileage, but this seems really bad even for the break in period. Wondering if anyone else is getting this level of bad mileage with "city" driving? Really tempted to push hard for a return at this point.

I’m in the same boat. I’m getting 9-12 MPGs with almost 2000 miles on it.

Just another data point update on mid-July build, eTourqe. Up to just over 2k miles. Total MPG since purchase is 17.5 with a total miles driven est. of 60/40 (City/HWY). Last 2 tanks were 18.25mpg and 18mpg, both on 89. Holiday road trip about 150 miles, rolling, not that windy...a lot of adaptive cruising at 70 +/- 2mph. Filled up with ~100 miles to go on 87, ended with 20.3mpg. Family and bed full of Christmas stuff...so maybe momentum helped on the downhills. With 9-12mpg average, something is really wrong or maybe a real bad case of twitchy on/off throttle foot...My better half has this (nauseating as a passenger) and I've noticed in all our cars, that her mpg's are always dragging things down.

Hang in there. A couple of you have extreme cases like this. These numbers are 100% absolutely abnormal and cannot be accounted for by the variables affecting fuel economy... unless you were towing 5,000 lbs the whole time.

eTorque builds are reportedly on hold and the reason why is unknown. It might be a parts supply issue, it might be because FCA wants to clear out the 2018 leftovers, or, and this is a big or, maybe it's on hold because engineering is investigating.

If we don't see another TSB in the Jan to Feb time frame, I might start losing hope, but for now, let's wait and see if FCA can get this ship righted.

I hope you’re right. Is this poor gas mileage only affection the E-Torque Rams?
When I took it to the dealer yesterday the Tech asked me what was going on, when I told him how bad the MPGs are he said there was No Way I was getting 9-12 MPG, I waited while he took it for a cruise. When he got back he said “something isn’t right” LOL... I’m going to try and put another few hundred miles on it this weekend to see if the updates helped.
I’m Really Really regretting getting the E-Torque.

I tip my hat to you, Sir. The only way to fix this will be from people like you who have demonstrated this problem to the dealership. Nowadays, dealership technicians are connected to the cloud. When they document a problem, they do so on terminals that are linked to engineering, management, and whoever else. Point being is that customer reported problems get instant visibility to those who need to know throughout FCA.

I hope everyone who has fuel economy issues will do the same. The more documented cases, the greater weight it'll carry.

My personal (speculative) opinion is this is a software issue. If software isn't right, it seems theoretically possible that the engine is not being properly "released" and maybe in regenerative braking mode for longer than it should.

Quite a few others have reported their eTorque works exactly as intended. I think once this happens for you, you'll no longer regret it. I say don't sweat it for now; just enjoy the other really nice things about this truck.

I don't have e-torque.
I'm getting 12-13mpg city and highway like 15mpg highway.. it's bad but I knew the cosenquences when I got the truck

The non-eTorque Hemi in a stock truck should do a little better than this. I have the non-eTorque Hemi in my stock 2018 AWD Durango Citadel and can get up to 15-16 mpg city and as high as 22-23 mpg hwy. It is rated at 14/22.

With your 3.5" lift, 22" rims, and 35" tires ... i.e. NOT a stock truck... your poor-ish fuel economy seems normal to me.

EDIT: My Durango has 3.09 rear gears.

Not sure if the eTorques are on hold anymore. I have a truck on order with the eTorque engine. Does not mean issues are fixed with motor though. Currently in G status waiting to be assembled. Sterling Heights Plant in shutdown until Jan 14. Even when assembled, it may not ship if they decide not to certify it. Who knows

I'm getting the updates on Monday. Luckily I'm hovering around 15 so it's not as bad as some. I'll update afterwards (2019 Bighorn, 5.7 eTorque, 3.92 rear axle)

Good luck. I look forward to your report

Lots of stop-and-go traffic and higher speeds (60+) with the 3.92 ratio are not going to see anything close to those EPA numbers. I'm really not sure why all trims with all ratios are given the same EPA numbers.

I got the 3 updates and I'm still getting 16-17 around town, 15-16 at 70+ interstate, and 19-20 at 55. I have a Limited 4x4 eTorque 3.92 with ORP. 88 octane from MurryUSA (Walmart). My mpg seems slightly better with Tier 1 89 from Shell.

I have a similar truck (no etorque) and my numbers are marginally better...I follow the manual which recommends 89 and Top Tier for best performance....

 

[slimchance]

almost 1,400 miles on MY truck (see sig. below) .. 280 miles local driving and took a short trip yesterday of 150 miles, 4 lane and 55 - 65 speed limit ... before trip dash was showing 17.7, after trip and fill up calculated to 19 mpg , dash showing 18.9 ... i am very happy with this setup on MY truck

I would be. I’m at about same mileage, never been over 15.6. I drive conservative. Mostly 60mph highway and a little town driving.

People don’t realize this; top tier gas is a noticeable difference against others. Most stations who do not use top tier certified fuel go to the lowest bidder. Hence cheaper prices.

Top tier stations are always my go to, if not, ethanol free fuel.

I do not know the source of your information, but it is statistically incorrect. Fuel starts at the wholesale level as pure regular unleaded fuel refined by different companies. In USA it is generally 10% ethanol 90% unleaded fuel. What make Mobil, Sunoco and others, their brand is the additive pack. So fuel is generally 99.5% unleaded fuel and .5% additive pack which the brand name specifies. All off brand stations have some kind if additive pack in them, just not the one franchised by the major brands. This info is readily available anywhere. This is not to say some particular brand may not work better in your vehicle. These are just the economics of making and delivering fuel. There general reason major brand fuel is more is franchise costs. Think of buying a shirt with a Nike logo and then a generic one. Same shirt, no logo equals cheaper.

The quality and quantity of the additives are key. Just 'cuz you're getting some, doesn't mean it's adequate. There's a reason that the vehicle manufacturers define what is Top Tier Gas.

I used to buy my gas at Sam's Club, due to price and convenience. Over time my vehicles started running like crap. I switched to Top Tier Gas, which can also be just as inexpensive, and no more performance issues.

Buy what makes you happy, but there is a difference.

I generally agree with this. There is one point however: E10 (basically unleaded gas) has up to 10% ethanol. The more ethanol, the worse mileage but also, the cheaper gas. I've never looked to see if the actual percentage of ethanol is listed anywhere but I believe, going to 10% is one way that off brands make gas cheaper.
