Poor gas mileage

[law]

I'm in Eastern Ontario and I can only think of a handful of hills haha! It makes southern ontario look mountainous(and warm) funny enough, my wifes dream is to live in a house on top of a hill so we always talk about moving just for that aspect! Temperatures were pretty close when I was doing my mileage testing as well, although todays its finally above 0 and with the white one that goes back tomorrow, I still only got 16mpg running 70mph/110kmh on this flat 25km highway run. I don't use remote start purely for the hemi tick reasons - I use the block heater overnight and it keeps the block close to 25C when its -25 which is great! much cheaper too haha.

The old truck had the stock 20" wheels with 275/60/20 BFG K02's. They're a bit heavier than stock but fortunately just D-loads. The new one had 33x12x5x22 Rockblades (it was my first time hearing that name despite working in a tire shop for years during university), and they are E-rated, so the truck getting the better mileage actually had the heavier tire/wheel set and 3.92's! Fortunately, it's at the dealer now getting the licensing switched over along with 305/45/22 Toyo ATIII's since a plastic junk mud tire is not functional for a Canadian winter!


The old one goes back today/tomorrow, just waiting for the call, and I'll report back with the new one (2022) in a couple weeks again after I've put some miles on it! Pretty pumped and optimistic though!

yeah those mpgs on the previous truck definitely seem like theyre on the lower side. from the few times that i decided to reset the mpg counter before getting on a highway i was averaging 18-21 mpg going between 115-125 kmph, and my highways are also as flat as can be; however i am running the standard 285/45R22s winter tires and all seasons.
agreed with the idling, i usually just let the rpms come down and keep it easy on the pedal until oils get up to temp. i've yet to plug in my block heater since the truck is garaged at home and has heated parking at work, though there have definitely been a few days i've felt like i should.
what's your method for plugging it in? i find the block heater cord to be far too short to the point where popping open the hood and leaving it up to plug it in is the only option

it's just long enough that it can dangle just past the fender liner and I can plug it in through the wheel well without popping the hood. I started by popping the hood but very impractical and time consuming. I really only plug it in if its -5C or below tbh, and still give it 30-60seconds to drop the idle before driving away.

Had a 300sqft single car attached garage quoted last spring but prices came in at 90k+ so, maybe the next house it'll get to stay in where its warm the silver lining to keeping it outside when its so cold is that apparently it corrodes less than going from cold to warm over and over.

interesting, i may have to give that a try in the future!

yeah the heated garage is definitely not doing any favors when it comes to corrosion, i've finally booked an appointment to get some honeyseal done when summer rolls around. luckily in alberta we don't have as big of a rust issue as ontario though

I've seen reports of others getting poor gas mileage in their 5th Generation Rams. Mine is horrible. Has anyone else gotten a dealer to figure out what's wrong with this truck?
I've had my truck in the shop twice now for this issue. The Ram technicians are not able to find anything wrong with the truck.

It is a 2019 ram 1500 limited 4x4 crew cab with eTorque engine. Fuel economy is supposed to be 17 city, 22 highway.
I have the active suspension, and every option imaginable. 12" touch screen (which I would not recommend after living with it).
I only get 12-13 mpg city and 15-16mpg highway.
I have the 3.92 rear axle with anti-spin diff.
Eco mode almost never turns on in this new truck.
I have no performance options other than what the truck came with.
I have 12,500 miles on it now.

My 2016 ram quad cab with 5.7 hemi 4x4 got 20mpg or better consistently on the highway thanks to the eco mode.
I should be getting at least within 1 to 2 mpg of what is stated. My 2016 truck promised 20mpg and I got better.
I drive conservatively. I drive mostly highway. I don't idle the truck.
I thought the eTorque would be the way to go. I would not recommend it.
I've owned 4 of these trucks, each one better than the last, until this latest one.

I was given a loaner 2019 Ram 1500 with the Hemi, crew cab, same as my truck, but no eTorque option. I towed a trailer with that loaner truck for 250 miles and averaged 19.5mpg in tow/haul mode. It was the same year as mine 4x4 with the crew cab and hemi, and it got much better gas mileage. The only difference is mine has the eTorque, and this loaner did not. I can't get gas mileage that good in my truck, when it's empty and riding steady at 65mph on the highway. When I tow, I get 12 on the highway.

Something is wrong with my truck that is not wrong with all of them. Has anyone else experienced this and have you gotten it properly fixed? I'm at the point where I'm fighting with my dealer and I need to tell him what it is. He has put the OBD tester on it and says it has no codes.

I have a 2019 North Edition with no e-torque just hemi and 392 gears when new I got 14-15 local and 17-18 hwy now @ 50k I'm getting 13 local and 16-17 hwy.... towing is horrid at 6-7.5

 

[kapinallinen2]

13 local and 16-17 hwy....

Sounds about right. My Hwy. drops down to 10 to 12 mpg with my air brake (rooftop tent) on the rack.

Update: only a couple weeks and a couple of tanks in with the new(er) truck but my to-date average is 14.8mpg 19L/100km, compared to 10.9mpg 25.9L/100km. Extremely satisfied now, especially running 3.92's with larger tires than the old one and getting a 4mpg improvement!

To put that in perspective, throughout my 15,000km of driving per year, it would work out to an annual fuel savings of $1,300CAD I'm saving 5$ per trip alone to bring my little guy out to his grandparents once a week (50km roundtrip)!

let's see that again after 3000 miles.....Without resetting the trip meter!

Exactly. My last tank was a 500 mile round trip averaging about 60 mph. I got 20.5 mpg with big tires and 87 octane. That’s HIGHLY unusual.

Reality is normal every day driving it’s mostly in the 14-16 mpg range for me.

Sorry it’s no 3000, but will 1818 due?

Except that trip mpg readout with that many miles is on never an accurate depiction of actual mpg. Seems like it takes from recent readings for whatever reason. It’s far from the real calculation over thousands of miles.

I left my Trip B without resetting since my truck was new and with 52000 miles it shows 18.5 mpg. I sure as heck know that’s not correct. Not sure why RAM can’t get that right.

 

[ferraiolo1]

When ever I do a trip I hand calculate it. The read out on the dash reads .5mpg high on average. Which is a pretty low margin of error.

That 1818 was with a truck full of luggage and a 500lb street bike in the bed from Pa to Tenn in the mountains.

It’s all about driving habits and not putting large aggressive tires on your truck.

It’s easy to get good mpg..

I skipped the part about driving habits and not running bigger tires.

 

[ferraiolo1]

Well yeah, common sense, don’t put large aggressive tires and be heavy footed and you will get good mpg.

When I put my 22s and 33s on it, I loose 3mpg instantly, and my speedo is about the same. But the tires and wheels are much heavier.

I love these highly subjective threads and the bickering that ensues because of them.

Popcorn at the ready.

I get 1 MPG. Just to offset the median because I'm all hopped up on Mt. Dew. Lets go.

so basically one trip doing an average of about 47mph, nice! Can't say I've done any of those yet, it's usually either city or highway (60-70mph)

This has been debunked here already for the most part. While driving habits and things like tire size do affect mpg, there is quite a drastic range between these trucks even when identically spec'd, so it is not all about habits and tires, much like fitness isn't about working out and not nutrition.. it's a combo of the two and both sides of the spectrum are worth analyzing.

If you consider the thousands of parts, manufactures by hundreds of companies, in untold countries that probably hate us, by less than inspired individuals having not so good days and sometimes bad attitudes, it really is a wonder that any number of vehicles have similar economy. In fact, it's a miracle that as many as do even make it to their first oil change.
There are really TOO many variables, including driving habits, to even consider any truck to truck comparisons.
There are good trucks and bad trucks, just a fact of life.

lol. So you missed this one of almost 2k miles, loaded down, in the mountains, getting almost the same mpg? So yeah. Keep stock ish tires on the truck and your right foot outa the pedal and you can get good mpg..

What? It's the same average just over a longer time and more miles

Debunked by who? Keep the RPM's under 2k and you'll get good mileage, it's all about driving style and not having big off road tires. I've hand calc'd every tank for the 1st 4 years and it never deviated by more than .3-.5 vs the trucks calc's.



Mixed City/Highway 70/30


Mixed City/Hwy again


Dallas to Houston


Mixed city driving



Mostly city driving

I average 400-430 miles a tank (using 23 gal) in mixed driving, every single tank. On a Dallas to Houston drive, when I've stayed under 73 MPH, I've gotten 23 mpg
