Highway Mileage What Are You Getting

[Pezrock]

Winter fuel can change things a lot so be sure we're all comparing apples to apples.

"Break-in" of a vehicle is one of the more laughable MPG subjects on the net - what exactly is getting "broken in?" Are there little squirrels in the engine that need to get in shape?

73MPH is not a MPG "sweet spot" for any vehicle. There's a reason 55MPH was set as the national max around 1980 - to save fuel. Other experiences are either conformation bias or had other factors that weren't taken into account (most likely a tailwind and/or driving downhill).

Not sure about a break in, but I have heard and read about it since I was a teen. If there is no such thing than fine. Thanks for clearing that up.
I noticed that my MPG is about the same at my normal driving speed of 65 to 73. As soon as I start to head north of 73 the MPG seemed to suffer at a much higher rate. Again this was my 17' that I no longer own. With that said, I simply want to know why my 19' is not even close. I can't even get it close while babying it.

Damn, I am lucky to get 14-15mpg on highway and 11-12mpg city.

 

[JayLeonard]

I can get over 20 on the highway. Around town with all the traffic lights and idle time I can just break 16.

20 to 22 on highway

I was given a 19 classic warlock for a loaner while my 18 Lonestar 4x4 lifted ram was in the shop. I average about 17 most days and push 20 on long highway trips.

The warlock I was loaned was stock height same 5.7L but 2wd and that rebel looking front bumper and grill. I averaged 14-15 with it. The only thing I can think is the under the vehicle draft. The warlock doesn't have the air dam/director under the front bumper. When I installed my grill guard on my 18 I left it off and dropped almost 3mpgs. I put it back and whammo it was back up.

I think the front bumper areodynamic make a bigger difference than you think.

2019 Classic Warlock v6 4x4. Did a fillip and headed out. Trip was 70% highway and all I got was 18.8 using cruise

My overall avg is 17.9 maybe 50-60% highway

Hi guys....new to the forum...and 1st post

I have a 2019 Warlock, 5.7, quad cab. My daily commute is 120 miles round trip, almost all highway miles

Averaging 20mpg with MDS off at average speed of about 72 mph.

BTW....my F150 2.7L EcoBoost was averaging about 19mpg...

I LOVE THIS TRUCK!

2019 classic CC bighorn with stock tires I get between 19-21 on highway and between 13-14 in city usually (closer to 13 most of the time).

 

[boblonben]

On long highway trips, with my MDS System disabled, i get roughly 19-20

with mds you'd get closer to 21, mine does all the time.

 

[boblonben]

My 2017 Crew cab with 3.92, 5.7L and MDS ON. In town average 18 +/- .5, on highway (few hills) I average 22, again +/- .5. on 87 octane fuel. With no alcohol fuel my mileage jumps up about 2 mpg in both venues. Don't tow but very little, and don't carry much at any time, except people usually three. Tires make a difference also. I have BFG Rugged Terrain stock size tires, lost about .5 mpg when I went to them, but they are worth it. The previous were General HTs highway tire, they were good on road but not much off, even gravel. Anyway. My son's 2019 gets the same as mine.

my 2018 big horn with 15000 miles going to Florida from new york, i got 21.7

Straight highway so far I get around 22 as measured by the computer, with the cruise set at the speed limit on flat ground.

My record trip was 28mpg, but this was on a 35mph surface street later at night with minimal traffic and looking way ahead to coast towards any light and never use the brakes.

Most of my driving is "city" though and I get between 15 and 19. The definition of city can vary though, like if I run on a short trip to the store where there's lots of stop signs and traffic lights, that's the 15. Taking my daughter to school where more than half the drive is 35-45mph roads with no stops I can get 19.5 if I'm careful.

I like NJMOPAR's answer about Smileage ! I got a call from Thousand Oaks Dodge several years back and he wanted me to buy a new crate Hemi he had in stock. I told him I didn't need another but I was amazed at the effect the Hemi had at car shows ('67 Belvedere Convert ) and he laughed, said it's the WOW! factor. That's just what people say when they see it !
People ask me about mileage and I tell them, Not much! Had'er for almost 23 yrs now.
Drive safe now, ya hear ?

My 2017 Ram 5.7 quad cab all stock I averaged 19.5 to 21.0 when I had 20K on her. I now have a 2019 Classic Warlock quad cab all stock and same tires and tire pressure as the last Ram. I am now averaging 15.7 to 17.0 for the same 2 hour trips I make every weekend. The only difference is the truck only has 1200 miles on it and I installed in channel vent visors. I expected a lower average during break in period but not 3 miles less per gallon. These trucks are almost identical except for the vent visors. I am not driving at high elevations either. Thoughts and experiences?

I get 22-24 with the same truck, I also have 3.21 gears... I get about 17.3 around town. CAI and Borla muffler.

 

[Jerrybob]

I've got the 3.92, 4x4 with tow package.....I get about the same....21-22 on highway with cruise set at speed limit.....17-18 if in town. I also get 99mpg going down big hills.....LOL!

2013 ram 2500 diesel automatic Hauling 10,000 lb toy hauler 8mpg, 16-17 normal driving to town, 19 highway

 

[bigred90gt]

2017 Crew Cab Hemi 3.92 gears with 285/60/20 Nitto Ridge Grapplers (slightly larger and a bit heavier than stock). I average 16.5 combined (probably 60-65% highway). Last time I took a road trip I think I averaged right at 18 highway on the 4.5 hour drive, but around here out in the open stretches the speed limit is 75. I’ve never driven more than an hour at 65 on cruise control because there just isn’t any direction I can drive for an hour and still be limited to 65.

I’ve never driven enough just “city driving” to get an accurate assessment of city mileage.

My 2014 1500 3.6 is a lot smaller than yours but I ride as much on Cruise and never over 70 mph so, my mileage is terrific---nearly constant on the highway of 27. Combined about 22-24. I don't drive exclusively in town so I have no feel for that.
But my 1500 I'm still thrilled with it for nearly 6 years and have no thoughts of changing to bigger or different. Dodge has done me good (mostly). But this is rural Harrisonburg, Va. where us dislocated Yankees feel at home. Antie Em, you ain't in Connecticut any more!!

Excellent point , I'm sure most people don't know that all the mpg testing of cars and trucks by the manufacturer to satisfy the government mileage mandates is done at 60 mph. This is the speed that they use as a standard to come up with the fuel mpg ratings. On the other hand I don't want to ever go back to 55 or even 60 mph. On the interstate highway it always made want to open the door and step out to see why I wasn't going anywhere Lol. I'm a 75 to 80 mph guy.

This winter I've been seeing 17-19 on my '15 Crew, with snow tires, auto4wd engaged.
