17-18 highway, 14-15 stop and go. I have a bit of a heavy foot.
The best I can get is 18 mpg if I cruise the speed limit. For daily driving I average about 14 mpg.... but my truck is not a fuel efficient combo.
5.7L hemi, 6 speed and 3.92. It's a sport thru and thru.
Average for me is 19.1 with mostly highway. Haven't tried resetting and checking before a long highway trip, but I would guess somewhere around 21.
2017 5.7 with 3.21
2011 ram 5.7, 3.55s, 4x4 crew cab, with after market wheels, Cooper AT3s and Diablo tuner run 91 tune. 145k on clock
I get 18.6 on avg running real gas at 80 mph.
If I run corn gas it drops to 16.5.
Both trucks 3.21 gear ratio. My 17 and 19 trucks are literally apples to apples. Grill is different but don't think aerodynamically there is much difference. Could the vent visors possibly cause any noticeable MPG loss?
What are you guys finding as a sweet spot for MPG while on the highway? My 17' was 73 MPG. The 19' I have not yet figured out.
I was in the exact same spot with my 17'.
Doesn't the Warlock have a 1" lift from the factory compared to other 1500s? I mean, it doesn't account for the entire difference in mileage you're seeing but I'd expect it to be a little worse just from that.
My '15 (6 speed though) does about 20mpg on the highway in perfect no wind conditions on flat ground with MDS off. I have 3.55 gears and heavier LT tires than stock but that's it. My fuel economy seemed to peak at about 75,000km on the odometer (my average at that mileage was around 22mpg), then dropped a little bit and has remained constant. I'm now at 260,000km.
I have a 50 mile commute to work and I consistently get 19-20mpg. Not too shabby for a nearly 3 ton truck with a V8. Now city miles...that's a whole different story ha
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).
