My Lifted MPG observation

[SilverSurfer15]

The dash stays around 12-12.5, hand cal is usually about 1 mpg less. This is for straight up city use, plus like an hour of idle time per tank because it’s always 100 degrees here. So basically worst case scenario mileage unless you drive inside a ‘real’ city and are stuck in brutal traffic.

On the highway it seems about 13 but that’s kind of a guess. It doesn’t really like to go 61-68 mph, just with the gearing and what not. So if you run it at 58-60 in the right lane, maybe as high as 16 if it’s flat but probably 14-15. It will run 70-75 better than I thought it would, once the rpm gets high enough in 8th to actually hold the gear. (Thats the issue with the 60mph area). Probably does 13-14 at 70 if it’s flat. If there’s rolling hills, forget about it lol. I wouldn’t want to drive it all the time in say PA on the highways where even a stock truck has to let it rip to keep up speed. It would be horrendous and suck to drive.

This truck around town in same scenarios would barely bust 13 stock And really never averaged more than 16 on the highway at any decent speed but I don’t drive enough on the highway to really care about the loss there.

What gears?

Doesn't sound too bad for a lifted full sized pick up. I just did a long distance trip and was ave 19.6 at 80 mph. But that is a 100% stock pick up. Around town the mpg drops off quite a bit, a good 4-5 mpg.

I'm getting the same <12 mpg on my stock Rebel with 3.92 diff. after 5,600 city driving miles.

I have been able to get 22mpg on longer highway trips and usually average 16 around the city.

All rebels are 3.92s from the factory.

Yea you’ll never seen that in a rebel. The factory 33” tires are aggressive tread and heavy. Stock, the best I ever did was 18 ish running 55-60mph for a couple hours in between Alabama and Florida. At 75 on the highway, 14-16 depending on the terrain. And that was down there, up north in the mountains I would assume another 1-2 hit.

Yea when I used to lived in DC I had a stock 2wd Crew can with 3.21 or whatever the tallest one is. It only got about 12 as well, granted that traffic was brutal. I just don’t think the hemi can do much better than that in the city situations. I switched to a 2.7EB ford here, and went up to about 17. Kind of crazy lol.

That's actually not as bad as I thought it would be.

The Hemi isn't kind to city driving, that is certain.

Ah, I didn't see where you mentioned it was Rebel.

If you haven’t updated your computer to recognize the larger diameter of 35’s your mpg average, odometer & speedometer are wrong by ~6%.

When I installed Pulsar I updated for my 35” tires & verified speed vs GPS. I’m getting 14-15 city and 18.8-20.3 hwy at -75 MPH

 

[SilverSurfer15]

I have my speedo corrected.... and I’m sorry I don’t believe that. My truck wouldn’t even do that stock at 55-60 on the highway, 18s but not 20s.

I believe your dash says that, but I don’t believe the actual numbers are anywhere near that.

Did you hand calculate it?

 

[SilverSurfer15]

As a side update, I Switched to a forged 22x12 with same amp, seems like I lost a mpg or so on the highway. Not sure why, but I’m down around 12 ish around town at highway speeds. Maybe it’s just because it’s cold now.

I also bought a 20x9 0 offset with 35x11.50 terra grapplers. Mileage around town is near stock or maybe even better it seems if you stay under about 50. It drives really well on these, very similar to stock All around.

But highway mileage is still a tad lower, just did 1600 miles on these and seems to be anywhere from 13-16 depending on the speed and terrain. 67 seems to be the sweet spot for me, where I can get around 17 on the dash. 70 is about 14-15, 75 around 13-14 and 80 around 8-12 depending on grade.

I ended up averaging about 14 over the 1600 miles, and it was closer to 15-15.5 but I ran 80-85mph the last hour or because i was ready to get home and tanked the average lol.

I can’t imagine driving that far on the 12 wides, or what the mileage would be. So having a second set of all terrains or even all seasons is a huge plus IMO if you have heavy/wide/aggressive wheels/tires.

Few photos... it looks nose high in all these but it really isn’t

That’s a bitchin’ rig man. Really cool...

Thanks!

If it did get 20mpg it would be perfect lol.

Yep, did hand calc too and got same numbers +/- .1

Prior to all of my mods I was maxing at ~16hwy.
I did CAI & Borla at and time. Noticed small increase. Then added lift & Ironman All Country M/T and dropped to 14.
Added Pulsar, bed cover & swapped to Goodyear Ultra Terrain A/T. Huge ride improvement, smother shift points & lower RPMs at cruising speeds over 70mph. Feels like it rolls better with less road resistance & quiet vs both the old stock tires and especially vs M/Ts

Your picture looks great, one could shave in that reflection. I didnt realize that lifting hit the mpg quite that hard.

Probably just the illusion with the taller hood.
