Sitting at about 16.5 mpg, ‘21 MaxTow only about 500 miles so far most back roads

Stock Sport S Max Tow was getting about 18/20hwy and 13.5mpg towing a 5K lb travel trailer. Lift and 35s added and now averaging 14/17, but still around 13.5 with trailer! Happy about that! Commander was getting around 12/15 empty, 8 with trailer.

I have about 860 miles on stock JT Rubicon with 2" mopar lift kit installed (35 tires and rims not mounted up yet). Almost all highway with cruise set between 65 and 72. 13.9 mpg average. ?
MT tires. Extremely disappointed. Where is my advertised 20 something mpg?

Don’t use the cruise, my experience is I can get better MPGs without it. Also it’s a little late now but you should NEVER use the cruise during the break in period, varying your speed is important during the first 500 miles.

I've had mine since October, Sport, max tow, and a manual transmission, autostop off. Average mpg 19.9 city and highway together with winter blend fuel. I had 2 tanks with summer blend, got 21 mpg.
The one tank with just city driving and winter blend fuel 13.5 mpg was just depressing, but there was wet pavement so the other drivers were freaking out and crawling between intersections.

I have a stock Rubicon, about 1,000 miles on it, with a tonneau cover (don't know if that is worse than having the air bubble cushion you get with the tailgate up.

I'm getting about 13 MPG running errands around my neighborhood. I can't even call it "city driving". I also do a remote start almost every drive for past couple months.

I've only had an opportunity to get long distance on the highway a couple times now. Cruising at 75 MPH, I got only 17.5 MPG. During some slower cruising at 55 MPH, I was getting 23.5 MPG. It was a huge difference on the computer as soon as I slowed down.

Noticed the same huge difference on long drives. Coming back from Fort Wayne a year ago once we got out of the 55 and 60 mph speed limits and my wife nailed it - you could see the current and average numbers drop.
Anything over about 60 will kill mpg. Since the wind resistance increases exponentially, once you hit that point it's almost all totally up-hill.

Dont base your MPG on the dash read out. Mine always about 2 MPG better than actual. I always use miles divided by gals.
Do the math to get a accurate mpg.
my $.02 worth.

Interesting. My dash always shows higher than actual.

I'm getting 13 city 14-15 highway
JTR w/ stock 4.10s, 8spd auto, running Milestar Patagonia MT 37x12.5
Speedometer has been recalibrated.
MPG is worse than I anticipated.

 

[ShadowsPapa]

You can't calculate it based on one fill up. Not with these fuel tanks.
These are the most inaccurate as far as telling when they are full based on the nozzle.
My read-out is really quite close to reality, and the odometer I have found to be spot-on.
But I have to keep squeezing the nozzle to ensure I fill it fully and average out at least 2 or 3 fills.
With my cars and other Jeeps, when it's full, it's full and you can see the gas up there. On these it will shut off when there's anywhere from 2 to 3 gallons of space left.

No surprise with those tires. The weight, rolling resistance, meat on the road - it's not going to be good.

I've seen people running 37s claim they get 16-17 w/ stock gears. Now I'm thinking they are probably running AT. If I knew this sooner I would've went with ridge grappler...
