and NO wind or a tail wind.I don’t have screenshots handy but I’m not going to type outrageous numbers so I should be okay. I drove my JLU sport s manual with the 3.6 and a soft top from PA to California and back, 7500 miles through pretty much every type of driving environment one could ask for in August after I bought it. My best full tank was on a leg of straight highway driving through the Midwest. I got about 22.5 mpg. Through the trip, I averaged about 20.5. The worst averages were out west where I was fighting wind and driving in 80 mph speed limits. My overall average through the first 15000 miles is about 18-19 mpg. The best I have ever done in a Jeep was 26 mpg in my 2 door jk with a manual on a 75 mile leg of driving in a 40 mph zone. My only thought with these folks getting huge numbers is that it’s uninterrupted, relatively level or mostly down hill driving with the turbo and a 2 door.
engine ? tires ? gas ? Im curiousI average 24 to 25 around town and when I get on the freeway I set the cruise and get around 28 to 30
None of the dash readings are giving you the "true overall average mpg." The only way to figure that out is to calculate it by hand - see my post on page 7 of this thread. You know how many miles are on your odometer, and if you know exactly how many gallons of fuel you've put into it, you can calculate overall mpg.I dont understand why you reset the avg MPG. Look, you are after the overall ave MPG. Resetting simply gives you the average for that tank of gas. What you are after, is your jeeps overall ave mpg. Leave the reset button alone and drive your jeep . You will get the true average mpg. I have never hit the reset button and the reading I get is my jeeps true overall average mpg.
I also get 20 the highway but take it back on city roads with all these stop signs and I get below 15 mpg“Sahara w 35s putting up 20”! Like i said its has some un-wrangler-like mpg, still kind of surprises me.
Absolutely correct. It is disappointing that Jeep (both my Wrangler and my Cherokee do this) doesn't display a true running total - cumulative MPG. My Honda Accord does this, why can't Jeep?None of the dash readings are giving you the "true overall average mpg."

The computer is optimistic about your mileage to the tune of about .5 mpg. Additionally, as others have pointed out, the computer calculates a running total for the last -roughly- 500 miles. This bears out when I compare my Trip B average mileage (which I've never reset) to the average of the last 2 or 3 tanks versus what I know to be my overall mileage. Same thing for the fuel economy display with the green half-circle- if I reset that, it quickly (within a few tanks) comes close to what the actual average is for those few tanks (edit: and it matches my Trip B mileage, which -again- I have never reset) but is not the same as my actual overall average.
I know this was long-winded but the bottom line is that the one-and-only tried-and-true no-shit way to know your mileage is to record the number of gallons put into the jeep and compare it to the number of miles driven.
This is according to the computer, I don't care enough to actually measure it or keep track of it.What are people getting in city miles preferably big city miles. I live in Nyc and am planing to buy a jlu I only can afford one car. So it will be my daily won't be upgrading tire size unless maybe buy second hand Rubi rims and tires.
People always say the computer is optimistic. What makes people think the gas pump is telling you the correct amount of gas that you filled up with?The computer is optimistic about your mileage to the tune of about .5 mpg.
How can you be sure it's even gas?People always say the computer is optimistic. What makes people think the gas pump is telling you the correct amount of gas that you filled up with?
