Most of us on here had horrible gas mileage until we got a good couple thousand miles on the engine. I myself only saw 18mpg when new, but after about 3000 miles, I was getting 22-23 mpg around town (mine was rated at 21mpg City). Now some of that may be from break-in, some from the computer "learning" your driving habits, and some from learning how to drive a CVT equipped car, but don't despair just yet. The mileage will get better. Also these engines love heat, so while it may not be the heater blower fan directly, it is pulling coolant temp out of the engine.

I have a scangauge II hooked up on my Patriot, and in the winter I've seen the coolant temp stay at a steady 172 deg F. Some members have made up radiator blockers to get more heat into the motor, and thus also increase fuel economy. Myself, I remove the battery cover/fresh air duct which makes the engine breath the heated air under the hood. It helps offset the winter fuel mix, which will drop your fuel economy 1 or 2 miles per gallon.

Oh and don't rely on the EVIC just yet. Do the actual calculations on miles driven vs. gallons of gas pumped in. I'm pretty sure the EVIC only does average MPG and it may need to be reset or something. Especially if one of the dealer lot hounds hot footed around in the thing prior to you buying it.

 

Low mileage, cold temperatures, and winter mix fuel... all are going against you.
Hang tight till this summer and see what you can get.

IMHO, the perfect conditions for the Patriot are about 70°F, summer gas, 50-60mph speeds max. With those, I routinely beat the sticker rating by 2-3mpg.

 

Thanks for the response, guys. I did reset the EVIC to zero out everything. I'm just shocked at the cruddy mileage when I bought it specifically for good gas mileage. I sold my Ford Explorer three years ago because it got only a little worse mileage as what I'm getting now with this Jeep.

 

Have you been wearing your heavy work Boots ? I never beat the sticker rating, heck I never have gotten the sticker rating except driving downhill from the Mountains. Oh well.

 

Mmmm...obviously, is too new to get good mpg, any brand any car.

2nd, I noticed: the way that you normally drive, is a little bit different in the patriot. When I bought the pat, I got the same mpg than my Liberty 3.7 v6... but I learned to drive this jeep, and now I really love the mpgs. I own a charger, 5.7 hemi right now, but a couple of years ago, I owned at the same time the SXT with 3.5 v6, and guess what?? I got better mpg with the Hemi.

So, the weather conditions, how you drive, size, weight...manual, auto, CVT or autostick can get better or worse mpg.

 

You guys mention learning how to drive the CVT. I'm pretty new to the forum. How about enlightening the newbs with what you mean?

 

driving the cvt



As you may have learned yourself the cvt seems to really suck some power from the engine especialy in acceleration and passing vehicles. i think they mean watching your rpms, to increase fuel mileage and acceleration because of the tip-tronic option (Manually shift able automatic). the lower your rpms on the free/high way can increase your mileage dramatically. also when you use the manual option you can granny (drive at low rpms on straight aways and really get good acceleration by learning rpms.

this is just what i thought they meant i could be wrong. hope this helps.

 

Check my Fuelly numbers for the first two tanks-horrible!!! Now here is a question? I've been getting 10.5 / 10.6 L/100km during the winter and then I did the computer reset and I got 9.7-huhh???? Next tank it went right back up. I reset it again and I'll wait to see what I get this time.

 

I have 25000 miles on my Pat and mileage never increased.. With the slightly bigger 215/65/17 tires it has actually dropped to 20 city 23 highway. With the 215/60/17 tires i got between 21-22 city and between 25-26 highway.

 

I hope you guys are right about the engine just being new and the gas being a winter blend. My low fuel light came on today and the trip odometer indicated a total of 183 miles driven! I haven't filled the tank yet, but depending on how low the tank really is it could come out to 15-18 mpg. Granted, it was all city driving, but come on! My 99 Cherokee I replaced got the same mileage. Here's to hope.

 

I´m pretty sure, your engine is to new. Or you have a heavy foot!! LOL just kiding.

I got 24 mpg CITY, driving very slow...well, not to slow. I try to keep my tach in 1,500 rpms always in city, to get 24 or 24.5 mpgs. If you feel something wrong, ask the dealer

regards and good luck!

 

I bought my 2011 Patriot Sport 4x4 FDI CVTII on Sunday 1/16/11. I went over 200 miles to a dealership to get mine. On the way home I went 176 miles on the interstate at 70 to 80 MPH then another 56 miles on 2 lane roads for a total of 232 miles. I filled up before I got home to start the week off with a full tank. I was able to put in exactly 10 gallons so 23 MPG on first tank. I have a long commute everyday and so far I have around 220+ miles on the second tank of gas and still have a little over a 1/4 of a tank.

 

I have the 4x2 with 2.0 and CVT II. I've been getting around 23. My commute is aproximate a mile or so of city driving with 6 traffic lights, then around 13 miles of highway at 70-75 mph, then 6-7 miles of 60 mph highway, then another 5 miles or so of city driving with another 7 traffic lights.

That said, mine just tipped 1000 on the odometer. I noticed this morning that I've gone 160 miles and still have a half tank of fuel so I'm thinking my mileage is going to be a little better this time.

 

2011 Patriot Sport 4x4 FD1 with CVT11
Just filled up my second tank full. I drive 80 miles a day.
70 miles on 2 lane roads and 10 on four lane.
Had 301.4 on that tank and filled up with 11.50 gallons
26 MPG compared to my TJ with 6''lift on 35's
epper:
WHOOP WHOOP

 

2011 Patriot Mileage

Just came home from a 600plus mile trip - mostly highway driving. 1650 miles total on the Jeep so far.

Fuelly tracking is looking good....
2.4, 4x4 CVT.

Basically I let the auto shift do its thing for the most part and keep the RPM's under 2-3k when possible. Basically 55-60 mph on the highways. No jack rabbit starts. I came from a 2007 Pontiac Grand Prix GXP V-8, yeah it could do 0-60 in under 6 seconds, BUT it cost ya....got about 14-17 average in that puppy.

I will take the 25 mpg average of the Jeep

Oh yeah, took the Patriot to OBX - spent a day out on the northern 4x4 beach - it was rough, but the Patriot did OK... kept up with many of the big boys, several people stopped to ask how it got out there! The fully running average includes the day driving on the beach in 4x4 locked mode in low gear, high RPM to keep the torque up, so I am really happy!

 

29mpg in the summer, 27 in the winter average with 50% city 50% interstate driving

 

2011 Latitude X, FDII

5300 miles
21 fill ups recorded
Combined AVG = 22.93
Best tank avg = 25.48
Worst tank avg = 21.39

 

I bought my 2011 Jeep Patriot Latitude 70th Anniversary Edition 4 x 4 1 week ago and I have 1300 miles on it and I am averaging 25.6 miles per gallon. I am very happy with this

 

I got a 2011 Latitiude 2.4L CVT 4WD FDI in August. My Fuelly average is 23.6 MPG but it doesn't have the last fill as part of it( can't recall exactly what I got but it was low 23's again as memory serves ). I have about 1300 miles on the vehicle now.

Worst tank = 21.4( a good 50% + of the tank was towing my boat )
Best tank = 29.7( 90% highway run in CC @ 60 MPH )

Winter gas is here now as are colder temps so I expect to lose anywhere from 1-2 MPG until next spring. I DETEST winter gas. It absolutely KILLED my MPG when I had my 5.3L Silverado's and HEMI Ram's.

 

After 2 months of driving (3800 mi) I am thoroughly unimpressed with mine (sport 4x2, 5 speed, ac, cruise only options.) I'm averaging 18mpg town, 24 hwy. I don't drive like an idiot, but when I take off from a stop, i'm not driving like grandma either. The vehicle gets worse mileage than my 1997 VW Jetta (vr6 at, loaded 25 town, 31 hwy.) I have a bud at work with an 03 Liberty getting 31 hwy/25 city.....with the 3.7.......WHAT GIVES?! Can we reprogram our chips to the euro setup? I grew up on ford and Dodge....Mopar has NEVER let me down, until I bought a new car.......Next new rig will definitely NOT be anything related to the caliber.

 

Your bud with the Liberty is pulling your leg. Are you getting your numbers from the EVIC?

 

I'm averaging right about what the sticker said.

 

4X2 Has its place

If you don't offroad, don't do the outdoor thing and don't have snow, there is no reason to go the added expense of a 4X4. The people I know who have 4X2 Patriots and Compass got them because they liked the Jeep label and look and see their vehicles as excellent small station wagons. There are a lot of hatchbacks around but not many small station wagons. The 4 wheel drive function is only part of the vehicles utility. Most other makes don't offer a comparable sized station wagon as they want you to buy their SUV line. I know you can get 4X2 Escapes, and other brands, but they price out much higher than a 4X2 Patriot. Easy to load, carries a lot of stuff, has a lot of options for racks and hitches and the 4X2 is competitive in gas mileage with hatchbacks.

 

I just switched to 89 octane fuel to see if a little less spark retard would equate to better fuel economy.

 

With a modern vehicle you need to do at least 2-3 tanks to give the computer time to relearn for the new octane before you start checking the MPG. If you can reset the computer before using a new octane it makes it learn faster.

I actually ran 89 the other day as the 87 pump was down. The end result was no MPG bump but I did not expect one after just 1 tank.

 

I ran 91 octane for 5 tanks and didnt notice anything, so i went back to 87.

 

I bought my 2011 FDII CVT Lattitude in late October. It now has 3200 miles on the clock after a long holiday road trip. My mileage improved at least 2mph from the first thousand miles to the last. I'm getting 20 city / 22 hwy at regular speeds of about 70-74. I've learned these cars suck horribly over 75.

 

All vehicles will lose MPG at those speeds not just Patriots.

 

Well I know everyone else has already said it. I will too just because I had the same thought when I bought my Patriot. The engine does take a few thousand miles to break in before you get the better MPG. I drive to the beach once every few months and its roughly 200 miles to where I want to go. I usually end up with slightly less than a quarter tank of gas. I could probably do better if I had a lighter foot on the interstate.

Give it some time and try a few different things. I noticed after I got used to not flooring it at Green lights and taking a little longer to build up speed. I saved a lot in MPG. Lately i've been getting roughly 24mpg.

My Fiancee has a 2012 Hyaundai Accent and that car gets 38mpg driving to the beach with a 2.0L. I was really impressed with that.
