Hi everyone, im new to the site because i was trying to find some cool mods to do to my patriot, i posted in the newbie part but no1 has responded, anyways i was wondering how i have seen some people say they are gettin 34 mpg.. im only getting about 20 mpg.. is there a way to increase that? btw if any1 wants to inform me of some cool mods please feel free ive got a '07 black limited, keep in mind im only 19 and yes im paying for this, didnt have rents to spoil me with it but i want to kind of dress it up ya know?? and i have seen speak of crd or something for better gas mileage what is that?? im sry im young and not good with cars just never really had any1 to work with me on that kind of thing.. thx in advance..

Welcome to the forum, xuscballx. The crd is the diesel engine, not yet available in North America. The high mileage you're referring to was probably from a diesel. 20mpg is a bit low. A Patriot with the off-road package should do a bit better than that. My 4wd with the cvt and without off-road gets about 26.5 on the highway. 2wd with standard trans can get up to about 30. Mileage is influenced by a lot of things. Stop and go city driving kills your mileage, as does aggressive driving. Your mileage may improve after you get a few thousand miles under your belt.

city driving (ie lots of stop lights) drastically reduces your MPG.
Try to keep the revs below 2500 whenever you drive it, so no more putting the petal to the metal.
I installed a K&N air filter but it really didn't have any effect on MPG but it did give it more pickup.
One thing you need to look into is gas quality.
Alot of gas stations now sell gas that contains 10% ethanol. You WILL get poor fuel economy when you run that crap compared to 100% gas.
My first tank of gas was the 10%. I filled up tanks # 2, 3 and 4 on real gas and now I am on tank #5 now running 10%. I wanted to see after I had a few miles if there was a huge difference or not. Well, there is.
I drive 45 to 50 MPH for 7 miles to work.
On regular 100% gas I get 26 to 27 mpg on the way to work.
With the 10% ethanol, I get 24 to 25.

i didnt realize they did the 10% ethanol now.. whats taht for?? and my driving is typically open road minor traffic, thats why i was wondering why my mileage was not that great.. i thought about the k&n but u said its not much of a help.. is there anything else i can do?? and how about power?? anything i can do for that.. i have my lil 4 cyl and its just not fun sometimes.. but im sure with that power iit would reduce the mpg but you gotta give a lil to get a lil i guess.. it would be nice to reach that 24 mpg like you have neil but i dont see anything else i can do.. any1 know any mods i can do for looks?? and once again thx for the input you guys/gals

I live in mostly flat country.
If you live in a hilly area that will cause your MPG to be less.
They started putting 10% Ethanol in Gasoline because it lowered the price they could sell the gas for. Gas stations are cut throat. A penny per gallon makes a huge difference. People will drive a extra 1/2 mile down the road to save just a couple of pennies per gallon even though they waste that savings by driving down the road to get it.

Are you checking your MPG using the EVIC??
When it says AVERAGE MPG, hold the reset button in until it resets.
Do this when you are out on a highway trip. Keep the MPH down to around 70 and see after 10 miles what it says.

The ethanol in gas is to reduce emissions not to burn the consumer. This was not always the case, before widespread use of ethanol it was MTBE (an oil product) that was used. MTBE has/will be banned (but big oil has made that difficult). MTBE is toxic and very water soluble. Just a little leak from an underground tank can contaminate vast supplies of water (California was one of the biggest markets because of the emissions reductions). Most areas only had fowl smelling water, a few did have areas that were above EPA acceptable levels.

Ever notice that no matter what we as humans try to do to "save" our environment our "solutions" seem to be just as bad but in a different segment of the environment. Kind of like the hybrid people that think they are doing a great thing for the environment, choosing to ignore how much detriment and energy it took to make that battery. Sorry, leaving the soap box.

You are one of only a few who get better mileage than I do. I'm very curious what you are doing that I am not. Hmmmmmm

i only dream of that

Go easy on the acceleration (from a stop and speeding up) in the city.

On the highway its pretty easy to get 25-28mpg by staying below 64mph or so and if you use Cruise control. The Patriot is not so aerodynamic so high speeds affect it.

If you drive only in the City, 20mpg sounds about right, since idling and accelerating burns lots of gas.

Also, if you have the Cross bars on your Roof rack, remove them and you'll have less drag on the highway

I didn't read your original post so I'm not sure if you have a 4x4 or the 4x2. If you've got the 4x4 you simply won't get the mileage that us 4x2 owners get. Different gear ratios and more moving parts (friction) will lower your mileage. But even so, the advice given above will help. The thing about the Patriot is that it wasn't intended for flat out acceleration so if you're looking for a good green-light punch, you're not going to get it. :(

Do you have a manual or the CVT automatic? I've got the CVT in mine and it takes a while to learn the power curve. If I stomp the pedal to the floor, it bogs down... BUT if I stomp it HALFWAY down, I can chirp the tires and it launches from a stop. Not Corvette acceleration, but pretty good for a 4-banger powered SUV the shape of a brick.

I just drove about 800-miles around the state on vacation, from 2,000 ft elevation desert up to 8,000 foot pine trees, mostly highway with the a/c on, and with 40mph crosswinds most of the time. I averaged 29.5 mpg and even had it up to 32mpg at one point. I don't think the roof rack cross bars make a bit of difference. I have them and they don't seem to affect anything. I think the windshield pushes the air over the low-slung bars. However, I notice a HUGE difference in highway mileage when I have my bike(s) on the roof. With them up there I usually only get about 24 on the highway.

If your Pat is under 1500 miles, the engine is still breaking in. I saw a significant improvement in mileage after that point. Keep your tires aired up, go easy on the throttle, and try to be as "smooth" in your driving as possible. Anticipate lights so you can decelerate slowly rather than have to slam on the brakes, etc.

Good luck and enjoy the Pat~

I consistently average 27 mpg (combined city/highway) and I do a good amount of city driving. I take it easy when accelerating, typically trying to keep it below 2500 rpm's. I have put 3,000 miles on the Pat so far, and just got the first oil change, and k&n filter, so I think my mpg's might go up a little bit! I have the 2.0L 4X2

im doing somethin wrong then ive got the an automatic 2.4 4x2 and im only getting around 20 mpg in rural i dont gun from the start i drive roughly 55-65 is there chips or anything u can install for better mpg?
 
#36 ·
A wise experienced repair man once told me "Just because it is new, doesn't mean it works"

Perhaps your car was build with a defective oxygen sensor or faulty chip that causes the transmission to rev too high. A 4x2 CVT should get at least 27 in normal driving like that. A problem like that may not trip the detectors on the code scanner though. You will need a good, motivated seasoned, dealer mechanic to figure that one out. Good Luck.......

I disagree

I have the 2.4 4x4 5spd and now that the warmer weather is here my mileage has really shot up. Last tank came out to just over 31mpg. I think Jepstr67 and I are both from WI and we both get pretty good mileage (over the EPA rating at least) so I am not alone on this. Maybe the fuel formulation is different in this part of the country? All gas here is 10% ethanol.

Then again, it may just be experience. Jepstr67 sounds like hes been around the block a few times with a variety of vehicles and I've been driving manual transmission for 30 years and even drove OTR tractor-trailer for a few years so maybe we just know how to get the most out of the old pedal and stick.

This is probably true. I have always been able to get a better gas miledge out of the cars when i drive vs. my GF. We recently took the patriot to virginia from ohio and i was getting 27 mpg while driving, she was only able to get 22. It really depends on the driver.

My last tank was still around 27 too :pepper:

I just purchased my Pat, 4x2 Limited 2.4L CVT II ... Right now the little guage on the dash reads 23.6 MPG which is almost spot on. I just filled up yesterday, it took 12.29 gallons to shut the pump down and I had 290 miles on the trip meter ... so 290/12.29 = 23.6 exactly.

I just ordered my K&N, and plan on switching over to full synthetic on my first oil change so hopefully the MPG only get's better. I'd at very least like to see 26 MPG because that's what I was getting in my Pontiac G6 GT which had a V6 in it ... but then again I drove that car like I stole it!!! :)

I've had my Patriot since yesterday afternoon, and have driven it a little over 140 miles. I won't know exact mileage until I need to fill up the first time, but my best guess at this point is that I am right around 25. Mostly all around town.

I have the 4X2, 2.4L, with five speed manual. I usually shift around 3-3.2K rpms. The get-up-and-go is plenty for me, and mileage is a far cry better than my other Jeep (about 15 in town). I'm hoping to get 30 or better on long highway trips, as I make a lot of them, and that's what I bought this for. I'll be making a trip from here in Cleveland, to Belmont, MS and back in about a month, so I'll know for sure after that how great my vehicle buying decision was...

That shifting at 3k will cost you. Most of us getting good figures in town are shifting at 2k. The highway numbers are pretty good on Patriots, 28 to 31 is common for 5 speeds.

wifes 07 patriot gets about 28 h/c. We live 35 miles from her work. Then she sees her poeple. Home health nurse. She drives about 60/80 miles in town . Then a drive home. Bought new in may 2007 now has 29,000 miles. No problems so far.

Good Mileage

My 2008, 4x2, manual Pat has 10,000 miles. I was getting 28mpg consistantly from about 5,000 miles. I recently cut 16 mile commute speed from 70 to 60 which kicked mpg up to 30mpg. Last weekend I went on a road trip and kept speed at 60 (much to my chagrin.) Was pleasantly surprised that mpg averages 31.9mpg. I am very pleased with mileage though keeping speed down is definitely not for me. Holding the Pat down with cruise control is like holding back a race horse.....granted not Big Brown.

If nothing else it might subconsciously make you drive more carefully/slowly, which might be beneficial. I've found simply keeping my dash display on the MPG setting helps me get better mileage, because I can see how feathering the throttle and such can at a 10th of a MPG pretty quickly...and over a tank those can add up.

milage

some of the 35-40 mpg patriots you here about are probably from Canada(larger imperial gallon) . I just drove my new 4x2 5 speed from Clagary to Princton , throught the rockies and averaged near 40 mpg( 7.oltr/100km) with the a/c on . I also have found the seats to be the most comfortable seats I have had yet. This is my first North American vehicle and I am happy so far
