Welcome to the group! Sounds like you've got the FD2 off-road package like me. I get in the area of 20mpg. But whether plastic or metal, I would never carry extra fuel inside a vehicle. If I had to carry extra fuel in my Patriot I'd do it on top in a roof basket or on a hitch mounted carrier, but that's just me. I suppose if I absolutely had to have it inside, a good metal can would be the way to go, those fumes can be very nasty!

 

I need a bigger tank that would solve a lot of problems hahahah

 

372 miles per tank sucks

 

Nope not the FD2 (Gas guzzling Crap) I have the 6 speed automatic (with simulated standard mode).



I have an idea

since nobody seems to make a extended range tank with an extra 3.5 gallon

( I KNOW THIS WOULD NOT BE SAFE LOL)

I was was wondering if anyone has ever thought of vertically stretching the bottom half of a new patriot plastic fuel tank by using a large flat heating element to soften the tanks plastic lower sides & bottom while applying about 20 PSI of compressed air to a sealed tank, to stretch the tank vertically about 2 inches to increase the tanks volume.

And to see how low the tank could be stretched and remain safe below the underbody.

Doing somthing like this would preserve Width & Length restriction (in the horizontal plane of the tank mounting points) while increasing the tanks volume in the vertical direction, maintaining the footprint of the upper under body where the tank is tucked into.

The only thing I think would need to be changed if the stretching idea worked, would be in Liquid Volume ratio of the float gauge. so that the fuel gauge reads true and extending the internal Transfer tube between the two saddles in the tank. this is cheap ass way to do it just to experiment

Any ideas ?

 

I would love to get 372 miles per tank! I only get around 220. Stretching the tank like that sound very dangerous, but from what I've seen on the underside of the Pat is that there is room for a larger tank, especially on the 2wd models.

 

I wish for 372 miles per tank....my wish hasn't come true ?

 

I don't think I ever got more than 330 and that was with a 2.4 FWD CVT driving easy on state roads, not expressways. I usually fill as soon as the low fuel light comes on so I've never found the bottom of the tank, nor do I care to.

My Wife may approach 350 miles with a 2.0 FWD 5-spd. She's a pretty easy driver with a 40 mile commute each way on rural state roads. I'm sure the manual gears help with fuel economy.

 

Thanks for that clue mr_et2 about the tank size of the 2 wheel drive patriot model.

also Is the Fredom drive II system combined with the CVT & 2.4 world engine that bad ? (220 miles) I know that FDII ate gas but i had no idea the range was that low. (check your manual and see if the range should be higher) you may need a tuneup & NGK plugs.

I was having a issue that left me getting 420 km (260 miles) per tank last fall, the cure was replacing the sparkplugs & doing a tuneup, the patriot was getting closer to 372 miles per Fill up after that FIX. downside NGK plugs are needed to maintain fuel effifcency and need to be replaced ever 50,000 miles or when the milage starts to drop off.

I also had a problem about (December 2019) 2 months ago with the patriot refusing to start after a fill up in cold weather, It turned out that I needed a crank position sensor, since the engine popped a P0335 code after the stall.

During the service for the failing crank sensor, a new ECM firmware update for 2015 - 2017 Patriot MKII & Compass (nafta market model) related to the P0335 code, that fixed a problem with gas blends using ethanol not being able to start or keep running below 32deg.F

Since that firmware update was done, the jeep has been rock solid, fuel economy slightly improved to about 376 miles over the rated 372 miles. based on my last 6 (clicked off) fill ups.

cheers

The EPA estimated fuel economy for the 2014 FD2 Patriot is 20 mpg city, 23 mpg highway, and 21 mpg combined, according to the window sticker. I drive mostly on the highway at around 70 mph, and keep my Jeep well serviced.

 

i forgot to mention that 376miles was me test driving the jeep until the jeep ran out of gas ( carrying 10 gallon Jerry can) to get back to gas station.

 

With my FD2 I get right around 20mpg/city in cold weather, warmer weather gets me around 21.5/city. Never really checked on longer trips. The mpg above is consistent before and after plug/air cleaner service/tires at recommended pressure.

 

JEEPED, I was also disappointed with the range on my patriot (4x4 2.4L) sport. I get between 22-23 MPG and fill up every 3 trips to work with about 10 gallons of gas. So my range is about 220-230 miles, which is very common for these rigs. There is space underneath for a larger tank but i think jeep was just trying to save money with a gas tank that's same size a Civic. In comparison to my other vehicles (from gas light on to full tank) my wife's Soul takes about 12 gallons and my Integra takes about 11 gallons. So Yeah i agree it has a small tank for its size/class.

 

Since i'm up here in Canada we do Km so:

the spec'd travel range for 2016 Patriot (2.4 L) (6 spd) (non CVT) (FWD) in automatic transmission mode
is 600 Km = 372.88 Mile

Real world I typically get 580-595 Km 369 Miles (running the tank dry)

To get that range (I am always speeding) lol

60km/h (37.3 mile/hr) (in city)

80km (50 mile/hr) to 90km (55 mile/hr) (back hwy roads with few traffic lights)

major Highway (100km) 62 miles/hr to 120 km/h (82 mile /hr)

these speed mainitain a fuel economy 11KM/Litre

not bad!

if I drive 40km hr (25 mile/hr) - 50km/h (31 miles/hr) as in city driving for an extended amount of time the fuel economy drops down close to 240 miles/per tank (if i run the tank dry that way)

not too good !!

I wonder if the Jeep hand wave is sign were stupid?

I want a 65liter (18 gal tank ) that give me 550 miles darn it!!

 

In find it strange that everyone here seems to be getting wildly varying numbers for (mileage).

I use Odometer one to track the total milage over a month of driving ( keep my gas receipts to know how much gas goes into the patriot each month.

use Odometer 2 figure out how much mileage i get from every quarter tank

I have also used the Odometer to check how much range I get from, Low fuel state to empty (run dry) that turns out to be 52 miles (bad news on a jeep that burns down in 25 mins)

BTW my jeep does not have the EVIC is there any way to switch the odometer From KM to Miles?

thanks

Without the EVIC I think you need the dealer's help.

 

I used to do it on my Pat when I would drive to Canada, back before I installed EVIC. If I remember correctly, with the normal odometer showing (not the trip odometer), press and hold the button for about 10 seconds.

 

Ok will give that a try thanks

 

A little undocumented trick for (Non evic models) I learned a while back:

If you set your dash board digital display to odometer and hold down Cluster button to
the right of the display for about 10 seconds the cluster will display elapsed running time of the
engine in hours in the following format {Hr nnnn}

this was somthing i stumbled on while reviewing feature of the jeep, this trick is undocumented,
very handy for knowing the running age of the Engine.

try it out let me know if it work on Evic / non evic models

 

I'm driving the standard 2016 jeep patriot would anyone be able to tell me about how many miles this thing can go on E ?

If possible city miles I'm always worried I'm going to run out generally K dont have a problem keeping gas in the tank but unfortunately I hot a hiccup like we all do Haha...

First off, welcome!

In answer to your question, it would be helpful to know exactly what drivetrain you have, e.g. 2.4 or 2.0 engine, a/t or manual,FWD or AWD, FD1 or FD2, etc. Those variables will have a tremendous impact on fuel economy.

For comparison here is my experience with two FWD Patriots.
2008 2.4 CVT -- high 20s MPG overall, I could squeak out 32+ on a long easy drive, maybe as low as 26-27 in the city.
2014 2.0 5-spd -- right about 30MPG overall, 33-34 on a long easy trip, rarely under 30 even in the city.

AWD and Freedom Drive options will be lower. I've seen numbers on here in the low 20s.

In my case that translates to about 300 miles per tankful.

What's a hiccup? Is your engine not running right? People tend not to change their spark plugs as often as recommended (30,000 miles). Changing Patriot plugs may be a little different from some engines, but they are an easy DIY project. Might take half an hour even with your kids helping and tossing a ball for the dog.

To find some threads about changing plugs you can use the search box above. It is dead center on the black banner above. Its easy to miss cuz its dark gray on a black background. It says "Search Community." Just type in "change spark plugs" and you'll get several threads.

Again, welcome!

 

I've got 2014 FD2 and when the fuel light comes on the EVIC tells me that I can go 20 miles... but I've never tested that.

 

that is Dependant on the configuration of the patriot you have

from the time your Low fuel warning comes on you have about 52 miles to before tank goes dry ( try turn off FD1 /FD2, keeping your speed above 65 miles/h to keep gear ratio high (lower engin rpm burn less fuel)gives little more time to find a gas station).

Generally if you have any patriot with Freedom drive I or freedom drive II your millage will often be a lot lower :-( off roading you wont get too far.

reason 1 if the jeep is travelling slower 25 - 35 miles/h as you would be doing is some sort of day offroading you fuel get eaten up 1st & 2nd gears ratios.

reason 2 the added demand placed on the engine by Freedom drive I or freedom drive II will knock off the millage even more

reason 3 the sometimes very slow stop & hold & Go nature of off road will result in worse than City milage driving

reason 4 running Freedom drive I or freedom drive II on highway for road driving in in-climate weather like snow reduce your mileage ( Probably not as much as offroading)

If your using standard you have some say in how gear ratios are used, this can improve your overall mileage if you learn to how to interpret the tach and engine sound.

Since I did my research before purchasing my patriot I avoided Freedome Drive I & II.

The 2.0l Engine mated to CVT trans driving FDI & FD2 apparently is the worst combination ( in terms of performace & milage) in the patriot line.

Ignatz is right: bad plugs will sap your Patriot milage big time ( i exprienced that in 2019)

 

I tried to contact FCA regarding dimesions of the fuel tank assembly , im seriously wanting to attempt redesign and fabricate a bigger fuel tank to add an additional 4.5 gallons, to do this i need some auto cad drawings files for the fuel tank and FCA just seems wholly un moved ! The only other way I can do this pull a used tank, use the 3d scanner at my local community college, and import the demensions into Auto cad then work from that. Any ideas on how i can work this problem thanks , I want my 500 miles per tank Dammit .

 

Here are pics of the fuel tank from a 2wd Patriot, top and bottom.

And here are pics of a 4wd Patriot fuel tank.

Even though the 4wd tank is physically longer and stretches over the rear drive shaft, it holds the same amount of fuel, which sucks. But, if you have a 2wd Patriot and were somehow able to modify a 4wd tank to remove the cutout section in the middle... that would add a good bit of extra capacity. Why Jeep didn't do that is a mystery.

 

thanks for the images can i get Somebody to measure the Width / length / height of a tank
so that i can establish the actual size in the photo then i can that info to work out the rest
of the measurements for the various shapes & contours of the tank,

If readers are able post dimensions could you also post the mopar Part number for the tanks as well along with the jeep configuration ie (Tral rated, FD1 FD2 etc

now the big question

How many version of the fuel tanks exist? ( I remember looking at a online supplier of tanks) and the patriot tank part number & interchange/compatibility list was quite long, bewildering with nearly 27 tanks P/N# versions split between the jeep Patriots (all versions) & 2011 - 2015 jeep compass. it would not suprize me if more tanks specs existed for the EU & Asian market patriot as well.

The jeep I run is a Patriot 4x2 (no 4wheel drive) (no CVT) that lives in Ontario, Canada

Comment: That tank is so far from the shape of a cube ( its a very a complex shape), does anyone think this is why nobody has tried to manufacture an bigger tank for the patriot.

thanks all

 

as for the mystery as to why, I suspect it was design contraints of the vehicle being a compact suv

 

THE STANDARD GETS CLOSER 405 MILES BECAUSE THE STANDARD LETS YOU DECIDE HOW AND WHEN TO SHIFT, AND WITH TIME... WHEN YOU GET TO KNOW HOW TO READ YOUR JEEP PERFORMANCE, IT SOON BECOMES SECOND NATURE TO THE DRIVER. STADARD IS A GOOD THING IF YOU CAN TOLERATE AND NOT PANIC WHEN YOU ACCIDENTLY STALL THE VEHICL ON A BUSY HIGHWAY /EXPRESSWAY STOP/GO TRAFFIC. IT NOT FOR EVERYONE BUT THE GAS SAVINGS ARE PROBABLY WORTH IT.

 

BTW COVID-19 SUCKS ! THAT WHY I HAVENT BEEN ON HERE IN ALMOST 9 MONTHS.

EVERYONE PLEASE STAY SAFE AND HANG IN THERE, WE WILL GET THROUGH THIS, WITH GODS HELP.

 

I don't mean to side-track the thread, but I'm concerned. Did you have covid?
