For those that have a 2012 4x4, what are you getting for mileage with your Patriot. I know the window sticker says 21 city, 26 highway (for CVTII auto trans). I have checked mine the past two fillups and I am only getting around 17 mpg, 90% short trips (I drive 1 mile to the office). And I have yet to use the 4x4 lever, so it's not that.

My question, have any of you with 2012 4x4s checked your mileage. I would like to compare. Thank you.

If you're only driving 1 mile the vehicle is never getting warmed up and will have very poor milage. Basically until the engine is at normal operating temperature it will run rich, "wasting" fuel. What was your last vehicle and what milage did you get out of it on the same driving cycle?

my last vehicle was a 2001 Sonoma pick-up. V6, 4x4. That got 13 mpg. I understand the whole warm up thing. I'm just curious what others are getting in "city" conditions. I have had my Jeep for a month now and it has 500 miles on it, so I don't drive it a ton. Again, I am just curious for others with 2012s and the mileage they get.

The way it was explained to me is that the computer derives a fuel map based on how you drive.
How many miles were on it at purchase.

test drives, lot boy moves, dealer moves...all get logged into the computer.
so your fuel map is not altogether yours, you know

So, you should to a re-set on the main computer, follow the break in procedures and know that most everyone is reporting better gas mileage as the vehicle accumulates some miles.

Mine is posted at 38 Imperial MPG, highway. Ièm getting all the time 30 MPG and that is with lots of stop and go and lots of crawling up and down logging roads, industrial roads with a blast of highway up and another back down from my route.

Ièm OK with that.

38 miles per gallon or liter? And do you mean kilometers since you are in Canada? According to Jeep's website the miles per gallon for this vehicle should be 21 city, 26 highway. And I'm afraid I have no clue what "imperial" is. Is that your level of quality in gas selection similar to regular, plus and premium here in this country?

The more I research, the more paranoid I get. I had to drive the highway home when I bought the Jeep. Was not told at the dealership to keep it under 50, so naturally I drove the speed limit. Now I'm worried I may have done harm to it doing so. Paranoid or warranted?

US gallons are smaller than Imperial gallons.

30 mpg Imperial is close enough to 25 mpg US.

No I do not mean kilometres, I meant what I posted, miles per gallon, measured in Imperial units.

The take away for you should be that a vehicle, in Canada, rated at 38 mpg highway is getting 30 combined with lots of stop and go, lots of hard industrial roads. Our logging and industrial roads up here are what a lot of you would call off-roading down there. Can be great but often are brutal, especially if they haven't been maintained in a while. They aren't gravel, they are blast rock for instance.

And that everyone on this forum reports they get better fuel mileage as the engine breaks in.

Gas in Canada is sold according to octane with what you call regular at 87. mid is 89 and premium is 91.

no need for anything other than regular in the Patriot engine, ever.
Except I run fuel injector cleaner through with 91, just a tank or two a year.

From a 2011 Jeep Patriot OM...

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided.

I think you are okay.

Think of the millions of new cars around the world, how many of those drivers do a break in period as opposed to get in and go?

You will be fine...the important thing in early days is do not spend all your drive time at a single RPM, vary the RPMs up and down.

the only other thing I might recommend is to do some full throttle pull downs/ without lead in the gas anymore I'm under the impression that helps seat the rings.

Maybe, maybe not but it only takes a few seconds on a drive.

Get going, fast under full throttle but in say third. Once you are at terminal velocity just lift off the gas pedal fast and allow the vehicle to coast down, using engine braking. repeat.

(Make sure no one is behind you)

You should be in a low enough gear to feel compression slowing you down but going fast enough that it actually lasts and does something.

But the number one thing is vary your RPMs for the first while...it would be a long trip on cruise control on a new engine that would shorten its life.

Burn a tank or two of gas doing crap like that before you even begin to check mileage.

It's hard to vary the RPMs with the automatic CVT. It tends to go up to about 3000 and then it drops down to 2000 fairly quickly. I suppose I could do the "autostick" thing to accomplish this. Not really sure why that is even included other than for people to feel cool like they are shifting a car like in the "fast and furious" movies.

Man, you really need your hand held through this, don't you?

Of course you use the auto stick for what I recommended.
That is what it is there for, you have either an automatic or a clutchless shifter in basic terms.

Third is third, no matter on a manual shift or a CVT with the indicator reading third.

You ask too many questions around here without reading the owners manual or searching the forums and argue and piss and moan about the answers you get, folks stop answering your questions..you know?
