Is the site below realistic? The '07 4WD CVT tranny is listed for 23/26 mpg city/hwy . There is a listing that is lower, but I figure (hope) it is for the CVT2L model.

So, can I really expect mid 20's mileage? My driving drive will be 95 miles/day 95% highway, about 50/50 2-lane and Interstate, 55-70 mph.

I am eharing,
"yeah yeah, you'll be lucky to get 19-20 mpg".
Advice/opinions are appreciated.

Yes, the lower listing is for the CVT2L, FDII.

The CVT is geared a lot taller in its highest gear ratio. The engine spins around 2100rpm at 70mph instead of 3000rpm for the 5-spd. Yet is still gets worse FE. Actual FE has been reported on here by owners with the FDI CVT is anywhere from 23mpg to 30mph for all highway. The Patriot is not very aerodynamic, so driving at 55mph vs. 75mph there is at least 15% more fuel used at 75mph. Because of the CVT, there seems to be a wider variance from owners. Those who are diligent on watching and limiting engine speed below about 2500rpm and below 65mph are getting mid to high 20's.

Thanks for that reply... makes sense, and is good to hear. 23 would be an improvement of 8 mpg.
I've learned to "keep control of the right foot" w/ the F-150 when I am watching mileage!
That "V-squared" thing, I know ...........

Mine is the FDII, and I usually average around 24MPG, about half city half highway. And I'm usually at 65-70 on the highway. I've seen folks on here with the FDI getting 27 or so MPG.

My mileage since new is in my signature. That's with the FDI 4X4, five speed manual, and probably 90% freeway or highway mileage. I drive for gas mileage. That means shifting most of the time to keep the RPM between 1500 and 2500. I rarely drive over 65 mph.

I have a Scan Gauge which shows my Manifold Pressure which is the pressure in the intake manifold pushing the air fuel/mixture into the cylinders. I accelerate with accelerator pedal pressure such that the butterfly throttle valve is rarely fully open. The Patriot has "throttle by wire". The computer takes the accelerator pedal position as an input reflecting the driver's power desire and controls the butterfly valve in the intake system. So there is no physical linkage between the accelerator pedal and the butterfly valve.

Pushing the accelerator pedal halfway when accelerating doesn't mean that you are using half throttle. The Scan Gauge typically shows full ambient pressure in the intake manifold with the accelerator pedal just partways depressed. So I manipulate the accelerator pedal to get a max of about 10-12 PSI manifold Air Pressure when accelerating. Ambient pressure here at my elevation of 800 feet above sea level is about 14.2 PSI.

I am willing to get there a very few minutes later to send less money to the mideast terrorists.

'good info. I can feel that type thing in some vehicles. Do you have a photo of your gauge in your Patriot? That's doggoned interesting.
Thanks!

That is key in the Patriot. I have a 5-spd FDI as well. I have heavier 18" wheels. I shift over 3000rpm more often than under. I try to maintain 80mph on interstates in Michigan. I've hit the rev limiter in 3rd many times on freeway entrance ramps. I have been getting 23-26mpg for the first 25k miles, which has dropped off lately by 10%. Maybe because I am driving even harder, maybe something changed with the vehicle. I'm not concerned much with it. I am certain that I could eek out 30mpg for a whole tank if I changed my driving style. Not worth it to me.

Those are good numbers. The more you keep an eye on the tach, and keep it under 2k on acceleration, the closer to 30 you will get. At least with the 5 speed, I see little difference between 65 and 70 on MPG. The Patriot likes to be at least 190 engine temp to get the best mileage. Most Patriots get the mileage figures on the window sticker. There have been a few owners with poor economy for no obvious reason.

You will be happy with the Patriot for a long commute. It is good in snow and easy on fuel. My Patriot has bee very reliable.(accept for mice eating the wires)

That's good to hear. Honestly, it seems that we are choosing between a Patriot and a RAV4. We have had Toyoyoes in the family since '81, can't count how many. "Jeep" is an unknown to us, except for a foray with a 'project" '76 CJ5, that scared my soon-to-be wifey plumb silly.

THanks for the reply.

hey i devide miles driven between fuel ups and devide gallons by that and get 22mpg so im getting little better on highway and little worse in town so i figure 20 town and 24 highway so its good for a full size 4x4. ;) but its only a 13.5 gallon fuel tank so it feels like you fill up more but its just got a tank from a ford focus. so its all good.

If it has a Ford fuel tank, will the 25 gallon tank from my F-150 fit???? :pepper:

Still, thanks for the reply.

Here are some pictures.

The first is idling in the carport at the end of a trip. The gauge is showing MPG, which is 0 because the car is not moving, MAP (Manifold Air Pressure), FIA (Intake air temperature Fahrenheit), and FWT (Coolant Temp Fahrenheit). The difference between intake air temp and outside temp is eleven degrees.

The second is at cruise on level road. The difference between intake air temp and outside air temp is 4 degrees. I think the Patriot has a pretty good cold air intake from the factory.

Third is going up a hill, Fourth is going down a hill, and Fifth is with the throttle floored, showing what is essentiall Ambient air pressure here at 800 feet above sea level.

The Scan Gauge plugs into the OBDII connector under the dash on the left side. OBDII stands for OnBoard Diagnostics II. Iv'e used the same gauge on our 2006 Mercury Grand Marquis and my brother's 2002 Chevy Tahoe. I paid about $170 for mine.
