And this is gas.

Depends, there's a power to weight ratio that affects mileage too.

I used to have a 1970 Torino GT with a 351 Cleveland engine. Had nice power, and with the 4 barrel set-up right, I would get over 25 MPG with mostly highway miles. Now if you kicked in the 4 barrel a lot, it would be in the low teens.
 
My 5.7L 6 speed manual Trans Am (3,440 lb) gets MPG similar to the 2.4L 5 speed manual Patriot (3,111 lb), but not all the time.
 
2.4L 5 Speed... See Fuelly below for averaging over two fill ups, i had to do some math to get the correct numbers for the oversized tires (245-65-17).

Over the past couple of weeks, I have been only going to about 2.3k rpm when accelerating and staying at 58mph (2krpm) on the road home. My mileage is mostly highway, i would say around 90-95% highway but it is a small town with many stoplights that i frequently hit as i am going by.

I highly doubt that with a 2L i would be getting this type of mileage, my jeep bogs down enough when loaded up with family going up hills and all that jazz, i couldnt imagine having any less power to drive this car
 
i just filled up for the first time with my new Patriot. I have a 32 mile rural commute with four stop signs and one traffic light. i got 28.7mpg for the first tank. i'm very pleased. i expect over 30mpg on the steady state cruising on the highway at this rate.

by the way, mine is a 2.4L 4x4 FD1.
 
Just bought a new 2011 Patriot 2wd with a 2.0. I would prefer stick but my wife's arthritis causes a need for the Automatic. First tank I drove almost all and got 24 mpg, this tank she drove and got 19 mpg. Sunday we are taking it to Dallas and hope to get better mileage.

Right now my Durango isn't much worse.

I test drove a 2.0, I found it spent way too much time in the 3500-4000RPM range when driving around.
 
Mileage is slowly improving but no real "Highway trip " yet. One thing that may be the problem. We live in East Texas and thee are a lot of hill, nothing steep just constant rise and fall. Even I 30 to Dallas. Maybe the trip to Galveston and San Antonio in July will show a better mpg.
 
just filled up,

29.7mpg 10%hwy / 90% rural commute.

"In God we trust, all others bring data"
 
I had to calculate mine out because of bigger tires, had to do some math to get it right, but it all comes down to foot control and rpm limiting. My figures on fuelly are for bare minimum gas pedal pressure, and not excedding 2k rpms period. I was able to achieve 31.1 mpg by doing this.

In reality, i probably sit more at the 26-28 mark for normal unrestricted driving.
 
i do the math because i can...

seriously, all mine are calculated, and i believe actual.

i just filled up again, only 27.5 this time. it's been hot and i used the AC a fair amount.

i'll suffer in silence.
 
I'm getting 25-26mpg with my 2.0...about the same as the 2.4 had been getting (see signature). The 2.0 rides in the same range, about 2250 rpm @ 70 mph...one difference I notice is the 2.0 seems to downshift more for inclines than the 2.4...Have only had Riot II for a month, first highway-only trip is next week...I-75 has to climb quite a few hills from Detroit to northern Michigan...but I hope to at least see the upper 20's. I don't expect to get anywhere close to 30 until summer. The previous 2.4 had only one tank that got 30.3 mpg....I don't kid myself; getting 30 mpg is gravy for the Riot...that I can fill er up for about $40 is a nice feeling in itself.

Once the stock Eagles bite the dust, (30-K on the clock) I hope to locate a set of alloy rims and just use the steelies for snows. I really miss my Hankooks...
 
It really is a matter of an overworked engine is not an efficient engine. The V8 Commanders get as good or better mileage than the V6, but only if you don't use the extra power offered by the V8. For example, If you have the 5.7, but you never accelerate faster than you could with the 3.7 V6, you will get better mileage that the 6. If you constantly try to push the 6 to the limit, economy will suffer.

With the Commander, due to the massive vehicle stature, every start from stop is a workout for the V6.
