1st full tank run without the extra heavy right foot acceleration.This shows an increase of just over 1.5mpg with the new lighter wheels and tires.(the D5 sport edition wheels come in at a tad over 18 pounds apiece, the tires are a full pound lighter than stock goodyears @23 pounds each (41+ pounds each combination vs 50+ pounds for steelies with the Dunlop Graspic snow tires)
I have kept records since day one and my mileage after 45,000 miles came in at 29.8 mpg total. Several long distance 5-7000 mile cross country trips were included in that. This last tankful was all local driving with city stop & go and idle time included.(but far fewer jackrabbit starts than the first tankful with the lighter wheels had... The kid with a new toy syndrome because the Jeep really does feels more "lively" now )
At this rate I could hope the wheels just might pay for themselves within a decade ! In the meantime the 215 65 16 Continental eco plus are quieter and grip very well on wet roads plus I can supposedly look to get at least 20,000+ more miles on them than I did on the stock goodyears.

And this is the info I was looking for :)
Do you have A/C?

AC was on about half the time...Springtime in Erie means heater on, AC on heater on, AC...

How much does the stock 2011 17'' rim weigh?

You got the 2.0 or the 2.4? Im averaging 31+ via fuelly with bigger, heavier tires and a lift kit with my 2.4 5 speed

2.4 5 speed.

I have 56,000 on mine, average 28mpg nearly every week. Mostly in town with a little 55mph or less driving, if I take it on the road and stay 65mph or less I get 32-34mpg (Interstate only). Took a trip last week and drove 100 miles to local town and then the next day drove 230 miles to another town on one tank of gas, 32mpg average.

I just change the oil when the computer tells me to, I add Lucas upper cylinder/injector cleaner or Marvelous Mystery Oil to gas at that time.

The most trouble free Chrysler I've owned, and I have been driving Chrysler products since 1984.

My wife has a 2009 Dodge Avenger, 2.4 engine. We get 31 MPG on a trip with the trunk loaded. If my Patriot will match that I'll be very content. I'll let you know this summer when we vacation in Canada. :)

I rented an Avenger for a trip to Florida the year before I got the Jeep, just remember the Avenger is slightly more aerodynamic than the basic brick on wheels that is a Patriot. :)

i just bought an 08 5spd 4x2 i'm getting around 32 mpgs while my girlfriend's 2008 4x4 auto is only getting around 27/28...i love the gas mileage!!! everything about the vehicle is perfect!!
