I just finished a hand calculated test and am getting 8 mpg. That is all local driving the past 2 weeks. I got 173 miles to the tank. I filled up 21 gallons. This is awful. Does this make sense, or can something be wrong with the performance of my vehicle?

I think the problem is solved. It is the gas station I HAVE been getting gas from all the time.[sm=bustedsign.gif] I switched over the weekend and guess what? I am getting 15 city and 19 highway again. I was supposed to go to dealer today but called to cancel and they explained to me that the station's pump clocks are off. They are pumping mostly fumes instead of liquid. The fumes fill the tanklike airpressure making your guage appear to be full but in turn the fumes burn faster than the liquid. [sm=WTFsgign.gif]

I will continue to use NEW gas station and let everyone know how I am making out.


Hey there. This is now the secod time I have had to write about this. I thought I had it figured out before but I guess not. I am now getting between 6.5 and 10mpg local driving and 17-19mpg on the highway. I am satisfied with the highway mileage but what gives with the local driving. We are supposed to get 15mpg local. I understnad that is under optimal driving conditions and I don't expect that but why the heck am I getting only 6.5mpg at times. I don't floor it, stand still too long (only redlights), maintain my speed. What gives? What is everyone else getting with their Aspens? I am from Bayside, NY so I would be interested in hearing from those of you from a city setting what you get loacally. Thanks for any feedback.

 

Joe,
I think your issue may be not getting the tank completely full each time you measure. You need to use the same pump at the same station and use the same cut-off proceedure, ie full tank.

Our 2007 Hemi Aspen is very conistant in town at 14.4 - 14.8 mpg and on the highway 22.4 to 24.3 mpg. We check with the DIC as well as hand calculating the fuel mileage. When a number is way out of line is due to not getting the tank full.

We love our Aspen and its mileage.

 

Hi Jim, I am definetly filling tank to the top. I always top off at the pump. I used to get the same mileage as you but I am not now. I have just over 13,000 miles. On the highway I still get decent mileage of 17-19mpg at 65mph and the rpm's below 2,000. It is just local driving that has become dismal. I noticed I barely step on gas pedal and my aspen can do a whole NYC block. I think it is something to do with the injectors putting too much fuel possibly. I think I need to get it checked out at the dealer. Thanks for your suggestion.

By the way, I LOVE the Aspen. The best vehicle I have ever owned. Just have to figure out the gas mileage.

 

I had a chance to have the Aspen on the highway for 2000km trip. Fuel economy was pretty decent. I got somewhere between 25 mpg and 26 mpg.

 

10,000 miles on my 2008 aspen with the hemi 19 mpg on the highway, i can only dream of ever getting 25-26 mpg. on the highway. that is real good miliage for the size of the aspen. that is about what our car gets with a v/6 engine. a lot of carsdont get that kinda miliage.

 

I might add my cruising speed was around 65mph, A/C on the whole time as well. I too find that the economy of this is better than most V6's, whether it's an import or domestic. Our Honda Odysseys best fuel economy was around 24mpg, hauling the same people, probably close to the same weight of vehicle too. So all in all I am likin' this Aspen, not to mention, you put your foot down and you are g o n e .

 

OK guys I just got 2007 Aspen with 28,000 milles a month a go and I was geting 12.4 mpg i nthe city I haven't been in hwy yet a. But I find it toomuch becasue I have a company truck Ford 250 and my average is 14.4 is that crazy my friend has a 2007 Silverado 1500 and he is getting 14. mpg so I dont know what to do.
I got one of thosse performance module that ou install inteh ATS senson and now is averaginf 13.5 -14.2 MPG in teh city tool in 30 miles from here in the freeway and I got 15.6 so I will keep trying this holiday weekend.


Any other sugestions??????

 

good luck hope you have one of the aspens that gets 24 and 26 mpg on the highway,there are only a few that gets that kinda milliage. maybe you have one of them,

 

OK. I am lost. I filled up at yet another new gas station in my neighborhood. This one happens to be the cheapest gas in the area too ($3.83/gal). I nearly dropped dead when I was getting 17.7 local and wait get this, 25.5 highway. What the hell are gas stations doing that there is such a difference in the mileage we get.So far on a quarter of a tank I have gotten 125 miles. This is amazingly better than just last week when I was getting 6.5 mpg local and 17mpg hwy.

 

i dont know what to tell you, i know if i ever find a station like that i will have the station put my name on the pump , that way i will have my own personal pump.
