I don't really feel like getting into anothe debate but those numbers seem way high. My sisters 07 Cobalt SS (2.4L non s/c'ed) Gets 34 mpg at 55 mph. I drove the whole from LI to my house in CT at 55 due to traffic (it was flowing nicely just slow) and got 34 mpg. You get 28 with a heavy QC dakota with a 4.7L... Just not adding up.

 

When we had a 04 jeep grand cherokee with the 4.7 the all time best we ever saw out of it was 21mpg. The numbers to me dont seem right either.

 

why are people braging about the milage there getting.
if your getting poor milage something little is dirty/clogged or it's just that you bought a powerfull TRUCK. not a prius.

and if you get decent milage then +1. but for trucks, gas milage
should be bottom of the list.

 

haha I've been doing ALOT of highway driving in the past 4 months. I drive around 1 am on the highway doing 55 the whole way(cruise Control) and average high 15s..I'm excited about it though..lol

 

Well i can say i used to get 19-23 in my 96 club cab with the 3.9 and 2wd of coarse and i was always hard on throttle and always calculated it by the odo and fuel consumed... and if i loaded that poor bitch down and was hard on throttle i would see 17 worst

 

Weight has almost nothing to do with gas mileage at highway speeds. I don't doubt you only got 34 with that car, you were probably running E10 and that car is geared for speed.

Do you actually read what I post? I said that I am comparing the differences, not the actual mileage. I don't want you to reply to this thread again, unless it's a question or a test that I need to run. If it's not one of those, it's falling on deaf ears.

 

Yes I read it and I understand that you aren't going for the numbers, but that pretty much renders this whole thing pointless. If you can't use the numbers basically all you are saying is that you do better at 55 then 65 then 75 respectively... no kidding, anyone could tell us that.

And weight does have a lot to do with highway speeds if there is any sort or an incline. And although you would think it's geared for speed it isn't really. It only runs around 23-2400 at 70 where as my truck with 3:55s runs at 2000... so that is not a huge difference, especially considering the type of engine.


Really if you can't use the numbers then this whole thread is useless. Yeah you get better mpg at 55... no freakin way...

 

bpark - I think you and everyone else over looked his first post.. Which shows why he is getting these high numbers..

We all know that the over head is going to say its getting a lot better then it actually is.


There's no need for getting upset with other and their opinions

 

Thank you.

 

do us all a favor and use the ****ing odometer.
