damn i must have a lead foot cause i only get like 12-13 MPG. i guess i have to take into account that i remote start my tahoe alot now since its like 20 - 30 degrees every morning in jersey and by doing that i just watch the MPG drop.

 

I drive to school about 3 days a week... 75 miles each way... so about 450 miles/week highway. And i drive about 200 miles city driving per week. I have almost 17,000 miles in 7 months. With 17" rims i average 17.6 mpg. That's way better than my old durango

 

Before our cold snap, was getting about 13 (calculated) and then put in Mobil 1 and it jumped to 13.5. But then with the cold, it really dropped, especially if I remote start to thaw out.

I've never seen V4 on flat roads at highway speeds.

 

average 16.7 mpg

 

I get 16.5 in town. Got 19.5 driving to Miami one weekend.

 

I'm getting around 17 to 18 mpg but i drive 90% highway. I use cruise alot and it almost never goes into V4 mode. If I cancel the cruise or if i'm going downhill is the only way it switches to V4. I'm running stock 17's but looking to upgrade to stock 20's. From what I'm reading, i guess when i upgrade i can expect to see the mpg drop.

 

The wheel size makes a huge difference. Mine came with factory 17's. I averaged the same, 17-18. Even got 20MPH on a 400 mile HWY trip.

Then I upgraded to 20's. I averaged around 16-17.

Now with 24's, I havent averaged above 15.

 

I avg about 13.7 highway/city. I do have 20's nitto all terrain, air raid, magnaflow exhaust, 4.10 gears....oh yeah and a HEAVY FOOT. I do reset the MPG now and then to see, so sometimes I will get 15 when I am nice.
