Hello,

Last two years going from Denver to Ski villages I have increased mileage over the flatland travel. This year did not even use 1/4 tank from Denver to Steamboat. I live in the St. Louis area and we tend to exceed 80mph on the ride out hwy 70. The only thing I can think of is the reduction in speed, but I'm not sure if that can account for the dramatic difference. Anyone else notice this?

Higher elevation = less air resistance. All driving conditions being the same you will see an increase in mileage at higher elevations.

I haven't ran my Dodge "empty" in the mountains much, most of the miles have been pulling my 5er, but I used to notice this when I had my powerstroke. I could understand it if it was just on the trip home and it was mostly downhill, but it would get better mileage going to the ski lodges also.

There is a dramatic increase in mileage going from 80 MPH to 65 MPH. I drove the night time speed limit of 65 MPH compared to the day time limit of 80 MPH. I saved about 1/4 tank on a 590 mile trip.

My best fuel economy is @ 58 - 60 mph. Over 65 mph the fuel economy drops off fast empty or towing a 8,000lb travel trailer.
