Here's 6th gear at 70. I have the 3.73's with 275 tires on 18" wheels.
The lie-o-meter displays 16mpg!! Makes me smile. That's about 80 miles into my 200 mile round trip with a little tail wind. By the time I pulled in my driveway it said 15.4mpg. I was averaging 75 mph. As you can see I only have 4K on it and the more miles I rack up the better the mpg's get.
