What's your best 25, 50 and 400 mile MPG?

[DennisT]

I was playing with the mileage meter in my Denali and was surprised at the best mileage numbers. They must occur when going down a mountain.

My bests are:

25 mile - 25.9 mpg
50 mile - 24.5 mpg
400 mile - 20.8 mpg

What are your best numbers?

I have a 33.3 fifty mile avg.
I couldn't believe it when I pulled in for gas. Did the math by hand and on that tank I believe it was 29 mpg. I didn't write it down but my dash still shows 33.3!

2016 Tahoe has been incredible. 29.7 MPG/25 mile average; 29.3/50 mile average. Sweet spot was at 68 MPH on a late spring day. It was still climbing, but I ran out of interstate. I get 25.5 MPG day in and day out on the interstate.
