Upon getting my first 40 mpg, I ended up getting 3 in a row and it was combined not highway in which it was achieved. The ave speed for those tanks was in the mid 30 mph range.

My 'in town' tanks usually net 30 mph ave, along with a 36 mpg ave.

My combined usually averaged 35-38 mph to give a 40 mpg ave.

My highway ave was 45+ mph and usually netted 40 mpg, or very small difference vs combined. (This was with driving slower than the PSL on interstates).

Now, I have slowed down more in the city and increased my speed on the interstate (to take advantage of the corridor effect and partial draft).

On a record tank now and the majority of miles/time is highway but it's looking like a 42+ mpg tank. Showing 600 miles on this tank with 1/4 left.

I use to struggle to get 36-38 on a highway tank (too much cruise) and now seems much easier to get better. Here's the interesting thing, when going uphills on cruise, my UG will give me the same instant MPG reading doing 55 or 70 mph, the only difference is the GPH.

Oh, the SRT feature on the UG has helped a great deal.
