Strange that at 50-55 I get 6 to 6 1/2 mpg at 59 to 61 I get 7 to 7 1/2. So your graph is full of it.

not necessarly:
As per a previous post;;
different gearing makes a difference; most folks will get a better milage at 55 MPH

I don't know what vehicle that graph was made for, but I haven't seen 30 mpg on my coach, or my other vehicles for that matter. For the chart to be relevant is would have to be of the type vehicle and motor under discussion.

At 58 mph my motor home changes from 5th to 6th gear. Mileage is much better at 60mph than below 58mph but does decline as the speed increases above 62mph depending on the wind resistance. I use Silverleaf software to monitor my mpg and have improved my avg. mpg from 7.7mpg to 8.3mpg. When the speed limit was previously changed to 55mph many truckers complained because it forced them to drive in a lower gear reducing their mpg.

To get better mileage'
The wind is not your friend

I dunno - I've found that a 50 MPH tailwind helps a lot!

yes but---
I was in Montana with a 30 MPH headwind----gas mileage was 4 MPG

Today, an American Tradition passed as we were going east of 54 between Jeff City and Fulton. He was in a big hurry and made 70 look like we were very slow. There was a problem. He had not secured the window awning on the left rear window and it was whipping in the wind and looked as if it could be ripped pretty badly.

Probably had those shiny things up by the windshield pointed so he could admire himself.

I cruise at 60mph, and stay in the right lane as much as possible. If someone wants to go faster they can and do pass me in the left lane. If someone wants to go slower I can and do pass them in the left lane. I don't get upset with them, I hope they don't get upset with me. I have checked and do get better mileage at 60mph than at any speed faster or slower than about 2mph more either way. I'm still working so only have limited time to get to where I'm going. If I could get the same mileage going faster I would. I don't believe speed is a safety factor so much as being awake and paying attention. If you can afford the cost of fuel to go faster- I say go for it.
