I would look at this guy's thread:

I believe there was a speed vs mpg chart made for a pilot, having trouble finding it.
Edit: Nope, it was a ridgeline:

A useful driving technique tip from the thread.
"My 04 Odyssey 3.5 V6 is a 5-speed auto. I'm almost positive this is the same.
My results match, especially the dip at 43 mph. The shift points are 10, 20, 30, and 45 mph. See that last one? It doesn't match. The 40-45 mph span is just painful as the engine revs but won't shift. I generally try to keep it below 40 or above 45.
You can do a quick D-N-D shift and get it to shift sooner, down to about 42 mph."
With SUVs there is a lot of tire area exposed, decent improvements can be had by directing that air away slowly and smoothly rather than smacking into the tires. There isn't much overhang for the front tires, so not much room to make deflectors, but there should be plenty of room in the rear.
This is what I did for my accord:
