My personal best on a single tank for regular commute 75% hwy at 65mph+ traffic is 38mpg. I am guessing if I go on a all highway long trip, I can get over 40 which is what I was expecting.
Long story short, if you are considering a HX/ D16Y5 swap, expect 35mpg and a lot more fun than the D16Y8. Make sure you use the proper wiring to safe time and headache. Good luck!!!
Congrats on loving your ride! Always important. Gotta love what you drive, if you have to drive it a lot. And I'm sure you can squeeze more MPG out of the HX engine when you want. One point of correction: the DX had the D16Y7 engine, and the EX had the D16Y8 that you refer to.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
