But those attempts were in ideal summer circumstances, distances from 200 to 350 miles and always measured in one direction, slightly declining.
Tomorrow I have to go back, forth and a little detour for 80 miles, where I usually get ~61 MPG (63,6 MPG with only a closed grill). So it will be a challenge, considering that I will maintain speed limits and not less than 60 MPH on highways.
Mods so far:
- grill block
- tires at 40 psi
- wiper delete
- side mirror folded in
- Removed an incredible 112 pounds  of exces weight (2 child seats, spare wheel, tools and all kind of stuff)
- I also closed the alloy rims with strong tape to see if it has really effect. If it turns out to be effective, the next step could be proper closed hubcap/rims. |
That is a good set of mods. I suspect it won't be too hard to hit 70 mpg. Keep us posted.

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.
