From info posted by various people here, it seems to be important for best mpg to:
- use OEM spark plugs, and to match them to the letter stamped next to the spark plug hole on the cylinder head so the electrodes are indexed correctly
- use OEM Bridgestone RE92 tires (anything else seems to cause a 5-10mpg drop in back-to-back testing) and pump them up to at least 44psi (the sidewall rating), preferably more
- use 0W-20 synthetic oil
- use the Honda MT fluid spec'd for the transmission
Yes rain makes a huge difference, probably in tire drag. I move laterally in the lane to try to stay away from the deeper standing water but it isn't always possible.
But it sounds like you're getting there!!
