Because I was using the alternator all of the time last tank, I slipped a bit (to under 65mpg) because I am no longer willing to drive slower than posted speed limits. But I have a better strategy about the alt now. I cut the alt under three conditions now: on the freeway, during the last two miles of my commute home where I plug in, and while climbing unavoidable mile-long steep hills when the speed limit is over 40mph. Under those conditions the ECU always puts the alt at max output, so cutting it and then regenerating down the opposite side with DFCO seems like a good strategy.

I also returned the tires to 60psi (they had slipped to 55). I could feel the difference.

But right now I am not as focused on the car because I am researching split system air source heat pumps for a new heating/cooling system in my house. ..but I do have my list of car mods...

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.
