Drove 445.0mi today, 70.5mpg.
I mostly cruised as fast as lean burn would let me, for 75mpg @ 69mph typical on flatlands, much lower mpg on hills (as I would lean burn down hills at 74mph and pulse up hills at 50mpg). I may have confused a few truckers with my DWL.
Hit rain in Indiana. MPG and MPH both suffered.
I learned a few things about lean burn, boat tails, and the need for MIMA today. But more on that some other day. For now, I'm happy with making good time while getting great gas mileage.
