Hi Kenny:
___From 59.8 mpg to ~ 62.6 mpg or so appears to be an ~ 4 + % increase which sounds about right. You are doing better then great actually!
___By the way, let me officially welcome you to the “Hyper Mileage Club” as currently occupied by Rick Reese (Insight and Prius I), myself (Insight, Corolla, and MDX), Ericbecky (Insight), Hot_Georgia_2004 (HCH), Gshepherd (Prius II), Jjmcubed (HCH), Buzz70 (HCH), Mrkcohen (HCH), Livvie (HCH), Texashchman (HCH), Videian (HCH), Kabel (HCH), Rpdog (HCH), Jinno (HCH), and Brian Maher (HCH). To belong to this unique but exemplary group of “
characters”

all you need to do is maintain > EPA combined estimates tank over tank over tank. I know quite a few more Insight’ers and I am sure many know even more HCH, Prius I and II, as well as Diesel and SI ICE automobile owners that belong to this club as well but I haven’t seen them post over here just yet? I only hope I didn’t miss anyone given the many real mileage database overrides and actual combined EPA estimates of the non-Hybrid’s listed …
___The official motto? Let me steal a line or two from the
unofficial motto of the US Postal Service …
“
Neither snow nor rain nor heat nor gloom of night stays these Hyper milers from beating EPA estimates on their appointed daily commutes and leisurely drives …”
___I spend entirely too much time on the Internet I think
___Good Luck
