Highway commuting (even in congested CT) is less stressful on the oil than pure city driving. Especially if you're a moderate driver.
Having the oil changed four times a year for free, (for you, roughly every 4300 miles) using the dealer's 5W-20 regular oil, will be more than enough to make your car last to 200K.
Nonetheless, I'd use Mobil 1, going Honda's full (7,500 mile?) interval :-)
Edit: I calculated the 4,300 miles using 66 miles/day times 5 days/week times 52 weeks, then dividing by 4. Didn't see your "25K/year" statement... that's 6,250 miles/quarter. Go with Mobil 1!
