i never heard can't go over 55mph, but i certainly wouldn't try going over 80 for 500 miles or so.

the new cars you don't change the oil after 1,000 miles, you leave it in for 5K or so. the honda manual says what to do about that.

it's mainly don't rev the piss out of the motor, i wouldn't bring it past 5,000 rpm till broken in.
