I've used it a few times already. I'm approaching the 10 hour break in oil change mark. I am in love with this mower. It's fast, turns on a dime, and really cuts the lawn to perfection. It used to take me 2.5 to 3 hours to cut my lane. I can do it now in less than an hour and 15 minutes. Including the trim and cutting around my preach, apple and cherry trees. I cut just under 2 acres, almost twice with 1 tank of gas. This thing is a BAD BOY!!!
