    My last motorcycle I got 125,000 miles on it before I sold it never used a drop of oil. One time out in the desert I forgot to tighten the drain plug on my wife's squad. She went about 5 miles before the quad stopped. Put a new drain plug in build it back up with Amazon and it ran without missing a beat for several years sold.
    Bottom Line

    Yes, I would recommend this to a friend.
