Lawn Mower Honda GCV170 Oil Change

Lawnmowers need to be maintained to function properly for a long time. In all my years, I have never seen or heard of anyone changing their mower oil. I don't remember my dad ever changing the oil in our mower, and I have never changed the oil in a mower. Of course, I usually get beat up mowers and run them until they're dead, but they probably would have lasted longer if I changed the oil as soon as I got them.
My wife bought me this mower in the video, and I love it. I plan on being able to use this for many years and will be maintaining this on a regular basis. For being as cheap and easy as it is to do an oil change, I don't see any reason to forego them. This doesn't even require any tools on this mower, which makes it that much easier.
