Well it matters if you service your machine regularly and with the good oil........and it will last that bit longer than someone who runs it into the ground!:ashamed:
Also along with good oil... Change it completely at LEAST once a year.
I have known folks that have has engine failure tell me that they don't know why they have problems with small engines... they always check the oil and add some when it is low.... but usually when asked how often they drained it, to tut in fresh ... never...
If you want to keep it dependable, you have to do your part to keep it that way... :smile:KennyV
