How to maintain a lawn mower?

Michael Patton
by Michael Patton

This might be a little off topic but I recently bought a used lawn mower without manual and am looking for tips about how to maintain it such as how to change oil and how often and what type of oil to use, how long can I let gas sit in the mower and should I add fuel stabilizers to the gas, and anything else needed for lawn mower maintenance. Thank you.
