Most mower engines are 2-strokes, they’re designed to burn oil as lubrication basically, it’s added to the gas. You don’t need to change the oil. Unless it’s a 4 stroke engine (unusual due to size/complexity), or you’ve got a transmission or some other motorized mechanical behavior.

Most mower engines are absolutely not 2 strokes… they are 99.99% 4 strokes.
Now strim trimmers are maybe 60/40 2s to 4s.
As a 2-stroke myself, I can confirm oil for lubrication is not required
