Initial Break In Service 

For new engines it is recommended to change the oil and filter after the first ~20 hours of run time. This removes any contaminants or metal particles from the break in process.

Every 100 Hours of Annually

Perform an oil and filter change every 100 hours of operation or once a year, whichever comes first. This interval helps maintain lubrication quality and engine efficiency.
