As noted, the oil only has 8 hours on it but it has been one year since the last change. Given the low capacity (1.6 qts) and the lack of a filter I didn't want to stretch things out. Hopefully it will get more use this year.


The answer to 80% of BITOG questions: Read the book, follow directions.
Changing oil is not maintenance. Maintenance is the science of inspecting equipment to find and fix things before they break.
