Gen oil filter
I have a Onan 5.5 Gen and I just checked the last time I changed oil! It has been a year and 8 months and 14 hours! Should I still change oil and filter with that few of hours ??

I use the full synthetic oil in mine. I stay with Onan's schedule, but the synthetic oil for more peace of mind. Plus it starts much easier in the cold weather.
