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 ??

Yes. The manual for my Onan says to change the oil annually or every 150 hours, whichever comes first. I don't know the rationale, but I intend do it (first change was when I first put it on the road a couple of months ago).
