Okay, new forum for me. Found myself in charge of my church's property committee. We have a small natural gas powered Onan emergency generator that we're supposed to run for 1 hour a week. No manual or anything that says what oil it takes and June is when we change it (annually). There is a bottle of Pennzoil 10w-30 in the room so I assume that's what's in it. Also it has a Fram PH16 filter.
Is any good 10w-30 okay? I'll cross-reference and get a different filter.
Thanks.
Thanks.
