And then I did an oil and filter change on the Onan genset. I bought the oil and filter at Orielys auto parts. But the filter that was called for was kindo od short so I traded it for a 3600 filter. I guesss Fram makes a PH3600 but the Microguard 3600 is the same size. And this genset had a NAPA Gold 1762 on it. But since the filter is recessed it would be hard to tighten or remove without a different kind of filter wrench.
There was a bolt missing from the bottom of the genset. Just another thing on the to do list.
