There are a lot of posts in this board related to Onans and their problems, not so much about Kohlers (although it appears they were OEM on some GMCs). I haven't fired it up yet, but...
The manual says that the minimum octane rating for it is 90. Since it will use fuel from the same source as the 455, and I had not considered feeding the 455 anything other than 87 octane, what consequences should I expect? Early demise of the generator? Degraded performance (inability to run both rooftop ACs)? Any Kohler owners out there that can speak from experience?
