The Adventurer came with an Onan 5500 watt HGJAB generator. 15W-40 oil is recommended for temps 10*F to 100*F. You can use 30W iol if you are in areas where temps don't go below 32*F. For temps 0*F to 80*F you can use either 10W-30 or 10W-40. For temps of -20*F to 50*F 5W-30 is recommended.
All these specs are available from the operators manual available from the Cummins site at:

They also have parts, service, and installation manuals. I have all of them, but the service manuals aren't of much use to the average consumer unless you have the recommended special tools. Several of the diagnostic trees rely on use of special tools. They assume the manuals will be used by people with those tools so they don't give many details on how to make problem diagnosis without them
