Most Onans that I have seen have the points box on the top of the engine.
Still not always convenient, but at least you don't need to dismantle the
engine. The manual for my CCK (no oil filter) specifies 100 hours. That
might sound like a lot, but it would be the same as several thousand miles
in an auto engine.

Actually, it doesn't really sound like a lot to me. I am guilty of pushing
the limits on some cheap engines as far as oil changes go. I used the
change the oil on my Chinese 2000 watt genny every 50 hours, as recommended.
It has about 3000 hours on it now and I've been changing the oil about every
100 hours (or slightly more) for about the last 1000 hours. At 100 hours
the oil is still transparent and not very dark. Looking at the oil may not
be the best way to determine when to change the oil but it seems to be
working for me. OTOH on a Briggs I might change the oil after only 25 hours
because it'll look black and yucky by then.

The cheap oil gets loose and runny. Loses the viscosity
protection. Please use good brand of oil. Castrol is my

Maintainance is the key to longevity on ANY Mechanical Device. Having a
Pressure Lubeoil and Filter System increases the Oil change Period form
50-100 Hours, to 200 Hours, or once a Year, which ever comes first, on
the Onan Engines, and MOST other 4 Cycle Gasoline Fueled ICE's.
Converting to Dry Gas Fuel can increase that to maybe 300 Hours, BUT,
remember that LubeOil, is the cheapest Insurance MOney can Buy....
Very Few of the classic Opposed Twin Onans are Magneto Ignition, so in
most cases, the Points are located on the top of the Engine near the
Carb. This class of Onan Gensets are KNOWN for their reliability, and
long Lifetimes, (10K Operational Hours) IF the OEM Periodic Maintainance
is done. The problems come when some owners just think they can store
them away, for years, sometimes, and then drag them out, blow the dust
off, and expect them to start and run, 24/7/Days or Weeks with no
issues.... That expectation, is just plain stupid, for ANY ICE, not
just Onans. If you can't, or don't, do the Periodic Maintainance, don't
expect to have power, when the Grid goes down..... and that classes you
as a "FlatLander".... "City Boy" for you Red Neck Types....

It sounds to me like the Onans have many advantages and few disadvantages.
I may be needing something in the 5K range in the near future so thanks for
all the info.
