onan marquis 5500 generator
Another member has informed me of what oil to use (Mobil 1 10-40), the appropriate oil filter wrench (0420-0577) and the oil filter (Onan 122-0836, NAPA 7398, WIX 57398).
What is the fram oil filter cross reference for onan oil filter 1220893
I use straight 30 weight. Depending on the oil pan. 6 quarts is normal.
onan means oil natural air natural which means the oil is natural possible thin vegi oil and the cooling is done by natural air passing
That engine holds 1.75 quarts with filter change.
The FRAM PH3614 is the oil fiter that cross references with the Onan 122-088 that was installed in the unit. It is half as long as the Onan 122-0800 that is recommended by Onan and actually removed from the engine for replacement. The way the engine cowling is bullt, that means that the oil filter cannot be screwed in or removed because it wsill set too deep in the cavity to get fingers or an oil filter wrench into it.

Depends on what you have. Could be one quart to fifty gallons.
