I have enjoyed my 'new to me' AC720; need to change oils. What do I use:

air cooled Onan engine?

hydrostat?

dropped rear axle?

hydraulic lift?

-I use sae30wt in my Onan CCKB with a Purolator L20195 filter.
-I use cheap Rural King brand Dex/Merc (by the gallon jug) in the hydrostat with a Napa/WIX 51085 filter, but you could use Type F transmission fluid as well.
-I use straight 90wt gear oil in the drop boxes.

The hydrostat, lift system, and transmission all share the same oil.
