You don't tell us the model number of the Wisconsin engine so I'l say SAE 30 unless it is a newer OHV engine.

Page 71 of this manual give a breakdown of what oil to use in Robin engines. It's not the service manual for you engine, but the type of oil used in the smaller Robin engines does not change.
