I understand that it's not advisable to fill it with oil,  due
to the motor being mounted in a vertical position. Is that
an  advisable thing to do?


    Sure. The thing only runs at 3/4 RPM or so  intermittently so a lot of 
guys run them without oil. And yes, oil will seep  thru the gasket. It's not an 
issue when they're installed in their normal  horizontal orientation when 
mounted on the airplane.
