The oil takes up air space in the shock and acts as a barrier to keep air in,
I just looked at Progressive site and it calls for 2 oz of dextron,
Found this

,bout the only "rebuild" for the 416's is the replacement of the oil seal and oil refilling... The oil seal wouldn't qualify as a littl o-ring, so consider me a +1 for what Dale Sr. posts above...

Sadly, progressive has redesigned their site and made their instructions a bit more difficult to find.

This PDF is the installation (the 2small o-rings are seen at about step #9):

This PDF presents the seal removal and replacement... Generally, when I refill these I'll use 4oz - 6oz of oil for the GL1500 if it's used a lot 2-up, towing, or with a heavy bag load. :
