Oil Change or addition for Mango furler gearbox


I would like to add oil to the gear box the fib furler on my Mango
#62. I don't have any documentation. Does anyone have experience
and/or documentation for this? I'm guessing that I can just add 90W
gear oil, but the existing oil almost looks like grease and maybe
should be changed.
