I don't know what's inside, but I have added heavy gear oil (85w-140?) previously to whatever as been residing in there since I bought it.
I am avoiding synthetics, because I too have heard of their tendency to leak.
FSM recommends 50W or 80W-90, 30W for subfreezing, 140W for 90 degree+ weather.
Thanks
