FWIW - In the reliable hubs on mine, I've run both the 50W motor oil and 80-90W gear oil with no difference. Filled up the hub about 3/4 full, but my axle is not pressurized with the spring set up like the one you posted. I can understand why they'd maybe want you to fill that one up completely to avoid water intrusion.
