It takes very little oil to lubricate an entire tank of propane. I calculate:

tank capacity: 465g
gas used per 1x TM Hicapa mag fill including overflow loss: 8g
total mags filled from one can = 465g / 8g =58 mags

at two drops per 10x mags: 12 drops per can

Whatever you do, do not inject large quantities of air into your tank. Purge your device with propane before using it to displace the 20% fraction of oxygen in air before pushing bubbles of air into your tank.

Be advised that there is no lifecycle data on propane valve sealing surfaces with direct exposure to silicone oil. If your tank valves should leak you could vent an entire tank slowly. Store your tanks outside in a ventilated area.
