Thats the main reason for keeping some gas in the mags if your not using them for extended periods.
That won't help at all with the primary o-ring that is inside the mag that will dry out eventually. Silicone oil will only lube the valves.

Keep some gas in your mag, just enough to keep pressure on your primary o-ring in the bottom of the mag.
