Are you quite sure your seals are SILICON? I've never known Silicon seals fitted to any airgun as they aren't usually up to the job, but there's always a first
Replacement seals are usually NBR or Pur (polyurethane)
Just put a little silicon "Oil" between your fingers & rub each seal with it, the seal should only glisten not be wet if you see what I mean, that's enough! Too much lubricant can stop the valve opening properly & will cause inconsistency between shots.
Metal to metal stressed or moving parts can have a small amount of moly grease on them & the felt on the piston (if fitted) can have a tiny amount of light machine oil on it.
The key is....... little is more!
IF IT'S NOT BROKE.........DON'T FIX IT!
