I disconnect the cable , dribble some oil in , then slide the cable
in-n-out to "pump" the oil in . I average lubing them about once a year ,
and always lube them well before installing . My preference is synth gear
lube , it seems to crawl into the cable a bit faster and seems "slicker" .
On some cables I can build a tape cone to act as a reservoir for the lube .
A little less mess and it goes a bit faster .

That is pretty much what I do.
Thanks!
