Since I was 14, I've NEVER lubed a cable.
I even bought one of those little aluminum blocks that go over the cable housing end to help lube one about ten years ago, but never used it.
I've been fortunate I guess, as I've NEVER broke one. I'm guessing that the cables on my '71, '72, '80, and '82 bikes are original. I KNOW I'VE never changed one on them, and, I KNOW the cables on my '99, '03, '04, and '05 have never been lubed OR replaced.
So I'm gonna say "NO".
