When installing new cables and housing, is is wise to oil the housing?

If so, how? Here Hicks recommends spraying (but for re-newing old cables). On the other hand, I have found it intuitive to put a drop of oil onto the entrance of the housing, then thread the cable through it.

My rationale is that oil reduces friction, and cables and housings enjoy lack of friction.

So does oiling new housing help, or is it reserved for servicing old housing systems?

I would suggest leaving new cable housings as they are. From my experience with riding MTB bikes in different conditions, lubing them only attracts more dust. I suggest regular cleaning and using oil only for short term reviving. These cables need to be replaced once in a while anyway.

How can you know how much dirt enter inside your cable housing? In the first place, how can dirt enter inside the nearly sealed housing? –  Vorac Oct 28 '13 at 15:59

@Vorac: when you remove the cable and it is black and sticky, then this is a mix of dirt+oil+time. –  cherouvim Oct 28 '13 at 19:18

No, you shouldn't apply to additional lube to new cables and housing. These come pre-coated (cables) and pre-greased (outers) so adding anything additional is not required and could possibly degrade the factory lube.

I did never see pre-coated cables. About grease in outers I'm not so sure. –  Alexander Oct 28 '13 at 20:29

Simply look at inners in many online stores they have low friction coatings and in the case of top quality cables like Jagwire have a Teflon coating. Similar with outers, these have ptfe low friction centres and come pre-greased with low friction silicon lubricants. Unless you are bying the cheapest cable and outer you can find your unlikely to buy something untreated or unlubricated. –  DWGKNZ Oct 28 '13 at 20:56
    
I am actually buying the cheapest cable and housing :D –  Vorac Oct 29 '13 at 7:34
    
Don't know. I leave in Israel, and didn't notice of coating on cables. The outers come with Teflon coating and I see it as enough for our climate. –  Alexander Oct 31 '13 at 21:51
