This goes for all locks, oil may appear to improve things in the short term, but over time oil binds with dust and any other loose particles and will stop the pins from moving freely. That's as bad for picking as for regular use with a key.
OIL+LOCK=PROBLEMSUse graphite powder (if you haven't any,you can make your own by finely grinding the lead of a pencil with a sharpener, just be careful not to include any wood shavings! You don't need much)
I would
not advise using graphite from pencils. You are quite correct that the 'lead' in todays pencils does is in fact graphite, but there is also a substantial amount of clay in it, to serve as a hardener. This also allows for the different hardness pencils, by changing the ratio of graphite to clay. Clay is abrasive - and abrasives do not belong inside locks.
It shouldn't be too hard to find real graphite powder. Any hardware store should have it in little 'puffer' bottles/tubes. Places which offer key-cutting services often sell it too. Artist supply shops should also sell pure graphite 'sticks' or crayons. That would be a much safer than pencils for those who cannot simply buy pure graphite powder.
There does seem to be some controversy with respect to using graphite in locks - some lockies swear by it, others advise against using it.
If you are going to use graphite, you only need apply TINY amount. I am sure some problems with graphite result from people simply using too much.
Another problem which can arise is when graphite comes into contact with a lock already lubricated with something else (specifically greases & oils) - the graphite plus the oil makes a nice mud to gum up the lock.
If you flush out and clean a lock thoroughly, to remove any other lubricants/greases/oils(brake cleaner would be a good start), and then apply a little graphite you will have no problems.
As far as WD40 goes, it is NOT to be used as a lock lubricant. It can be useful to free up a really jammed up lock, but it is then essential to flush out any residual WD40, followed by applying a suitable lubricant.
My own preference in most situations is tri-flow or other silicon lubes.
