Maybe it's worth adding a few more details.
Some instruments, mainly cheap ones (and saxophones more than others), use a type of grease that over time becomes gummy and causes friction, sometimes to the point that keys don't move reliably anymore. Obviously using this type of grease for anything isn't a good idea.
I have about five types of grease, but only one or two for woodwinds. They (or any of the others for that matter) don't become sticky in that way.
I use a relatively thin grease (and/or very thick oil) for pivot screws because of the much smaller contact area. This works much better at lubricating this type of hinge compared with regular key oil. Both the grease and the thick oil are usually too thick for regular rod screw keys because of the larger contact area, though this can depend on the specific key.
It's fine to just use the same oil for all keys, but why not use the best type of lubricant depending on the type of hinge if possible?
As far as smell, neither the oil or grease I use stink or have any particularly strong smell. I dismissed one type of oil (which used to be recommended here occasionally) because of the strong bad smell (plus it was too thin).
