Watch oil - http://www.ofrei.com/page246.html It will be an absolute waste to use this oil on anything you haven't cleaned - and by cleaned, I mean disassemble, brush with solvent, zap it in the ultrasonic. Oil only works as it should on clean surfaces.
For your purposes, use something like "Break Free" or "TriFlow" and consider what you are doing as a temporary (very temporary, for evaluative purposes only) measure at best.
The trouble with oiling contaminated/dirty mechanisms is that the oil you apply mixes with the dirt, spreading it everywhere, and causing greatly accelerated wear if any abrasive particles are present. You may also be creating more work for whomever does the CLA. The two products I mentioned are intended for use on dirty mechanisms, but they are not a substitute for cleaning.
Do NOT use WD 40, it dries to a waxy residue that is very difficult to remove. 3-in-1 oil sucks too.
