Use a high quality light clock or watch oil, the modern synthetic oils will last for quite a few years and oils suitable for cold weather are available. But, putting oil on without cleaning the lubrication points is pointless, the new oil will be contaminated by the remains of the old oil and any dirt/abrasive contamination, also it will probably creep away leaving the parts dry. A couple watchmakers oilers can be had for $10 or less; putting too much oil on is as almost bad as none. Some points require only the slightest dot of oil (get a 2.5 - 5x loupe so you can actually see how much you apply) and other parts must be left dry. Gear teeth are typically left dry - there is no sliding contact between well cut teeth, and in a camera no inertial loads (resulting from high rotative speeds) that need cushioning by a lubricant film. Use a light grease on the gear pivot points.
