I don't know what is wrong with the computer. They do not get sticky from lack of oil they get rusty. The sticky is from dried oil. If it were oiled the sticky might loosen up a little. Some oil works faster to dissolve than others. Heat will help loosen up the old dried oil but it may re-sticky when it cools off. If someone used an oil like 3 in 1 oil it may be hard to get unsticky. I would use some tri-flo on every moving part. Turn the hand wheel and look to see what moves then give it a little drop of oil. You don't need to baptize it.
