Singer 411G - Oil? Grease?

Quick post. Just picked up a 411G (so thrilled!). It was pretty noisy, so I went around with a few drops of oil here and there (I've been following sewing machine repair, so I think I did okay. But here's the question(s):

I'm using oil that I have on hand for oiling clocks. I'm assuming that is appropriate for sewing machines. Is it? I don't want my 411G running fast or slow. /s

AndyTube mentioned NOT using oil on gears. Well, shucks. I oiled the gears, including where the motor meets the other thingy. Is this bad? Grease? If so, which?

Thanks! I really want to take the best care of this guy.
