I’m going to lightly lubricate my used Yamaha 23, as one or two places need a touch, and I’m sure it wouldn’t hurt other mechanisms to have a tiny bit. I see the local music shop sells light, medium, and heavy key oil. My instinct would be to go for light, but that’s based on a wheelbarrow-full of ignorance. Any better informed advice is most welcomed.
