painting on walls with oil?

Hey everyone, I want to start painting a small mural on a wall at home, but I’m not sure what type of paint is best. I’ve always used oil on canvas, so I’m wondering if oil paint works on walls too or if that’s a bad idea in the long run.

Do you usually stick with acrylics for wall work? Also, is there anything special I should prep the wall with before starting?

Any advice would help a lot.
