Blue Dolphin Rain Lamp Dripping Oil Ocean Wave Light Working Retro Decor Vintage

Blue Dolphin Rain Lamp Dripping Oil Ocean Wave Light Working Retro Decor Vintage Preowned oil lamp. Has been cleaned but could probably use a deeper cleaning. Tested with a new light bulb and it does light up (light bulb NOT included). I bought some basic mineral oil (NOT included) and sadly, it didn't seem to be working. I'm not sure if it's because I didn't put enough in, if it needs a new motor, or if the light bulb needs to be a specific kind. My guess is that it needs a new motor. There is also a crack at the top so I don't know if that's a factor (I don't believe so). May be a bit oily, even though I tried cleaning it when I was done testing.
