What oil do you use for a mini chopper?

For a mini chopper, it's best to use a food-safe oil like vegetable oil, canola oil, or olive oil, as they are suitable for cooking and won't impart unwanted flavors. If you're using the chopper for non-food purposes, such as for woodworking or other crafts, consider using a light machine oil or mineral oil. Always check the manufacturer's recommendations for specific guidance on oil types.
