Use create when you are creating a new item.
Use save when you are making changes to an existing item.
It's clear from the language that 'create' is a new item of some sort, and succinctly communicates that what you are about to do will result in a new record being created, but that if you don't, that record will not exist.
Similarly, when using 'save', it is clear that if you were to cancel the operation, the record will still exist, but any changes you have made will not exist.
Any deviation from these standards will likely result in confusion as your actions and the description of them are misaligned.
