If you use your shredder occasionally, then oiling your shredder may only be necessary every two months to maintain good performance. If you use your shredder a lot, however, then your best practices are to oil your cross-cut shredder every time you empty the waste bin.

If you don’t oil your shredder regularly you may find that it starts to accumulate paper dust and begins to process fewer sheets of paper at a time and at a slower rate. You may also experience more paper jams.

The answer is no. This product is not designed to lubricate a shredder head properly. Like other oils, such as vegetable or canola, WD-40 would cause the paper to stick together, inevitably gumming up and jamming the machine.
