What substitute oil can I use to save me the cost of buying an additional
special oil for my Fellowes cross-cut shredder used in my home office?

3 in 1.

I've got a Fellowes cross cut under the desk in front of me. It is the
only one I've ever bothered to lube and it seems to have surpassed the 2
other (never lubed) ones before it.

Certainly hasn't broken it anyway.
