Q: Do you really need spare core filters? They are designed to be cleaned and reused.

A: If the cores are intended to be cleaned and not replaced then I would only need at least 2 spares in case of failures.

Q: Graham Burke and Huxtable only have strainers on their oil systems which does not filter the oil.

A: Are you currently using particle filters? If you are do they need to be replaced as well?
