What it gives

Drain interval	Changes / year	Annual cost	Savings	Paid back in

The calculation assumes one paper insert replaced at every change and keeps your current filters: the centrifuge adds to the full-flow filter, it does not replace it. The savings come from the oil, the labour, the disposal and the filters you no longer change as often.
