for both? a half a pint, maybe.. but at least with linseed oil, (a great choice, imo) you can re-apply anytime. Actually you'll probably need to re-apply once a year at least. It will darken it slightly, but it will make it look richer, and more wonderful first.
+1. Widely available and cheaper than mineral. Shit, I'm surprised you didn't rub used motor oil on them. Do both sides
