Does the M Graham Walnut Alkyd Medium go rancid if not stored in a fridge when not in use? - mark graham meades

I read on the website painting.about.com;

"Painter's Handbook1 Mark Gottsegen said that walnut oil is not yellow and dries a little faster than oils of safflower and poppy seeds. He warned that" not so many nut oils "walnut oil is not good and, unless refrigerated rancid.

This appointment is for the walnut oil, and not necessarily that of the walnut alkyd.

Thank you very much.
