Don't even think about it. A light oil like that is going to evaporate and haze up your lenses. Then you'll have to take it apart for a proper cleaning. So why not do that now? The grease has probably dried out. It's not worth paying to get CLA'd so open it up and clean everything out then relube it. Get some decent lube and you'll be set.
