I've tried quite a few different pre-shave oils (sensitive skin and heavy beard here) and an inexpensive mix of extra virgin olive oil and castor oil works just as good as any. I also add essential oils to the mix, but be careful when doing this as some can irritate the skin. I made this mistake with peppermint. It's fine used in other skin conglomerations, but when used as a pre-shave oil, it was pretty irritating and dried my skin out. Counterproductive to say the least.
