I made a preshave oil with castor oil (2 parts) and sweet almond (1 part), scented with peppermint EO.
I had the same impression as you, that it was giving me some extra protection and a bit of extra glide. I used it for a week solid last week, this week is a no-oil week. I'm still getting pretty awesome shaves so I'm not sure if it was the oil or something else about my technique.
