I use a brand of pre-shave oil that is called shave secret. I pick it up at Walmart for less than $2.00 for a 18.75 ml bottle. I only use 3 drops so it lasts about a month. I smells good and really works. It has all natural oils and has menthol and cloves in it. If you don't have a Walmart near you you can get it on line at Shave Secret shaving oil provides the most comfortable, smooth shave ever! but it costs more than Walmart.
