Well I will try oil but it's not for every shave just when I have to shave 2-3 days in a row. most of the time it's every other day or maybe even every 3 day. I'm retired now and where I live looking presentable is not required. Heck if I'm out side and have to go well I just walk up to the nearest tree and raise one leg. but now and then we go to town and movies and the like so I do have to look like a human.
