I don't shave with a straight yet, but I do use a pre-shave oil (when I have it) and I notice a huge difference. I don't know if it's a much closer shave, but I do get a lot less burn and my skin feels much smoother (not as angry) than w/o the shave oil. I also like to put on after my shave is over with, it helps to sooth what burn I do get. I'm no shaving pro, but thats what works for me.
