There are many different oils out sold by vendors: John's original mix, Hater Sauce, D1, X1, BB Extreme, and Spacewalker Oil, just to name a few. Most, but not all, are a Krytox based with an additive. Almost every pro uses one of these oils or a combination there of. I do not know of anyone that makes there own from raw materials. That being said, each racer has their own combination of wax and oil they race with. Its not important to know which oil a pro is using, but rather how the oil you select is supposed to be used. In John's original mix, less is better and that prep will last for months to come. By contrast, D1, which is not sold anymore, would only last a week, and you had to apply it generously. I know this because I spent significant time with each. If you use the oil correctly, they are all fast; but that is the trick - to use the oil correctly. Like SuperSlow said, you really do want to purchase oil from a vendor. That vendor will help you use the oil correctly. Jphn, in particular, has posted videos exactly how to use his oil, which should help...
