I wonder if RLV has anything to do with the actual refining of that oil? Maybe, perhaps, they have it canned by someone else in a can with their label on? Who knows what oil it is. Maybe they added some nondescript ingredient to make it their own? Not saying it's not good oil, just questioning its heritage.
I have personal experience with someone buying commercially available castor oil (it's all the same) printing a label, put it on a plastic bottle, and selling it as their own. Amazingly, there were people who swore by it! The person who did this has a stellar reputation in the karting industry. Karts, engines, pipes etc. etc.
