not calling you guys stupid, just saying you'll find whatever you want to find with oils. What works for your app based on what you see as results is not externally valid, i see way too many blanket recommendations based on little more than a hunch. And my guess is RP gets 80% of its business from this, cuz its certainly not from analytical data tests
I worked for Royal Petroleum for 3 years and many of the owners and bosses worked with or around John Williams during his hay-day, master of marketing and proprietary "secrets" yes, but what's produced today they wouldn't want to be compared in USE tests against most any major manufacturer on the market.
