I've read all over the internet, including their own website and it seems like it's a great oil, lots of people support it, and lots of people even go so far as to say it blows the other oils out of the water...
But if it's supposedly one of the best on the market, why does it lack the API starburst symbol?
It has the API Licensed "donut" symbol, but not the star burst symbol? Does that carry any significant meaning? I know a lot of people use RP long-term with no problems, so what's the deal? Why isnt RP approved with that starburst symbol?
