Found this on internet. Never purchased any since never found a place advertising R99 fuel.
"R99 stands for 99% renewable diesel and 1% petroleum diesel. Federal rules over alternative diesel fuels made fuels requires that manufacturers of non-petroleum derived diesel fuels must blend a minimum 1% petroleum with the fuel to generate a Renewable Industry Number or “RIN” under the US Federal Renewable Fuel Standard."
