I've been a proponent of RP since the early 90s.
It's really good stuff and there are plenty of testimonials.
I just did an oil change on my big mower, switched to RP after 18+ years. 72" Bad Boy with a 27hp Kawasaki V-twin, water cooled.
After the oil change and mowing for a coupla hours, I idled back to the barn for a cool down.
RP had slicked up the motor such that the curb idle was up 500RPM.
Had to adjust it back down.
