Royal Purple in Lexus LX-470, Honda S-2000 & all 3) Honda 4S BF-225s...
Before I realized 1 of my Honda BF-225s was using oil, I let it get so low the engine kept shutting down due to low oil pressure. When I finally checked it the motor held 4 qts (8 qt capacity) of RP. I'm convinced using RP (vs. conventional oil) saved that engine from a catastrophic failure... & that was >300 hrs ago ;)

that's one problem with royal purple, my engine was consuming oil

I am not a mechanic but a mechanic told me it is so slick it blows/leaks through seals
I've heard that before... I also use it in my OB Lower Units & I think it helped my fuel burn...
