OK Folks, for some of you that are really oil tech savy, can you provide some input on this extream pressure test below?

Not trying to start anything but came across this and was wondering what the bigger picture is.

Thanks

interesting. I'm sure there's more to it. I've been using royal purple in my mustang for awhile and was considering changing it up due to the expense. but after 100,000 miles and many nitrous assisted drag races it doesn't burn or leak a drop and after seeing this, guess I'll be sticking with the purple. Too bad they didn't test amsoil-that's what I use in my valk.

been posted before and responses including amsoil white paper test.  In SAE tests amsoil and mobil 1 comeout on top, RP does not do so well.
