All that high dollar oil is a joke and does not protect anything any better . They do however make power on dynos etc cause when its new “very few heat cycles” the oil is so slick it shows on the Dyno ,but aftera few heat cycles it breaks down FASTER than a cheap ass Dyno oil …yes I saw it and tested it with my own eyes and hands with proper testing equipment.

MOA ftw. Whats your cost on it? I dont get much of a break at the stealership

i’ve tried both amsoil and royal purple in my 954rr and amsoil seems to last and not break down as fast in my opinion.

Is that a visual or did you have a anaylsis done on them.

I put in royal purple and started burning out farther in third.
