i used to use RP religiously in my honda... but that's only cause i get it for way cheap and we always had it on hand at the shop i used to work at. i was just that lazy about going to get regular oil...

and the best about Royal Purple... it tastes like grape!

Here's a breakdown video from June 2018...

Hahaha I was reading through the posts in here thinking the same thing. Nice to see someone else in here knows a thing about a dyno graph and how a engine makes power.
