It sounds like amsoil is a really good product to. I dont know which one to use and you both have great stories it is making it tough on me to decide which is better. I do know i see royal purple marketed a lot more on tv shows, websites, etc. as opposed to amsoil. In all honesty they are probably about the same. Does anyone else have an opinion on which is better or any stories. Also if you know of another brand or vote other and think it is a better product let us know.
