Here are my questions regarding if this is a controlled test or not:

-how fair is it to compare high weights against lower weight oil

-how does royal purple come out on top when RP goes through more poor rated creation process.

 

Also surprised that RP did that well, especially considering some of the negative stuff I've read on the boards, e.g.: http://forums.corvetteforum.com/show....php?t=1855307
