Shell Gas and Your Z

Omikron

So, was chatting with the installer when I had my CBE installed a couple days ago. I guess there has been a couple 370Z in and out of there in the last few weeks. He was telling me that our Z are very particular about it's fuel. One of the guys that goes up there has noted that pretty much any 93 that he buys drops his power by 15-20 rwhp on the dyno... with the exception of Shell. They have proven it twice to my knowledge ex.; let the tank run practically empty, put racetrac or kroger in it, dynoed. Then let it run dry and put shell in it and there is a big difference.

Anyone confirm or deny this or is this just coincidence bs?
