Race gas pump vs concentrate.

All I can say to the crap I brought up is I listened to the difference on the headphones. But I am only using it as a extra barrier when at the track. On the street the car will run 94 all day. But you guys are right, if your trying to take 91 up to 100 and need 100 octane then I would not use it at all.
