If you didnt know you filled up with premium fuel, would you have noticed the difference?

When my brother drives my car, he doesn't notice any difference no matter what brand or octane I use. I'm pretty sure that in a blind test, people won't notice the difference of regular fuel and premium fuel.

Heck, sometimes we sell 95 as 91 whenever we're out of 91. Noone notices.
