The extra octane can make a difference under certain driving conditions, in any engine. Last time I took a road trip to Canada, I was running 94 octane up there (which you can't even get on this side of the border) The difference on the highway, especially on the mountain passes, was remarkable.
I would never waste it on regular city driving though, even if I could get it here.
