Even though I wear a size 9 shoe, I notice that when I put on a size 13, I run much faster.
I've googled this to death and can't find 1 article to support using higher octane on a well maintained engine if all that's called for is 87 octane.
The cost savings over years (and gallons) of gas purchases would buy you a new engine if you stick to regular.
