87 on my 2010, i keep telling myself i am going to jump up to 93 for the summer but everytime i get to the gas station i dont really see the point. i cant imagine it would make that much of a difference in daily driving. if it does someone correct me.

If you're not "tuned" to a higher octane, don't worry about it. Run regular and you'll be fine.

The car will adjust ignition and retard the timing for higher octane levels.
I'll be running 93, I'm conditioned to it for running a turbo car for almost 3 years, so the price doesn't even phase me. $1.20 per fill up, not a huge deal. Costs me $60/year extra for fun, I won't complain.

Octane recommendations (Bullitt™* Mustang only)
Your vehicle will run normally on 87 octane regular fuel without
damaging the engine, but premium fuel with an octane rating of 91
(R+M)/2 or higher is recommended for best overall performance.
* ™ & Warner Bros. Entertainment Inc. (s07)damaging the engine, but premium fuel with an octane rating of 91
(R+M)/2 or higher is recommended for best overall performance.
Press Release: Engine performance is further enhanced through the use of an innovative adaptive spark ignition system, new for the 2008 Mustang Bullitt.
The system can sense, within a few seconds, what type of fuel is being injected into the motor and adjusts the spark to provide maximum torque at any given speed – and as much as 10 pounds-feet more between 1,000 and 4,000 rpm.
Bullitt can run on either premium or regular fuel. Ford recommends premium fuel for optimum performance, but the adaptive spark ignition will adjust the spark to burn regular fuel without damaging the engine.

In my 2010, every tank (minus when the dealer filled it up) has been on 93 octane. More efficient for the engine and as Charlie said, it adds to the mid-range torque. But now that I have some engine mods and a tune, I reap more of the benefits. 
There was a previous thread started about it a while back- See here: https://themustangsource.com/showthread.php?t=478748 for anyone seeking some more input.

Same here. Oregon has only had 91 until the past few years when 10% eth was mandated year round. Then it crept to 92. But I think that's because ethonal has a higher octane (though lower energy) content. So I think its still 91 octane dinosaur with 10% eth mixed in.
I don't know how or why some areas get 94??

Even if you dont run a custom tune, using premium fuel just makes your car run better. Btw, I recommend Shell V-Power. I was a Sunoco fan, but V-Power seems to burn better (???) .

Walt, would love a link to your SVO project. I had a bright red 86 in the past. I would love to find one, but only 9,844 (I think) made..... I did see one outside of Pittsburgh last Saturday night. Easily the best looking Fox Mustang.

Some of you have 87 and 93 available in the same town? I've always lived in places where the lowest and highest available were separated by 4 points...so 87-91, or 89-93, but never 87-93.
