It's def. a 'results may vary' situation, and even the diff. between your local fuel at 91 vs. somewhere else at 93 can make a difference.
Heck, in some localities 93 is 100% gasoline with 87 being 90% (E10) so that can affect it as well - not just octane.
I mentioned the number of tanks for general reference since most have a LOT left in their tank when the light comes on. Mine comes on at about 9 gal. used, at least intermittently, out of 13 capacity and a max of 12 used for the LOWEST I ever took it.
9- 10 fresh with 4-3 remaining is a noticeable dilution.
For your use, in your region, it doesn't make sense to pay the extra.

|Blackfocus86||Yea. I run my tanks down till the gas light comes on lol. I ran about 15 tanks of 91 and 15 or so 87 all calculated. Big difference also driving south to work and doing little trips up north. Going down to Newport Beach and back to la about 36mpg. Going up north to the valley then coming back to La about 41mpg. Amazing stuff huh lol. But definitely no difference in mpg. Waste of money. As far as far running better on 91 from the pants on the seat felt the same to me. Then again I don't go racing or driving quick|

It's not easy to get a good comparison, have to change over and run something different for a number of tanks before getting any decent comparison.
Initially it's just a partial one, since the fuel is mixing with what was already in use.
Often a fair variation without a change as well, just due to different driving done on each tank full.

|Blackfocus86||I've ran 87 and 91 from 76 here in Cali Los Angeles. Same gas station same commute to work. Tried 91 cause I read someone here got a 4mpg increase. What a bunch of bull my mpg was the same with both gas lol. I manually calculated my mpg with 95percent highway at just over 70mph 36mpg with both gas. Will also add how inaccurate the mpg calculator the car has is. Been off anywhere from half a mile to 11 miles off lol.|

I ran 87 when I was strapped for cash, the reason I bought the focus, but now I paid the car off. The car ran just, well...okay. I never thought I would be running 93 in this car but after I got a few mods and a tune I had to try it. Premium will cost me an extra $250 a year and it is worth it for me.
If you plan to keep the car for awhile, which I do, I would get a 93 tune. Car runs spectacular!

I was using 87 but was getting a slight staggered pinging noise when I opened the car up. Switched to 93 and the sound has went away. Currently intake, headers, Tom's tune and exhaust.
