93, yesterday spent 39.75 to fill up . Unf*cking believeable. Maybe its time to nuke their *** and steal their gas! Only kidding.

94 octane tune. I paid $1.22 CDN a liter the other day (Toronto, Canada). About 4 liters to the Gallon make it $4.88 CDN a gallon ($4.29 US). I wish I was paying your prices.

93 with my Roushcharger. Don't bother putting in anything other than 87 unless your tune calls for it. You'll just be wasting money.

My GT runs on love.

Here in Sweden our Regular is 95 Octane, but I'll propably be running it on 98 Octane. (Havn't got the Stang yet, just a Couple of more weeks!!)

We also have "Shell V-Power" wich is 99 Octane, and also optimised in other ways for cars with Muscle Engines!
I'll see if I'll try that in the Stang aswell

I run 87 octane. I have no other mods presently other than a Borla cat-back. On 87 octane I get no pinging whatsoever. In fox body mustangs I have owned, they would always ping on 87 octane, so I would buy 91-93 octane. Unless you have a custom tune or are getting pre detonation on acceleration, save your money and buy 87 octane.

Only the best for my baby, 93.

Have never put anything in it other than 93 when around home, or whatever is the highest I can find when on road trips. Lowest that has been in it was 91, but topped that off with a little Torco to make up for it.

93 octane here. Its my daily driver and 93 octane costs about 2.99 right now. Its just an extra $2.40 to go with 93 over 87 (plus I have to for my tune.
