Anyone know if 93 is available at the pumps around the LA area?

I'm having a "spirited discussion" with a colleague and for the life of me I cant remember what the typical octane list is. I was thinking it was 89, 91, 93 but he's pretty certain 93 isn't a standard for the area...

91 octane is what you will likely find in CA. Usually if you find anything higher than 91 at the pump it will be 100 unleaded.

Thats such a bummer.

What are the new 2015+ GT's tuned at from the factory? Every ad I've read says they are rated at 435hp *with 93 octane gas*

Same tuning, the computer will pull timing to account for the slight difference in octane. You won't notice it. Our 2015 GT made 390 RWHP on 91 octane pump gas on our stingy Mustang Dyno.
