Someone will correct me if I'm wrong, but I'm pretty sure you're not supposed to put anything other than regular in the V6s.
I just got my V6 premium 202A, and I didn't see anything in the owner's guide about putting in higher octane gas. But then again I wasn't really looking for it.
The V6 benefits as much with 91 over 87 as the V8 does. Ford don't mention it for two marketing reasons:The manual doesn't specify what Premium gas will do for a V6 (p.289-290):
None. The engine is designed to use 87 octane, and there is no benefit for the additional octane and the cost associated with it.I have a 2012 Mustang v6 Premium 201A and was wondering if there really is any benefit to using 91/93 Octain...any comments are helpful.
Bravo, nice way to make the new guy feel welcome!Man - I've only seen this topic 100 times. Do a minimal amount of research before rehashing posts please. This has all be discussed before.
Life is not fair....in canada, 91 gas from shell is ethanol free ...
You won't find split ratings for the 6.2L V8 used in the Super Duty pickups either, but Mike Harrison, the chief engineer for that engine, said on another forum that you would see more power with premium fuel.jimmbbo said:None. The engine is designed to use 87 octane, and there is no benefit for the additional octane and the cost associated with it.
Never would I believe that we'd have an easier time finding real gas in our country than you guys. I'll just leave it at that.Life is not fair.
You did give me an idea though, I just checked to see if any US Shell was ethanol free and stumbled into this. Anyone ever see this before? Doesn't do many any good, no stations near me, but it might help some of you guys. Sure would be great for those of us with vintage iron too.

New or not - do your research. I put in a few months with no threads to get a feel for what's out there and what's not. Just because someone's new doesn't mean that we should oblige repeat posts. We're not 6 years old and don't need to be babied. Don't get me wrong, I love to help, but not when you can Google "v6 octane site:allfordmustangs.com" and find what you're looking for...Bravo, nice way to make the new guy feel welcome!
Why don't you be helpful and post a few links to some of those threads from here on the site on octane for 2011 and + V6s, we'd all like to read up on the topic. Since it's been posted hundreds of times that should be real easy.
The manual doesn't specify what Premium gas will do for a V6 (p.289-290):
Your vehicle is designed to use “Regular” unleaded gasoline with a pump (R+M)/2 octane rating of 87.
Octane recommendations (5.0L V8 engine)
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.
The website does specify that Premium will allow the V8 to perform at its optimum level:

Figured I'd further my point:
