Yes. I used to be able to 94, but the one gas station doesn't have it anymore, so I'm running 93. I will run 92 if I have too.

Heck, all I can ever find is 91 octane for my Cayman. That is the normal "premium" here in Missouri. The car seems to run fine on it, although if I could find 93 or 94 octane, maybe it would run better yet. I do try to avoid the 91 octane that says it contains methanol, since the methanol would indeed reduce performance over a comparable "straight" 91 octane.

Octane Ratings
I write monthly technical articles for a few dozen PCA Regional Newsletters.
One in particular touches on this point.
Here's the complete article: http://www.pedrosgarage.com/Site_5/Octane_Ratings.html
Happy Boxstering,
Pedro

Your Porsche will actually run on Regular because of the Variable Timing. What you lose is performance and gas mileage.

Easy Flav, we are all friends here. No need for insults.
The fact is our cars are pretty smart and they will run on 87 octane, but they were designed to run 94 premium. Run 94 when you can. If you are stuck in commiefornia 91 is the best you can do, and 87 only if you have no other choice.

Oh, so in the unlikely event (but it could and does happen) a 986Forum member follows Jcb986's advice, and their engine goes BOOM, are all you naysayers going to chip-in and bail them out?

Thoughts about gas and engine oil elicit strong feelings in some folks.
That said, we need to lighten up.
The Owners manual provides advice on fuel requirements. That said, owners often ignore that advice.
To each his own.

Richard, if your going to delete and edit posts, I suggest you remove the irresponsible post that suggests using 87 is acceptable and safe.
FYI, your buddy MNBoxster, aka Jim, aka Andy, aka Lil Bastard, aka Red Line employee, continues to make friends on other Porsche web sites for enthusiasts, and has received bans there too. Just like you did (banned 'em).
We need to give Forum members better advice. You have this responsibility as an co-owner.

Does anybody know if it is possible to find higher octane than 91 in California at all? Preferably in the Bay Area - or is the 91-octane premium definition a state-wide thing?
Thanks,
Lars - just north of San Fran

I always use 94 or 91 if I can not find 94 but I never have, or will use 87.

You can get race gas, 100oct unleaded but it is about $8.50/gal. I ran a 100/91 blend for a while on track days but now just run 91 pump gas. In Calif we are "special" so we get "special" gas formulations in an attempt to improve emissions. Welcome to the Golden state.
