Hell you dont even have to turn to the manual for this question... Have you put gas in the car yet? There's a sticker inside the fuel door...

91 is sufficient. 91 is all the California ppl get anyways. Given the choice I woudl still get 93.

As regards to brand, this is something that I feel is important. Any brand named gasoline could be used. The key thing is those big named brands put in additional additives that clean your injectors, and your engine. So yes use them. BP, Shell, Chevron, Texaco to name a few all have those in their premium 91+ gas. You can identify them as they will brand them:

Shell: V-Power
BP: Invigorate
Chevron/Texaco:Techron

99.9% of people agree with this. Now what people don't agree on is which is better. I'm think theses top tier brands are all the same. What most ppl don't agree on, but what I do is consistently use the same brand gas for the life fo the car, for me 93 Shell V-Power. If I can't get it on my road trips, I'll get BP 93

I work at a gas station and by law gasoline is required to have these "additives" that will clean injectors, engine, etc... Yes, BP, Shell, Chevron, and Texaco may advertise that they have this or that which means that they probably added more of the additives that were already there. It's like this... everyone needs a certain daily dose of calcium but adding more calcium pills sometimes doesn't really do anything. We urinate most of the excess calcium from our body. So having these extra additives aren't really essential. It's all marketing. All I'm saying is that you can go to any gas station (branded or unbranded) and your engine and injectors and whatever will still be cleaned.

Just an FYI Arco fuel is BP...lot of people don't realize this. In Cali. all our fuel comes from the same refineries, its after the refinery do certain manafacturers put their own additive such as Chevon with its Techroline.

To the OP, the cars rating of 414hp is with 93 octane. You run less you will get less, I go as far as blending 4 gallons of VP Racing unleaded with every tank full and it gets me to 93.2octane.

This...I had a friend who worked for Chevon as well as Atlantic Richfield CO or ARCO who basically told me the same thing.

Especially here in Cali, where all the fuel comes from the same refineries.

You can blend in a few gallons of 100 racing unleaded to get you to 93. The car will run better. I see you are in the 310 area code. Several stations offer it. There is Pico and Barrington 76 station, as well as the 76 station in Brentwood on San Vincente and Bundy.

Not quite right. I worked for a gasoline wholesaler in Northern NJ. We'd buy generic blend gas from the refineries. Gasoline is a commodity that is refined all over the world. Delivered price determined where we bought it from. In many cases it came from Europe although not so much now - remember, price. Not much if any additives from the refineries - these are expensive. Each "name brand" would load up their tank truck and then pour in their own additives package. Some of the brand "X" trucks would put little or NO additives.

So...you are better off buying a top tier brand and 93 octane if you can get it.

But it is required by law to have an x amount of additives for the engines.

You may or may not be right, but I don't work at the wholesaler any more so I cannot ask the question. You're not thinking about ethanol and other environmental "friendly" additives are you? However, you may be sure that if it's true the refineries will only add the absolute minimum additives required by law.

I'd recommend Shell or Chevron 91...and since I'm in Cali, I use a bottle of Lucas octane booster every other fill up....

Amazon has a very good deal on Lucas octane booster if buy by the case, comes out to be about $6/bottle...vs. $9.99 at Pep Boys and Autozone..
