For all the V6 owners buying a lower grade octane, you are not saving much!

Why not? Different ECU programming for two very different motors.

Alex, I will take Camaro Engines for 200.

This type of engine does not require a fuse pull to reset the ECU.

What is the LLT.

You are correct.

Sorry, but this does not make your car run better!

I appreciate all the input on this. I've got a 2011 LS. Everyone is jumping back and forth between the different models. I don't care about spending money for my car. I plan on my 18 month old driving this beauty. I'm not savvy enough....yet... to understand all these facts (see name). I'm going to run mid-grade just to be safe and remain neutral till I know what the hell I'm talking about.
In the meantime carry on, love the debates

Look guys, we have gone over this so many times its not funny. The V6 has a compession of about 11.3 to one, any other car would require High octane fuels to keep this engine running , but because this engine is direct injected it can fire the fuel mixture and timing at the perfect time. Ok with this said that means that as long as the engine does not detect a ping or knock it can advance the timing up to where it starts to knock. Ok now with the premium fuel what that translates to is more timing advance.
The ECU on the LLT does not have dual fuel maps like the SS. Doesn't need them, the're two different Beast.

The LLT engines where designed to run on 87 octane fuel and generate 312 HP at the flywheel. I have not said running 93 octane will make anymore power, nor have I said you will get better fuel millage. All I have said is that the LLT seems to be a happier Engine. I have run 93 Shell in mine and well My car feels better for it.

And running 93 octane will not void your warrenty.

Nicely said ^
Picked up car last week it's the LFX not the LLT but who cares! I need to fill up tomorrow. Bc it's still a V6 I didn't know if 93 octane was too much or overkill but after talking to my dealer and having her reassure me 93 could only help I made my decision. SHELL 93
The new shell station by me only has 87,89&93 octane.

I've always run premium fuel in mine. I definitely notice the difference in performance and gas mileage. Also, at least in our market, regular fuel has a 10% ethanol mix which reduces gas mileage while premium has no ethanol. As many have stated, as little as I drive the Camaro, it's worth the premium price.

Bingo!!!! Well put. The entire deal with the manufacturer reccomending 87 is the motor can run fine on it and 93 is NOT a requirement......that said, it sure CAN benefit from the higher octaine. And no, running 91 or 93 has NO effect over warranty no matter how it can be interpeted.

I hate everytime I see one of these threads. There are always the guys coming and spoutin off what they think they know and it usually goes like this:

"V6 was designed to run on 87 so why run anything higher....you are wasting your money...blah blabbity blah"

Nobody is saying running running premium automatically adds 50 horsepower. But it has been shown time and time again via dyno runs and on the road monitoring systems that the LLT engine can and will run slightly higher timing more consistently when running on premium fuels.

If you guys can't accept that for whatever reason, being it due to your hard-headedness, or the fact that your SS doesn't do it...sorry.

First off, let me say that I use Exxon gasoline. Having said that, I used their 89 octane from the first day. Over time I noticed a great amount of "soot" in the the tailpipe and on my garage floor (wasn't happy). Decided to switch to 87 octane to see if there was any difference. The results were: No difference in mileage, car runs the same, and 95% of the "soot" issue has disappeared (garage floor is clean)!

[Camaro731]

If I had a 1990 Honda accord I would be putting 87 in it, so why would i put it iny new 2012 V6? Bc it CAN be used in it... No only the best for me sorry and I'm not worried bout soot..soot?? C'mon man!

[JoshBobGuptaMarley]

If you like your car buy it the best gas...if it's a rental or your friends car well, buy the cheaper gas.

Soot? Really, you are worried about soot?

There is much misinformation in this thread. And very few facts.

Each individual engine is different. The chance of two V6 engines being the exact same as far as individual fuel octane requirements is remotely low.

If you feel like buying 87 and you're happy, then buy it. If you feel like 93, then buy it. The real performance difference is likely so minute it's not worth the electricity used to send a dissenting post to a forum (assuming you're using good quality gas to begin with). Just don't waste your money on race fuel on a stock engine though. If octane is too high, it'll be detrimental to your performance similar to as not having enough.
