I don't think you'll damage the engine, but you might blacken the plugs, while spending more than you should.

I think the manual says something like 87 or higher. I have been putting 92/93 in since I got it and have not had a problem.
Go to this thread...Read post number 4...Should just about sum it up for you. http://www.camaro5.com/forums/showth...t=v6+octane%27

You can always go higher, but should never go lower.
Lower octane in cars not designed for it will cause engine knock due to fuel ignition outside of the combustion cycle. You wouldn't think so, but lower octane fuel will ignite more easily, which is why it's not used in high compression engines. |

My HHR SS requires (in the owners manual) 91 or higher octane. Now that's just a little 2.0L ecotec that's turbo charged.
If I had a 312hp V6 Camaro, I'd put 91 or higher in it. That's just my two cents. What are you saving by going with lower gas. $2.70 a fill up?

If the ECM is set to maximize at 87 octane then you will actually loose power using a higher octane. Lower octane gasoline contains more BTU's of energy then higher octane.

Thats my thinking. At most 93 is 30 cents more than reg unleaded. So... 4-5 bucks mor eon a fillup max. If I can find 91, I use that, around here, with good gas stations, its 89 or 93...
I dont think it hurts the V6, would it affect gas mileage? Hell I dont know, the closest I am to a mechanic is when I am handing one money.

lol. If you drive a V6 just fill with 87. No need to spend the extra money. Higher doesn't benefit you at all. Doesn't increase MPG, doesn't make it more powerful... I thought I should have used Premium on my V6 as well. But if the Manual says 87... just do as it says. =D

As others have said, it's a waste of money to put higher octane fuel in the V6. It is designed to run on regular. You are throwing away money as you won't get any gains from higher octane fuel.

Gasoline Factors That Matter
The quality of gasoline and the additive package usually affect the rate of engine wear more than the octane rating. Basically what this means is that it matters more where you buy your gas than which grade you purchase. Regular Unleaded Gasoline The recommended gasoline for most cars is regular 87 octane. One common misconception is that higher octane gasoline contains more cleaning additives than lower octane gas. All octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against engine deposit build-up. In fact, using a gasoline with too high of an octane rating may cause damage to the emissions system. Mid-Grade Gasoline The octane ratings 'regular', 'mid-grade', and 'premium' are not consistent. In the United States, for example, one state may require a minimum octane rating of 92 for premium gasoline, while another may allow an octane rating of 90 to be premium. Check the octane rating on the yellow sticker on the gas pump rather than relying on descriptive labels. Premium Gasoline Certain high performance engines benefit from use of high octane fuel. For other engines, using a fuel with a higher octane rating than the vehicle requires sends unburned fuel into the emissions system and catalytic converter. This puts unecessary stress on the emissions system. For some vehicles, a rotten egg smell coming from the tailpipe signals use of too-high octane gas.
