As to the recommended octane, if you really want to save the money and you always take it easy driving, you could use regular. But who buys a v8 camaro to baby it? I recommend premium, for an extra $5 a week to get the performance you paid for in the car seems worth it to me.

Ditto, I run Premium in my FJ, I log at least 600 miles a week in that thing and the difference in gas is what $7.50 a week...? worth it for sure! It's just a V6... a very good V6 but still if your getting a Camaro worth the extra cash in V8 or V6 form. Also if you buy your gas from a mom and pop store that buy their gas from some unknown suplier... you will most likely get dirty gas, I have owned 7 different vehicles in the last 10 years and have found that Chevron Premium actually works best for most of those vehicles, not that I am promoting CHevron, I'm just saying based on my observations I get the best performance from it.
Too studies have been done that have shown vehicles that start out running on say 87 octane and run it for a while adapt to it, then if you go and switch it up to 91 octane which may or may not be the recommended octane, it will actually run worse than what it would have had you started with that octane and vice versa... with the modern computers in the vehicles they adjust and learn based on your diving style and fuel etc... this drove me nuts with my 2003 GMC, the transmission was stated to "learn" my driving style, well problem with that is that my "style" changes on my mood and what I am listening to on the radio... so sometimes when I wanted to get on the throttle it would be confused thinking he is(me) putzing around town... other times Id start to take off from a light at a normal pace it would start out in a higher gear for a while then !*BAM*! it would decide to drop a gear or two and slam me head into the head rest while making a loud clank sound... anyway my point being, run the recommended and stick with it... you will get much better results it's like feeding a dog different dog food every time you go shopping for dog food, it leads to finicky eating... not good as most dog people know, same goes for your car, leads to finicky performance...
