All in all u can run whatever u want but as the manual states for best results premium is the best choice.
and i only tear into people if they deserve it.

If you had a clue you'd know that it will only pull timing if it detects knock, which you won't get if you drive it as a commuter, which is how I drive the T/A. If I want to play I'll take the Hawk out. Sure, if you drive the car hard than put premium in it. If you don't have a need to prove your manhood on the street at every opportunity, 87 works just fine. Around here there is a 35 to 40 cent a gallon difference in price. I'd like to meet you in person sometime to see if its just the computer in front of you that makes you feel like God of the LS1's.
if you're going to bitch over the price of premium, sell your ******* car. it was DESIGNED to run on premium. the only reason why GM put the timing retard feature into the car is because they knew tightwads were going to bitch over the price of gas and use the improper fuel, costing them a lot in warranty repairs from damaged engines.
why would you buy a V8 performance car, then bitch about the cost of fuel and use the improper, performance and efficiency-robbing octane? i suggest you invest in a honda civic. you'd be better suited driving one if it's all you can afford.
no one should have to explain the benefits for running premium V. mid grade....
if you dont understand the basic concept you honestly shouldnt be driving a car with a v8 in it......this goes for anyone

maybe my car a fluke. i messed up one time a put mid grade in my car. Shooot it sounded like some one threw a bunch of bolts down inside the damn thing. Thank goodness it was only 6 bucks worth. I fixed that real quick.

it's good you found this out. you could have been putting midgrade or less in your car, having less ping and not being able to hear it so you assume it's fine and run it for the longterm, then learn the hard way when your motor gets damaged. people put WAY TOO MUCH FAITH into the computer pulling timing. they think that because the computer pulls timing, the car is safe. it's just a precaution. it's not a fix that makes it as good for your car as premium. i'm glad you chimed in here.
Just a thought here...obviously there will be a loss of power with lower octane, but would it necessarily lose mpg too? Theoretically the PCM should prevent more fuel than can be burned effeciently being injected, so if it can't make maximum power becuase of timing retard, wouldn't it inject less fuel at WOT? Am I making any sense here? If not maybe I can at least get the thread back on topic.

that's exactly what it is. if you have access to premium, you should use premium. the car was made to run on premium. GM only says it's not necessary in order to increase sales as some people will just plain not buy premium. it makes no sense to buy a car designed to run on premium, then not put it in. you want to drive a camaro/firebird on reg/mid-grade, there's a V6 model. you want a V8? buy a mustang, they take regular.

Its true around here the gas has gone down hill pretty bad. Shell is still doing it for me. I am not sure how i feel about this V power cleaning crap.
