I have a '97 camaro ss and have been using regualr gas since I bought it a few months ago. I noticed the other day that the manual and a sticker on the gas door calls for premium gasoline. I have not had any problems running regular gasoline and prefer not to switch to premium due to the higher price. What do the other ss owners use? Can using regualr cause any problems down the road?

Nope just make sure you change your fuel filter every so often and you should be fine. It's just a higher octane fuel...you wouldn't notice a big difference in using it unless your car was majorly modded.

I run premium too for my 94 Z.
With a 97 SS, you definately need to run premium, at least mid-grade. The higher octane gas is recommended because of the higher comp. ratio on the LT1 engine. If you use regular, there is a better chance of detonation and a better change of wearing something out quicker or breaking something quickly. You may not have problems now, but why wait till something breaks before you change?
If gas price patterns are anything like around here, premium is only .20 more than regular, so you are only paying $2 more per 10 gallons of gas. Small price to pay for a higher octane rating.

yea run atleast midgrade to reduce the risk of possible issues in the long run. cheap insurance if u ask me.

there was just a really big report done around here by some news places saying how most gases around here at the pumps werent even premium when you thought you were getting it, you dont always know what your getting out of the pump basicly is what im saying anyway

I thought that the LT1s were ok to run on regular, or at least if you wer'ent abusing the engine. :confused:

I'd run premium. It is calling for premium gas because that's what the cars computer is programed to run on. With a higher octane it can get more performance out of the car without having to worry about detonation.

With the reverse-flow cooling, GM decided to take advantage and up the comp. ratio on the LT1 to 10.5:1. Running regular gas is IMO a big risk just to save a couple bucks at the pump.

I run premium in my v6, but that's because I have the high and low octane tables tuned to completely optimize the higher octane, timing wise

The manual "recomends" premium but it also says you can run mid or 87 grades so I doubt you will hurt anything other than your performance or gas mileage

You can run any grade of fuel but if you run regular the PCM will retard the timing (low octane routine programmed into the PCM). As soon as any pinging is detected the PCM switches over to the low octane settings to prevent damage to the engine. It will recheck every so often while you are driving to see if it will ping with the "normal" timing tables in use and switch back to them if no further signs of detonation are detected.....one of the true benefits of OBD II.

Running 11:1 on 93+ ... However it's been down because I'm rewiring it and that just happened to be when the prices went really crazy so I guess I can't really complain.

Lmao... NAH... with all this fancy welding I'm learning I'm putting a trap door in the floor boards so I can do a Fred Flintstone for when the gas prices get outta whack again.

So, Earl will be losing some weight huh?

LMAO! I muddled my way through that one... It started off not too bad, then went to hell after the first line... lol.

Earl lose weight??? That's like physically impossible... kinda like alchemy, we keep trying, but it's never gonna happen. When we cut his diet back, my middle kid slips him food on the sly, and he further mitigates any decline in approved dietary allowance by supplementing what he receives from us and her by a trip to the trash can. (The fat bastard... gotta love him though.)

You know... I'd be less hard on him about his weight if he would just let me sit through The Long Riders ONE TIME without him flipping out at the TV.

The Long Riders... GREAT MOVIE - Western about Jesse James, etc

Earl don't like animals on TV, horses the least of which. Anytime a dog or horse or any other animal shows up on the screen he tries to attack it... jumps at TV snarls, flings spit all over the place. DRIVES ME NUTS. I've thrown remotes, kids toys, you name it, but nothing detracts him except food. And if I'm getting up because he's attacking the TV, he sure as shit is NOT getting food...

The crazy SOB actually has commercials memorized so whenever he hears the start of a commercial he knows has an animal on it he comes running from whereever he was to attack the TV. He could be all the way on the other side of the house, and within the first 3 or so seconds of the commercial he's jumping at the TV.

If he was human he'd probably have committed suicide because of the way I tease him about being fat. If he'd quit with the attacking of the TV, I probably wouldn't tease him so bad.
