Top Tier Gas makes a difference

Same problem here. The dealership filled it with 87 octane regular when I picked it up. Nothing worse than having an engine pinging while you're trying to break it in. As soon as it got down to a half tank, I filled it with premium and all is well. The manual says regular can be used in a pinch but I won't. As for top tier fuel, it just has more/better detergents and would be more of a long term benefit to keeping the valves, pistons, and injectors clean. Should not make any difference to power or running since stations buy fuel from pretty much the same refining stocks and just add there own special blend of detergents and put their label on it.

Well if you don't, your teeth will fall out. The engine won't fall out

It's the typical overreaction that occurs in innocuous threads like this. Some people have a tendency to think their way of doing things is often the only/best/right/etc way of doing them. There was no attempt to help the OP or anyone else.

So called top tier gas comes from the same refineries as the cheap stuff. Only difference is additives. You probably had low octane from the dealer. Just remember high octane doesn't make more power. The computer senses the higher octane fuel and advances the timing accordingly, that's where the more power comes from.

I hope this is not anther neverending thread argueing about octane and power and brand name quality. There are plenty of those here if you search.

I understand the fuel rating and the timing being adjusted to prevent pinging.I was just thinking that this has happened to others and did they also feel the difference.I worked in several dealerships as a tech(before I decided to climb poles and play with electricity)and have watched the tricks of some salesmen.

It just killing me, all the folks on this site that think GMs use of "recommended" means you can cut corners. And they repeat it like a broken record in ever gas thread they see.

Regardless if the computer can deal with it, it shouldn't have too.

The knock sensors should commit suicide from boredom.

Sorry for being harsh, I just feel bad for those engines.

Now you are just twisting the words around. The engine does it just fine and was designed to handle 87 octane. The point of pre-production models was to test this precisely and tweaks were made for it to work just fine. Several in the fleet saw 87 octane and only 87, they had no problems whatsoever, the performance was good and the exhaust note was also good.

If people don't want to spend the extra 15-20 cents per liter (or whatever the difference is in gallons) then they don't need to. Feel bad for those engines all you want, but they were designed to handle it, it simply performs better with higher octane, which may not even matter to many on this board.

That all sounds well and good but my car had excessive pinging under mild to medium engine load with 87 octane fuel that was put in by the dealer. This was on flat roads and cool temperatures. The knock sensors and ECM could not completely compensate for it. If you want to put low octane fuel in your new SS Camaro, be my guest. I however would strongly not recommend this practice to anyone else driving a V8 camaro except as a temporary situation until premium fuel can be found. Fuel variability, hot weather driving, carbon build up over time, and mountain pass driving would only make this worse. I consider any pinging to be potentially damaging let alone a performance killer.

Will somebody fix that
