Guest Potent68 Posted June 20, 2003 Share Posted June 20, 2003 Am I wasting my money buying the 93 octane stuff? Basically' date=' Yes.. Octane does not give you more power. I dont know how many times I have heard ppl putting higher octane gas in their car like it is supposed to make it more powerful. Not to mention the countless times I have heard of newer cars failing smog when they use "premium gas" and end up with all kinds of deposits and crap from incomplete burn. Octane is for a resistance to burning. You want to use the lowest octane possible in your engine. Higher octane is for engines that need it because they will ping (pre-detinate) because the compression is too high (whether it is a hi-comp engine, turbo'd, blown, or supercharged).[/quote'] I do not know you, nor do I know how much knowledge you may or may not have, but unless you know of any of the character traits of an LS1, you really should avoid giving advice pertaining to them. The LS1 can be a very picky motor. Many, many people have to fight pinging. Do you really believe that GM was supporting Chevron when the recommended that people use premium in their vehicles? Please do not think this is an attempt to flame, I'm just trying to clarify on a few things. You are correct when you say that higher octane is needed when running higher compression, turbo's, and s/c's. And there is also a reason that you don't run premium in a Honda Accord. Why? Because they are not designed to run on it. Countless times working for the dealer we'd have people come in with their Trans Am's and Formula's not running right. Diagnosis? They were running 87 octane. They ran it to almost empty, then refilled on premium, and reported back to us their car had all sorts of new power, and was running great. Okay, I'm done.

Guest Nic-Rebel450CA Posted June 21, 2003 Share Posted June 21, 2003 I do understand that you dont know me so you may not have confidence in my responses so by no means do I take it as a flame. But the truth is that internal combustion engines all operate under the same principles. Octane works the same way in all engines, and fuel burns the same way. An LS1 is still an internal combustion engine. In any internal combustion engine you want the fuel to burn as easily and efficiently as possible. Octane prevents burning to enable high-comp to fully compress the charge before spark causes detonation. If a car seems to be more "powerful" after switching to higher octane it would ONLY be because the charge was combusting before the spark (essentially like having the distributor turned to fire a couple degrees or more early.) Hope that clarifies it for those of you who needed more info. Quote Link to comment Share on other sites More sharing options...
