Why do people stress about premium!!!

In a really oddball related story...most of my friends have Stangs...they recommend low octane. After discussing how my Z runs better on high, 2 of them tried and said the cars felt sluggish compared to the lower octane rated fuel. Maybe they are crazy...I guess im trying to say if your car recommends one thing...its probably for a good reason. Don't go trying another thing, it might be more hassle than its worth.

No the point of the thread is for you americans to use my uncle Muhammads gas. HAHAHAHAH. Just kidding but the point of the thread is not to make fun but to see what drives people to risk a GREAT motor for 3-5 dollars???? Boggles my mind.

Alright this is the last time I'm posting in here I have better things to do. These motors do not all need 93 octane gas or even 91 octane gas. In the manual gm "recomends 91 octane" but it also states you may run regular gas in the engine but may not see "optimum" performance. The "optimum" peformance loss will only be on motors that are not in good tune or are ran in very dry and hot enviroments such as some of the states down south. For every 10 degree drop in air intake temperature you can drop the octane requirement of an engine by 1 point. Also for every so many % increase in humidy you can also drop the octane requirement. GM put 91 octane in there so that people that live in those very dry hot enviroments can't cry when there engine acts up. GMs sales cover a wide variety of climates so they put that in to cover there asses in case somebody that lives in the desert likes to fill up with regular. Hell even a cavalier will require more octane gas in those types of inviroments. So would some lawn tractors it doesn't mean that everybody has to use the high octane crap. I don't think I'll ever have to worry about putting premium gas in my car up here in Wisconsin we very rarely have hot dry days they are always very humid. You guys may not think 5 dollars is much but lets say you drive the amount I do I fill up 3 times a week so that's 15 dollars a week now multiply that by 52 weeks in a year and that comes out to 780 dollars. Hell a couple of years driving on regular and you could save up enough to build a nice strocker motor with higher compression that actually will need the high octane gas. Now you can either listen to my opinion a Engineer that makes a living designing Internal Combustion Engines or some guy that heard something from some other guy. Whatever you guys want to put in your engines that's fine with me it's your money and your car. So I expect the same attitude from you also. Oh and for somebodys comment that said if you put 87 octane in you car will drive like a v6 my car sure as hell doesn't drive like a v6 car. And that's about the stupidest comment I've ever heard.

PING means your pistons is rattling in the bore from being over stressed, I only run 94 octane, we have tons of gas stations around here, 3 to be exact that offer 94 Octane, Chevron being one of them. I only settle for that & when I was stock I ran 91 atleast. I didn't want to risk having the engine overheat & I would get on the gas for that brief moment causing some serious damage. Right now I wish there was 100 octane at the pumps, I'd pay an extra 10 bucks for fill up I don't care, aslong as I can go nuts on my timing its worth it.

what does the "ping" do to your motor? does just running lower octain cause a "ping" thanks for the info!

I've mainly only put 87 in for 10 years now with no problems. I tried 93 for a while (months) since everyone is saying it is better. I saw no difference in perf or mileage. I am back to 87. BTW, the difference here between 87 and 93 is like $0.50. That is $7 a fill up difference.
