I have a fully stock 06 SS/SC, what gas should I put in it? The reason I ask is because I looked at the dyno sheet from the article just posted on the main page and it seems to have lost power going from 91-94 octane? Ive been putting nothing but 93 in it... is that wrong?

 

no, keep it up the good work

 

if you want detonation use 87 ...stick to 93 regaurdless of what anyone says....your boosted better safe then sorry....especially when you start modding

 

GM reccomends 91+, so youre doing good with 93.

 

Does anyone have a station in their area that has 91 octane? There is only 87 89 93 available here.

 

^ same options here in south texas.

 

Should be have an octane rating of at least 91. It is safe to run an octane of 87, though there will be a noticeable power loss.

 

BC has 87, 89, 91, 92, 94. I use 91 as the manual states.

 

I only have 91 where I live
I went to a friends house out of state where they had 92 and wow what a differance the car felt like it had 871 blower on it (exagerating) but it felt better ran smother.

 

i use 94

 

Unfortunatley only have opportunity to run 91 so far. Nothing less though!

 

Yeah 92 sucks. I am going to miss 94 octane so much when I move to Kansas. Keep using 93.

 

Running 94 here.. have been since my first tank. Man it go's fast... perhaps that is due to my led foot and a new car.

 

the highest octane unleaded you can find/afford.

Doc

 

haha thats so many different nozzles to choose from! jeez, the pump must be as long as your car...exaggeratingly speaking.

I run 93 usually but sometimes 89....89 is fine considering I raced an r32 on it and still won...can't be too much of a power loss.

 

edit: you know what.. im not intoxicated at all and im also not completely sure if what i just said was accurate. so nvm this post

 

LMAO!!! An 871 blower would stick like 2 feet out of the hood! Not to mention it would surge like a ****, 500 to 1000 and back to 500 all day long!

 

Yea, so speakin of 91 octane gas (which is what i run), it costs 3.26 here

 

3.21 here. Steamboat, CO

that is the highest octane i can get also :-\

 

94 here

 

The Sunoco used to have 87,89,93 and 94. But now the have 87,89,91 and Ultra 93. What happened to the 94?

 

Is it possible that I get MORE miliage with Octane 89 than 91?? Maybe I'll try 94 next week, but I find ever since i started putting 91, it drains much quicker than 89. About the power issue, I just notice I hear the "whine" of my sc a lot more.... AND I LIKE IT lol... but seriously, I find miliage is better with Petro-Canada 89 than 91... bope, maybe just me... i dunno, let me stop rambling now lol...

EDIT: Forgot to mention that the power is the same, i find... Not a big gain... Something I'm doing wrong? LOL Maybe I should pump gas with my other hand

 

What about for the SS 2.4L?

I have just been putting in regular. (Gas Prices Suck!)

 

Read you owners manual, that should have the recomended octane ratings in it for your vehical. I'm running 87 in mine but thats cause I've got a dead stock LS. Failing that I'd run nothing less than 89 in an SS, and always the highest grade in the SS/SC that you can find.

 

91+ is also recommended for the 2.4 as per GMs website.
