hi, im very close to buying a ss/sc cobalt, but was wondering what octane is safe or recommended for this car? sorry if this is in the wrong section

If you dont run the engine hard you can use 87 even though its not recommended.. The minimum recommended in the manual is 91 or better..

I put 91, as recommended.

use 93 its $2 more a fill up not a big deal

most gas stations by me have 91 as the highest

91 or higher. I recommend 93 if you can find it. If not, use 91 and then get meth injection to make up for the rest and gain you some power and cooling.

Premium ONLY!

i use 110..its 1.75 more compared to 93

lol

93 here, if I could get away w/ 87 w/o detonation or de-tuning I would

Where in Jersey do you live?

All the stations by me have 93. Some even have pump gas.

If you have the SS/SC or TC just put premium. The savings with using lower octane fuels will be minimum. If you're considering it, why did you buy a FI car in the 1st place?

if you are really tight on money you can get away with 89 but 91 or better is the way to go.



Boost=premium

110 Octane smells the best.

Sunoco 93, and Sunoco 260GT on the weekends.

Use premium, nothing else. Sure you might be able to get away with using 87, but it's not worth your engine getting messed up for saving $2.00 when you fill up.

I only use Shell V-Power (93).

haha no cares:twothumbs

hi, 93 octane is better or you can use 91 octane + "octane booster" as alternative.

E85 = best power





















































jk dont blow your shit up please

octane booster is overpriced and pretty much worthless.

93, 105 at the track

i agreed for the longest time, and for some damn reason it works in my dads TBSS. i dont get it, only car ive ever actually seen gains in

Sunoco 94 :)

CH3NO2

...or CH3OH, but either way, you'd better get a different fuel pump and injectors...LOL!

GM only reccomends Prem. if ya go Stge 2. A stock SS/SC runs fine on reg. Fuel economy doesn't change from reg. or mid-grade. I get 36 highway with either. So for daily driving, save your dimes for more important stuff. MODS, then ya can start buying prem. gas.

what do you save each time at the pump, $2.00?

Theres no 93 stations within minimum of an hour drive away so I have no choice but to run 91...

why do people make a small thread into a 2 page thread when one answer is needed...geeezz

danm whoresssss

93 all the way:cssNET:

Exactly.....No one ever does the math, they just assume that it's way more. Those are the same people that will sit in their car idling for 15 minutes waiting for the gas that's 5 cents cheaper than across the street.

if you are really tight on money you can get away with 89 but 91 or better is the way to go.



Boost=premium

For the love of Christ... if anyone is that tight on money that the difference between regular and premium busts their bank, why buy an SS/SC? :lol:

ive used 87 for a year now, and nothing has gone wrong =/


soon to go to 91 just because every says dont use 87, but like i said ive had no problems.

People don't say it because they feel like saying it, they say it because the damn people that built the car said put premium gas in it. They would know. You have had "problems", they just haven't been evident to you; the effects of running 87 in the LSJ have been made clear and are all over the site.

So, is it the same with the LT, or is it just the SS engine that needs 91 or better?

put in regular 87 for your lt.

I only use premium in my 2.2. I get 5mpg better on the highway.

octane booster is overpriced and pretty much worthless.

not when it says "n2o under pressure" on the bottle...



















wait.....






















that can't be right....

use 91 or better, forced induction=premium, there are some people that will tell you you don't have to, ignore them.

Lots of threads that talk about similar topic. Use the search buttom its ur friend. And if you can afford premium dont buy the car. Premium FTW. 93 octane only.

theres only 2 places around where i live that has 92

so if you have a 2.2 balt lt you should just use 87???? From what i was told if you gradually upgrade from 87 up, your gas milage will increase. But then again i could be getting false information.

your gas mileage won't increase. if it does, it's in your head. keep to 87 and you'll be fine.

Bp 93

Clif notes
If you car recommends 87 use 87
If you car recomends or required premium use premium your get better performance and milage.
Yes the SC and TC will run on 87 but you will likely loose mpgs and performance.

93.....
