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

 

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

 

E85 = best power





















































jk dont blow your **** 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
