I searched in two different forums and couldn't find what i was looking for. I am currently using 87 octane but in the owners manual it says if i use over 91 or 93 you get better acceleration, so i was wondering how true this is and will i notice a difference if i switch to higher octane? Also is it worth it gas millage wise?

 

its like 2 dollars per ful tank.. just do it

 

u are just hurting your car, put some 93octane in it.

 

well actually, ive used 87 in my ss/sc 91 93 and 94 and didnt not notice anything, if i do highway during winter i always use 87, but tu run around i use 91-94 only.

 

its 2 DOLLARS just go for the good stuff

 

how much performance will i gain? noticable?

 

you wont **** up your car if the manual recomends it do it

 

h0l0caust you realize the ss/sc is supposed to run on 91 right? its not just reccomended like it is on the 2.4s. your just gonna ruin your car doing stuff like that

 

get 93. It's the only option.

 

i got a question, i run 91 octane. I can find any gas station around here that sells any more (i hate ca). i was in pep boys earlier and they sell octane boosters. is it even worth getting them?

 

91+ Ahhh

NO...

 

aha sucks i want to run 93 but only thing in cali is 91 except on military bases i can get 92 lol. but i dont know who makes the gas so i just stick with chevron 91

 

I can't believe someone would put 87 in their SS/SC.......

I cringe at the thought

 

ive definately noticed a big difference from 87 (when my dad puts gas in it) to 91.. the car responds quicker and since i have the airbox mod, it doesnt throw the cel.. on 87 it does

 

dont ask questions just put in 93
put yourself in your cars position, do you want steakums or a real philly cheese steak

 

its like putting regular gas in a mercedes. if your too cheap to put in the reccomended, why didnt you just buy an aveo or something lol

 

ahhhhhhhhhh use 93!!!

 

If you did put 87 octane, your ignition timing would retard to prevent knock but it will more than likely do it via knock retard.

Now, I highly doubt that you'd notice a difference if you're driving normal and light throttle. Higher throttle positions I'm sure your Knock Retard will be in full effect.

 

Actually... Steakums are pretty good...

 

There's a reason there are high and low octane maps. Unless these are modified 87 causes no detrimental effects to the engine. I've now been running 87 in the winters for the last 3 years and never a problem and I always go back to the stock timing maps for winter. This last winter I ran the stage 2 timing maps and observed no difference when logging knock. Keep in mind there is less power to be had though.

 

trust me 93

 

91+!!!!!!!
