hey guys. i had a quick question bout the 2.4 SS. wut gas does it take. im seein regular unleaded or premium....wut can it take or be better for performance of the engine....ill be gettin my car soon...cant wait.

 

91 or better

 

91 or better is recommended and it is all I use. it will give you better performance. 87 octane can be used though.

 

ok that wut ill be using....wut the power loss of usin unleaded

 

i have been useing 93 ever sence i bought it

 

yup 93 since day one. I even went to the gas station with the sales man when I first got her and filled it up with 93...

 

looks unanimous to me!

 

i don't know how many times i have to tell people this. dont be a cheap ass. use 93 octane.

 

It runs alot better on 93. I used 87 once and the difference was noticeable.

 

I never run anything less then premium ragardless.... stay with the good stuff... especiallyy once we start tuning the bastard..,.

 

we put 87 in the first tank,(didnt know) then went to 93, got 3 more MPG's and alot more power

 

Sunoco 94 since day one.

 

QFT!

I think the dealer gave me Regular, I did midgrade for 3 tanks, and was getting ~18MPG

Switched to 93 last night and I'm getting ~22MPG city. I think it's premium only for now on.

 

yes this is true. i think i should have my car sooner than aspected.....that should be fun for us, paul. but u know i have to drive it a good amount for moddin the hell out of it. ok thanks guys so 93 it is.

 

I've used nothing but Sunoco 94 in mine since day one!

 

i use 91 every fill, every now n then when i feel like it i put in 94 and it loves it

 

the 2.4 love octane, i wonder what 100 octane is like, because it the only fuel you can buy in china

 

i heard 106 is what u get in japan

 

106 it would purr

 

^^thats what im sayin, id luv to get my hands on some a dat

 

Nvm not here

 

octane is over-rated. its just "coverup" for the real issues with your car.
you raise octane as a last resort... not the other way around.

 

?what are you trying to say? Some car require higher octane, and how would it cover up the issues? Are you saying running 86 in my GTO would uncover the real issues or make real issues? If a car is tuned for a certain octane thats what you use, that or higher.

 

How do you like the GTO....I'm lookin at those more and more seriously.

 

A car can be tuned for a higher octane fuel. Decking the block, super/turbo charging for example. This in theory raises compression ratio which can cause detonation or spark knock. So we up the octane of the fuel which makes it harder for the gas to ignite deturing knock.

But people with older vehicles who have car troubles seem to think that a higher octane will solve problems.

Oil consumption and knicks on the CC of the head can cause knock, which are from problems in the motor. So people dump high test to help remedy the problem.

Another thing is the N2O, people think that it is a highly flammable gas but it isnt. it cools the air charge into the CC condensing it which in turn forces more air and fuel into the fire. It also separates and the oxygen becomes highly flammable. Which is why you need a timing retarder for the N2O. To much can destroy the motor.

Water injection is also the same design. Believe it or not windshield washer fluid injected as a fine mist can raise the octane per say. it cools the air allowing for more air and fuel creating more power slightly. but the real benefit is to be able to turn the timing up and the boost up for more power.

I run 87 in my SS. Its what the dealer put in it with me and thats what I will continue to put in it. I get 25 mpg around town and 35 on steady highway. My turbo coupe gets high test and so does my mustang Im for sure not putting it into the SS.
