yeah... civics don require high octaine....

Stock, yes 87 octane is fine.

lol i mean i dont know alottttt about cars... but let me ask yall this ... whats the pont of putting in HIGH GRADE once every like 7-8 fill ups ? .. i mean its like you eat mikkie deeze 5 days a week and then on sat and sunday u eat some veggies and rice cakes :shrugs: u think that means u will benifit from the 1 day of vegggeis.... prolly not

Shell 87

I don't touch Sunoco. I read a few threads on here about people having problems with Sunoco gas.

Anything thing but Esso.
Normally Sunoco.

I use nothing but 91 (I think?) Pioneer.

why do you guys waste money on gas with stock engines, with swaps its diff, I NEED, lets rephrase, NEED 91 for my car to run properly, but a stock civic does not lol

sunoco 87.. just the regular gas.. or petro sometimes.. because they are close to me.

I'll second that. My hatch was lucky to get 89 once in while.
My Lude needs 91+ (why an '89 needs high octanc eI don't know).

My next hatch will get 87 until things require premium

whoever has the cheap regular gas and happens to be on my way gets my money

people, higher number doesnt equal "better" gas, all it means is that is has additives that make it less prone to preignition... so unless you are running high compression, you are wasting your money

high octane fuel wont even burn completly and cleanly in an engine that is not designed for it as the conditions in the cylinder might not be optimum for its proper burning point.

ok here's some info for the newbs/douches

when you compress air it get's hotter
high compression motors compress the air more (obvious)
gasoline engines run a mix of air and FUEL
so you bring the air charge in and the pisotn is coming up compressing the air

the air is getting hotter and hotter and hotter as it compresses more and more then boom is pre ignites from the heat of the compressed air instead of the arch of the spark plug

high octane fuel is more "stable" and wont' ignite as "easy'" so it won't preignite etc from the compressing of the air in the cylinder that is why you run high octane fuel.

you want to run the lowest octane you can get away with basically

oh 94.... thats a rare find down here... we only get up to 92 here...

i use chevron or 76 regular 87 (aka george bush stolen gas)

Typically anywhere that has it cheap but I prefer petro cause I get the 0.02 cents off per litre making it even cheaper. Regular gas for my stocky motor.

Last time I check my stock SiR takes 91+

Usually PetroCanada for the points.

89 or 91 in my stock CX....why? Cause i drive like 7km's to work and when i am on the highway i find i get a touch better mileage. Im also getting a new cat and premium burn's the **** out of your cat. And now its a touch louder.:thumbup: I grab petro or sunoco.

i used to use sunoco 94 all the time for my b16. over time, it started to run like ****. i found out they add alcohol to increase the octane rating or something. i switched down to 91 like my manual recommends and i get much better performance surprisingly.

89 @ esso....

by the way, are esso points better or the petro points? my sister uses sunoccco cause she uses her CAA card...

Etenol (sp?) is added actually.

Ethanol.

I used to run 89 octane, dunno why really, must've been habit, my dad filled my car up with 87 runs fine, looks like I'll stick with that now and save my 5-7 cents per liter.

nothing but the best!!! SUNOCO 94!!! u have to baby ur car man!
