any one know the best octane for our cars so that they will perform at their best?

clstyle

89 octane

alot of people talk about
if you go any higher it wont do anything
it would actually sacrifice performance

and if u go lower it
would damage your engine

clracer97

why wouldnt 93 be better ?

r3mix3r

umm actually ur suppose to run 87 octane...

clracer97

ok who am i supposed to believe? could someone help me who knows what to use with a good reason why i should use it?

Bluesman

Don't wast your money on high octain gas. It is for high compresion engines. Ours is not. 2.2 or 3.0. High octain gas requires more pressure be fore it will ignite (burn). If you do not have enough compression all the fuel will not be burned and therefore you will have more deposites in your engine. Carbon on the plugs and valves. Not good.

Low octain in a high compresion engine can cause pre- ignition.
This can result in detonation and will cause diseling ( the engine continues runing after you turn off the ignition).

SickAcura

your suppost to use 87 octane thats what i have been using ever since ive had my car and it runs the smoothest on 87 octane trust a brotha

clracer97

so you guys would reccomend 89 for our cars?

Minch00

No, we would recommend 87! No reason to pay the extra 10 cents a gallon....the car was designed to run on 87. Anything higher could run the risk of messing something up.

matteichenfels

87

truraysa

I say 87, i tried running 100 octane and my car felt super slow and had weird smell. same result with 92 octane running 87 ever since. i think car and drive did a article on it but it was a accord v6 (same engine as 3.0cl's) and 87 produced more power and better milage. you can always will your tank with 92 and find out for your self

Bluesman

Are you actually reading the answers to your question? :wackit:

clstyle

so its


EIGHTY SEVEN!
in othere words

87 octane

infamouz trunkz

i dunno cuz i hav the 97 2.2 wit 90k n when i run wit 87 its kind of weak..but wit the supreme it runs better n smoother...

CLpower

87 on a 3.0, anything else you'll lose power

97Acura3.0CL

i run 92 octane at chevron, i use 92 for my vafc and adjusting the fuel. i know but i think my car runs a little better on 92

also has anyone tried that new fuel injector cleaner for the car, i just did it the take before last and my car has been feeling more pulling and faster and smoother. i recommend this to anyone its like 5something at kregans

anyone else run at 92 octane?

d5c5b

i notice tranny shifted better when i first started using 92 on my 2.2....so now i just keep using 92, maybe next time i get gas ill go back to the lower grade and see how it works... also, why would my tranny shift smoother on higher octane gas? i dont understand that?!...but it does!

CLpower

it's been dyno proven you lose power on anything else then 87. It is a complete waste of money and you are just clogging up your injectors because the car can't burn that octane well enough. I think it was Car and driver that did the test on the v6 accord. They lost about 14 HP running 92 compared to 87.

CLpower

that makes absolutely no sense

clracer97

i dont know if this is true but i heard somewhere that using low octane gasoline damages your engine. is this true?

CLpower

no, if you have a motor w/ high compression that really needs the higher octane it's not good and will cause knock. But otherwise you need to use what your car is recommended for otherwise you will run into problems in the long run. For ex. running anything higher on our car then 87 will cause buildup because it can't be burned fast enough.

matteichenfels

....It says right on the window sticker when you buy it new...87 octane... if i'm not mistaking it also says that in the handbook.

Light_Speed

it says to use 87 octane in the handbook

Bluesman

What is wrong with you people are you unable to read and comprehind ( understand)???????

ju5tchi11in

do those fuel system cleaners that you pour into your gas tank clear the build up from those higher octane gasses?

cabbages_baby

damn ive been using 89 octane...guess ill switch to 87 now. should i wait till my tank is almost empty to switch or can i go ahead and refill my tank now, which is half-full with 89? or does it matter?

CLpower

cabbage, it doesn't matter

JCL

Read this article....

Don't believe anyone but what the manual says to use and that would be 87. A higher octane should only be used if you hear pinging in your engine and even then I would only put it in once every 4 tanks.

ib_jimmy

i know our car manual and everywhere else on the car recommend 87...but i do feel a different with 93....its seem to be more responsive and smoother.....is that true or am i just getting high of that high octane?

So my question is will high octane in our car run better even if it does cause problems in the future?

CLpower

no, you have a 3.0 right? As I said, it's been dyno proven that 87 has more power then anything else. If you have a 2.2/.3 I'm not really sure, but I wouldn't waste the money.

ejammies

Actually it will probably run worse. Acura has all the timing down pat for the octaine that the car is supposed to run. I have NEVER ONCE put anything in my car but 87 and I tell you it runs just as smooth as it did in 1997 when it came off the lot. If you think it does good then by all means do whatever floats your boat!

lowpost

I agree - although it could be psychological. But my car seems to run smoother (not faster) on chevron 92. on 87 my engine feels rougher. It could be the difference in additives (chevron only) and nothing to do with Octane.

ALso 14hp is a LOT to lose from using 92 as opposed to 87. I'm not questioning the C&D test but it may not mean much in real world driving conditions. I know my car really well and I have never felt that loss of power on 92, and I drive my car pretty hard. If anything, I neither gained nor loss hp, but the engine felt smoother.

CLpower

it's been proven on other dyno runs before too, not just w/ C&D.


Your car physically can NOT burn anything other then 87 fast enough to prevent clogging, and buildup, etc. The car is not set up to run on anything other then 87. ANything else is completely and absolutely pointless and makes you stupid for using it. I don't know how else to get this information into your guys head. BUt hey, if you don't want to listen to me don't worry about it. Go abouts doing what you do

AcidFire

OK, here is a question for you all.

Does anyone know how altitude pays into all this. Our gas here in Denver, CO goes 85,87,91. I know at lower altitudes it goes 87,89,92 or 93.

Would I be right in running 85?? I have been running 87, but if 85 will work, I would rather save the cash.

Thanks

Ok I got a ? now, since I am running Nitrous I will need higher octane right? The NX kit actually reccomends adding octane booster! So with my VAFC and NX I would need the 92 octane wouldnt I?

CLpower

Yes, when you are going to use the nitrous you need to have 92 in the tank. But when just driving around town i'd use 87

ib_jimmy

ok my car is low on gas...imma go fill it up with 87 after work. I remember the last time i did that....the engine noise sound lower...like its moving slower.

CLpower

also try an injector cleaner while you are at it, it's not a great fix, but it'll do for the mean time till you get the professionally done. If you've been running 91-93 for a little while they are most likely pretty clogged w/ build up.

clracer97

i guess i should run 87 on my 3.0 although i am still a little shaky since my family uses 93 on all their cars. but if 87 will improve performance on my car and wont cause buildup in the fuel injectors, then i guess i should go with whats better for my car.
