93 octane in N/A motor.

[Shift_Alabama]

LOL u guys are e-thuggin over pump gas.

AARGH! Thread pirate!

[Kckouki]

i had a full time job

Ok and, I have a ****in job to. Im workin with my bro and some of his freinds doing landscaping.

I get payed, I pay for my own ****.

kckouki,

dude, you cant even drive w/o someone in the car, so this doesnt concern you okay ***?

Im not allowed to cut down nico members anymore, but belive me this wasnt warrented...just because hes on his permit doesnt mean he doesnt know anything about vehicles, so keep your negative opinion to yourself.

[cmfireman]

haha, RETodd is mad that he got Pwnt by KC.

EvilE-thugg is mad because I burnt him in this thread:zerothread/224381

Run whatever the **** you want to in your cars. I'm sticking with 93.

/end E-thugging

I think this is the only "pwnt" comment in the whole thread.

[neverlift]

in stock form e motors benefit from high octane,but are less sensitive to the change up then a de with knock sensor. just thought I'd throw that out there.

I normally link to the pertinant information, but ONLY if the OP meets these requirements:

Has a post count <100Seems to have some clue on what he/she is talking aboutPresents his/her question in a acceptable form, Not "Yo dawg, where can I find these mad-tyte wheels"Uses proper grammar

If you've been here a while, create a pointles THIS VS.THAT thread,are an a$$, have no clue what you're talking about, or have created many absolutely pointless threads....

You don't meet the requirements.

I'm running 93 in my KA, but my timing is advanced so I need it. I would still run 93 even if it wasn't though. I like having peace of mind about my cars.

[hpmachine]

I suck my moms tits, my parents pay for everything for me, my mom makes my dinner, and I put 87 and 93 octane in my car both at once. oh I gotta go my dinner is ready. my mom made me a grilled cheese sandwich

Yup, you really ""pwnt"" me there. Damn, you got me.

[Logan76]

Everyone just stfu, seriously so what if hes 15, atleast he has a nice car and cares enough to take care of it, unlike most of us when we were 15...Im tired of the sensless arguing...this threads full of it.

[karmapolice991]

BTW running low octane can cause spark knock which in my mind is worth the extra $.50/gal simply cuz its annoying as hell on a drive longer than 10min. I guess it can damage your engine too. I've never really heard of anybody losing an engine over it but its prolly one of those small problems combined with numerous other small problems that ends up in something breaking in a +10 year car.

[1CLEANCOUPE]

I put 93 on my DOHC all the time. previous owner used 87 and the car ran like crap.

My g/f puts 93 octane on her SOHC. Everytime that she had put 87 octane, the car made weird noices when accelerating hard.

And I think is good for your fuel system anyways

I agree Logan. I was simply stating that I thought the KA24DE was supposed to run on mid-grade or premium fuel.

Somebody had to be a smartass so I posted the picture.

Then Evilwashyourass started in on me with his post count of 25. Ban evil, problem solved.

I'm finished with the pointless arguing here, and have no hard feelings with RB25DETodd, I just thought what KC said was funny.

I dunno about your car, but my owner's manual says to use premium unleaded 91 octane or better...

The fuel door just says to use premium, i use 93 octane in my car; bottom line is that you will get about zero performance gain, but performance is not always the goal when buying quality fuel...

it will live on 87, if you can afford it get at least 89 in it... and dont forget TOPTIER!!!

[S3t0_S13]

hmm, i always run 87 in my 92 KA, rarely 91 or 93, i didnt know advanced timing needed higher oct. though

[SPIRONIUM]

it will live on 87, if you can afford it get at least 89 in it... and dont forget TOPTIER!!!

I strongly believe that "yellow" gas vs "clear" toptier gas is just advertising. After opening up a 210k motor that has been fed "yellow" gas by my family since 1989 and finding the internals to be in tip top shape for its age, no excessive carbon, and it never leaked oil past the valve seals i have since come to the above conclusion. I understand how unscientific it is to inspect just that one motor, but it had surprised me enough. The frame of the car was trashed for rusted framerails hence why my curiosity had to open up the motor.

Somebody had to be a smartass so I posted the picture.

the 89-90 manual says 87 and nothing more, i was misinformed about the later twin cam years, thanks for being a d!ck

[S3t0_S13]

someone told me, that the KA should stick with 87, and if u run 93 too much, it burns "too clean"? and it will damage your internals???? wtfsomeone correct me

[babowc]

meh..i used to run 93..im running 87 now..there is not a big difference whether you run premium or regular on a stock car..stock = no heavy modifications.

sure, factory suggests you to run premium.. not a whole lot of difference, IMO.

i run 87.. it feels absolutely fine to me.ill be running 93+ when i boost~

[S3t0_S13]

ive heard, that if ur car isnt told to run 93, then you shouldnt run 93, you might damage something??

[R6_240sx]

Hey Seto u kno that in other states 93 is still pump gas right?

Us CA ppl get 91...

Anyways if ur car is stock just stick to filling gas at the pump (which ever gas floats ur boat), no need for higher grades of fuel or octane boosters that stuff is caca.

[adrianfromthecastle]

this thread needs more boobies

[redtop91]

RB20DETodd that was uncalled for. To the OP: My question to you is why not? It might not help but it certainly won't hurt. I ran 87 on my SR once .

[nzmoman]

there is zero reason to run anything higher than 87 for an NA ka, if you feel benefits from 93 octane it is your imagination. But if that makes u happy go for it. Search google for some tech articles or something if u dont believe me

running higher octane is not mandatory it is recommended. the reason is because the car will ignite the fuel better as stock KA's are tuned for it. The other alernative is running lower octane and adding booster, which will help. It depends on your personal preference. my car gets better gas mileage on premi

[ricebike]

someone told me, that the KA24E should stick with 87, and if u run 93 too much, it burns "too clean"? and it will damage your internals???? wtfsomeone correct me

it doesn't burn too clean; higher octane burns "slower" so it's more stable...

there's a mixup between the SOHC ka24E vs DOHC ka24DE on this thread: Seto, must re-read them.

SOHC ka24E: manual says 87 octane, but most of the engines w/ high carbon buildup would start to ping, hence bumping it up to 91 may help for a bit. 93 octane may be too slow to burn & might cause excessive carbon buildup.

SEAFOAM may help clear this out to start using 87 octane gas safely again... no knock sensors on these mofo's --soo better b safe than sorry! --------------------------------------cliffnotes on the DOHC ka24DE: "premium" or midgrade is recommended @ least 91 octane (as others already mentioned) but can get away w/ 87 w/ the knock sensor retarding the timing/losing a bit of power/mileage too

the end

[oki_bum]

93 octane FTW!!!!

I dont care what anybody says...theres a noticable difference when running 93 over the lesser, and i dont mean the difference in your wallet, cuz its not that much anyways (a few dollars in the end). My old KA idled smoother and gave noticable power with 93. Definitly makes you throttle happy!

[StuckChuckSC]

I thought I read 91 AKI in the '91 owner's manual I have. I'd look it up if it didn't seem pointless to me.

My DOHC runs strong with 218,xxx miles. I ran up the last 30,000 miles with 91 AKI. I do fuel injector treatment once a month for piece of mind. Will prolly seafoam when the swap is done (dropping DOHC into '89). Best advice I have is to be CONSISTENT about gasoline use. There's no point in teasing the knock sensor; she be a harsh mistress. But I was informed by the dealer when I first got the car that it's entire life had lived on 91 AKI, and I didn't want to upset an engine that had found zen.

Buddy has a '91 240sx fastback that he always dumps 89 in. Though his engine has 50,000 less miles on it, he's already hit the timing chain problem. Stab in the dark that knock sensor retarding timing advanced timing chain degradation? His car was also m/t with Hotshot(?) headers and exhaust, if anyone thinks that made a big diff in his timing chain ****ting out before mine.Mine's just stock a/t, FOR NOW@!#$%%$&@#%*&

damnit, typo FTL, i was asking bout DOHC, as i have one, i think ill stick with 91 and sometimes 93

[greengt2nv]

Well now. I run premium once a week to clean it out and get a little more mpg. I have tried the acetone thing and it works. people say that oh acetone doesn't do ****. well yes it does you ad 2 oz. of acetone for every ten gallons. if you run more than that its at your own risk. but it works the best in boosted vehicles. my buddies civic was crazy on the acetone added. Acetone helps clean the system kind of like sea foam but without all the smoke. just my .02 if anyone cares.
