maybe it was just psychological, but when i filled with the middle grade gas (as opposed to my normal fill of the crap gas), my cl ran a little faster. it's '97 2.2 . So i don't know, what gas should i use for my car?

i use 87 octance (regular) 90% of the time, once in a while i use 89.

87... runs just fine for me.

this is a giant btw.

93

weedahlong

what do those numbers mean? 93 . . 87 . . .89??

CL Platano

for the 1 millionth time, use 87 octane (regular) grade gas, its what the car was desinged to run on, anything else is a waste of money.

search if you want to hear that a few thousand more times

91 for me. because i have a lot of miles

omg

98 CL

i know it's a good idea to use 87 on our cars, but what about on a car with mods, like cold air intake, headers, etc? Any change? ( i was reading to use 92 or 93 for cars with forced inducton. What's this?

I use 93, I feel that it burns cleaner, and gives out a bit more gas mileage. I've been using 93 for years.

bkmc24

ive been using 89 everytime i fill up and its been good to me but w/e you do stay with one octane cuz if you decide to go cheap and buy 87 afetr u used 93 or 89 your car will run shitty for a while cuz it was used to the higher octane

let the tard-fest begin.....

wow, you guys aren't very tolerant of noobs in here. thanks for those that helped.

Musulsa

So much false information on here.... it boggles the mind.

I'm looking at the ages of some of the posters... they haven't even taken basic chemistry yet, and it shows.

Chinisimo

bolt ons doesn't matter, just use regular 87. forced induction means turbo/super charged or running NOS

mongose99

Ok. 87 is fine for honda/acura engines everything will run the way its supposed to. 89 gas will enhance performance because the combustion will be slightly more powerful, therefore meaning that an increase in power will be made.... although its not always noticable. If you choose to run on 91,92,93 and so on gas you need to be aware of the fact that the explosion in the combustion camber will be more potent, that is the explosion will be hotter and more powerful. This is good for forced induction motors or high compression motors that are built to handle the added heat and pressure. A stock motor will be able to run on these higher octance gases, but will be at risk because of the more powerful and more importantly the hotter combustion. This can lead to premature wear of engine parts and can be more harmful than helpful. Hope that helps.

ajtcl

Don't let these guys get to you... It is just that they have all asked this question at least once since they joined. I use 89. I have a few mods... And I figure wtf. 87 is cheaper though, I almost bought it today, but the Mistress had a fresh wash and was looking real good, so I couldn't feed her cheap fast food.

Hope you'll stick around, just read the threads and search. A lot of stuff has been covered... and you might come up with one they haven't heard.

so true, so true

sweeeet, spanks fer the info guys. ill stick el cheapo gas . . . considering the insurance and car payments alone, not to mention food, books, costoflivinga ;fsdjkasf

nother question . . .

if i reverse, then put it back into drive, theres a weird gear jumbling sound . . same happens if i'm goin from neutral to drive. something i should get checked out? oh . .aaand, the breaks just started squeeking a little, i assume i need new break pads right? i had to get new rotors for my old volvo but i hope i dont' have to do that for this car since i detected the wear quicker.

mongose99

Most brake pads have a "squeal strip" or something like that will squeak, squeal, be annoying, whatever when the brake pads have been worn down to a certain point. Its put there to tell the driver the brake pads need to be replaced, so yeah soon you'll need to change your pads. Your rotors may be ok still, it all depends on how worn down they are, once they get worn down to a certain thickness they are deemed unusable. Usually they'll be fine and will need to be resurfaced rather than replaced.
Just a quick thing on the transmission. Im assuming its auto, cause that just makes sense( you said you put it in drive). That noise would be the sound of your transmission switching internally from one set of gears and bands to another. Basically, you either haven't changed your tranny fluid for a long time or your transmission is slowly dying. Either way have it checked out.

weedahlong

wow, deeeep. spanks mongose

LCARUCA 97

its been dyno proven that 87 runs the best and on top of that its what the manual calls for. anyone that says they are benefiting from anthing else is a fucking moron. sorry to piss on anyones cornflakes here, but thats how it is and its been covered so many times that we should have a popup upon entering the forum that says "our cars use 87 octane ONLY!"

mongose99

Not to really argue, but the book also never mentions modifying your engine. Increased airflow and/or spark will require either more gas or a higher octane, otherwise you'll run lean. If honda/acura engine ran at maximum performance on 87 octance, then racers and builders would not use any other type...just 87. Its physics. Higher octance = more combustion.
I will agree that a stock, unmodified engine might not benefit from a higher octance gas, but a modified engine will. And not to call you out or something, but if you do have dyno proof that 87 is better, please let me know. Im interested to see.
This is the factory reccomendation based upon gas milage testing, engine life, and other standards. You can use other octanes. If you really think im wrong, please let me know your understanding on this topic. Im always open to learning.

shineynitelite

nitromethane seems to do the trick

agranado

fuck man stop pissing on my fucking corn flakes I use 100 octane ALL THE TIME and I get at least 20 extra ponies from the cleaner fuel being sparked and running through everything.

im a pathological liar

Motohip

Not to start an argument or anything, but...

In the manual it says to use at least 86 octane. That is all it says about recomended octane. Also, dyno runs are usually at WOT which I'm sure makes a difference. I would also like to see dyno proof. You should also take into account that not everyone lives in the same climate or altitude. Just throwing stuff out there...

you are supposed to use the lowest octane possible before knocking occurs. and bolt ons don't mean shit either. its about compression and timing. the lower the number of octane the more energy there is in the fuel. just do some reading and you will see. and if not just continue wasting your money.

LCARUCA 97

unless your car has a turbo or sc you will never need more gas, our fuel system is already over-powered as it is. and people that race generally have some sort of FI which means the compression and/or the timing will be more than normal. octane has nothing to do with being more potent or cleaner, there is a choice at the pump because there are lots of different types of engines.

BlueCLRycR

at LEAST 86. the higher the octane rating, the more it can be compressed b4 it combusts on its own. meaning if you used a lesser octane of say 84, the fuel would spontaniously combust before the spark plug even ignited. its kindof like your car is prematurely ejaculating. using a higher octane wont hurt anything. of course its not neccesary so basically your wasting your money. unless of course youve done something that increases your compression ratio, turbo, supercharger, etc. intakes and fart cannons dont count. if you have a CL with a turbo and are still running 86, then your fuel could ignite before it even gets into the combustion chamber and that could be potentially deadly(due to explosions and other bad shit like that.) anyway im off tomorrow so im going to go get drunk. later.

ajtcl

Yes, definately check the transmission. These cars have week OEM factory transmissions. If you haven't stayed up on the fluid changes, you may have big trouble in little servos. And, if your transmission has started to slip... Forget about it... You are already too late.

Good luck.

LMAO that does seem a little off the wall if you havent read the whole thread.

mongose99

Ok, good info there. Like i mentioned somewhere before many of the engines i own/build are high compression, which is why i use higher octane fuel. Apparently some of my reasoning was a little off though. thanks for the info

ajtcl

Sorry guys, missed the second half... Oh, and piss works the same as beer in my corn flakes. FUCK IT. I'm gonna go for a lead-footed drive to the pump and fill up with 97, then poor in some fucking octain booster so my shit won't ever DESAL. JK

Peace... just lost my head or something. Still using 89 don't give a rat's ass about the price... just makes me feel "warm and cozy." And as I said, The Mistress was looking good and I just couldn't feed her that cheap fast food.

LOL

weedahlong

shoot . . . any suggestions on what transmition fluid to use? and how much? and is it like an oil change where i unbolt something from the bottom?

ajtcl

Honda ATF... every four oil changes, or once a year. Have it flushed, or do a drain and fill. It isn't hard to do, but why do it yourself. You still gotta get rid of that toxic-ass shit. There are roughly 15 quarts, if I remember correctly. Can be costly to do yourself.
