nitro fuel

[97cavalier]

Hi i have a 97 cavalier rs, and i have heard somthing like this in other threads. I have gas for a rc truck and it is 20% nitro. I saw in other treads that you could put like one cup or so of this in your gas and it will run alot better and boost up you octang alot. Is this true, and if so will it hurt you motor? I know you can just buy octang booster , but i was wanting to know if this will work?

Why would you want to raise your octane? The higher the octane, the more resistant to predetonation the fuel is. Your Cavalier, unless running boost or nitrous is supposed to get the 87 or whatever, raising the octane too much wont do anything but make the car run a little under par and potentially hurt it.

Not to mention burn hotter potentially causing damage over long amnts of time.

"whatcha talkin' about, Willis?" <gary coleman>

higher octane on a normal car that takes 87 will not make the car run hotter; it'll just run richer...

i think, u mean if it runs leaner> then it'll get hotter> bad fo engine.

but carbon-deposited old engines can temp benefit goin higher octane as a temp solution to predetonation, but u really should look into seafoam or other carbon cleaner to stay @ 87 octane levels.

Well you always hear you run more octang and it runs better, and race cars run higher octang fuel. like racing ruel. It makes there cars run better

Well in a sense it does make them run "better", but not in the sense that they have more power. Racing cars require higher octane due to the circumstances that they are running at. Very high temperatures, high compression, turbo/supercharged, advanced timing, etc all can lead to pre-detonation (knock). The higher the octane level, the more it resists igniting prematurely.

cdru, i agree w/ u... only if you have an engine that has turbo or highly modified engine that u need a higher octane gas... otherwise that is a myth that u are falling for 97 cavalier, unless u got some carbon buildup in the combustion chambers, which will cause predetonation...

i've seen sis' cavalier 2.2l owners manual & it states u should use 87 only... goto jbody.org forums & they'll verify what i've been saying

Racing fuel shouldn't hurt your engine, unless you get 110 octane which has lead and will make your cat useless in minutes. 87 octane means 87% octane, the other 13% is septane, which will detonate under compression, in the right conditions. Octane will not detonate under normal compression. 100 octane actually burns cooler, slower and more completely than 87. Hmm..., if only we could afford it!

Nitro Methane is a whole different story, seeing how dramatically top fuel engines blow up, I wouldn't put nitro in my fuel.

Yeah well, I have to use 93 in my car under any circumstance can I go below 91 in it. And 93 is the minimum available around here that is over 89..

My 2 cents.if i use anything below 91 oct, my check engine light goes on, and i get less power. Now on my parents cars, this is also true. Also, if anything, you will get better gas mi. If you always use cheep gas like 89 oct, you WILL get alot of carbon build up. now, you can use 89 oct for a month or so, but every so often use the hi test. Just my 2 cents.

ok for the final time in this thread,

Higher Octane does not burn hotter
Higher Octane does not give a NA car thats supposed to run on 87 octane more power.
Higher Octane gas does not give you better gas mileage
Higher Octane gas does not have more cleaning agents in it
Lower Octane gas does not cause more carbon build up than higher octane gas
Higher Octane gas is harder to burn

If your getting a check engine light because of low octane gas, you have a problem with your car.

Octane does nothing more than resist the gases ability to spontaneously combust inside the cylinder before the spark ignites. THATS IT! YOU GOT IT? NOTHING MORE! Higher octane gas is for cars that have a high compression ratio, stock cavaliers dont have a high compression ratio. You will need higher octane gas when you start getting into 11:1 and above compression.

IF YOU BELIEVE ANYTHING ELSE, YOU ARE RETARDED!

Keep running cheep gas in your engine, and see how long it lasts. Rock on!

vamc, u r falling for it, just like 97cavalier... if your check engine lights up when u use the 87 octane, is it because the owner's manual says to use higher octane gas? what year/make/model is your vehicle?

did you run a trouble code test to see what the car's pc has stored in it's memory while using the standard grade gasoline? <please note year/make/model>

u got the placebo effect or you don't do the carbon cleaning process like using seafoam every 2-3 years.

i'm running 87 octane in my 1989 nissan 240sx & the emissions are way in the green/just like from the factory because I've kept up w/ preventative maintenance <oil/filter changes>. since I can still move my distributor to advance timing, sure, i can use higher octane to compensate & get a bit more power, but I won't since the mileage of the engine <204,ooo> might not take the added abuse & i'm getting 25 mpg outta this old daily driver of mine.
