110 Oct Is it ok ?

[crazy154]

When I am on the way to the track I tend to always want to stop by and fill my car up with 110 octane. Most of the time I go to the track with only 4 bars of fuel. U know how it goes , The lighter you are ,a little faster u will be. When I am running NOS is it OK also to run 110 octane? And i do not mean mix with 93 and 110 i mean straight 110.

should be cool as long as it's unleaded.... it might burn out your cat over time though..

I filled up w/96 octane last week, and I liked it

Cool deal thanks man

don't do it, they do not make a 110 unleaded, only leaded.
it will eat the o2 sensors and cat, also make the car run SLOWER
stick with 93 octane. if need be put 104 unleaded in it.

they got 116 at englishtown and im pretty sure that unleaded i use it all the tim and i had no problems with any of my cars.

116 octane! geez.. 91 is all i get, maybe 94 with octane booster..

110 that was unleaded?? wow that most Cecil has is 104.. 116 is leaded :).. btw leaded gas wil eat your cat and eventually your o2 sensors..

Actually....the higher the octane rating, the lower the rate of burn. Perfect for getting a burn through the complete stroke on a high-boost engine, but not only useless on an N/A, it's actually a slight power eater!

That's why you'll see turbo upgrades for cars (like a Supra in this instance) that say 600 hp on 92 octane, but up to 825 on 100+ octane.

Reason being, the extra air needs extra fuel. But even if the fuel is sufficient for the air in the cylinder, if the fuel burns too quickly, the piston won't be fully pushed down, or will be, but at too slow a rate, causing a knock.

The higher octane fuel allows the piston to be fully pressed down, and at a steady rate. But this is truly only useful if you have the air to warrant it, like on an old big block, or on a highly boosted engine.

Because you're using nitrous, this may allow you to run a bigger shot safely.

But I talked to TRD about this, and they said it's best to run the lowest octane you can without the car starting to knock.

i just looked at sunocos website www.racegas.com and i was wrong it is leaded sry im not a gas guru. but the 104 is unleaded :wiggle: so looks like ill be usin that. would the 116 benefit me when i use nitrous say a 75-100 shot on my stock motor.

high octane is also great for cars running like 14:1 compression or more....cause it burns nice and slow like you said and dampens the chances of knock.

116/c-16 would do you absolutely no good what so ever, don't even waste the 6-8 bucks a gallon for it

the higher octane will help if your timing advance is not limited.. the higher octane prevents detonation and therefore the ignition will be allowed to advance more and more if the knock sensor doesnt get set off. Thats the whole point in using high octane. It makes a higher BTU and burns longer, making the power stroke longer. So if the plug fires earlier it will burn at a good enough rate to make power safely and not detonate......With low octane you can't advance the timing as much because it will make tooo much compression and detonate, because the fuel will react very badly to high pressures.
