does anybody know if this is bad for your car,or how good is it for your car.and will i notice a big difference from 94.

 

where the hell in ohio would you find 110,....i dont think it would be good for daily use,..and it would be to expensive

 

you can get it online...i know

or maybe if yall have a local drag strip

 

there is a place in milford by where i live and right by the drag strip im going to next week i only want to run it at the strip

 

Another octane thread. The octane rating on gasoline and gashol has nothing to do with how much power your engine will develop running them. High octane fuel (93+ or 91+ depending on your state) is used for IC engines with high cylinder compression, knocking or pinging problems, or to prevent early detonation.

Therefore, the Honda-Acura cars that require High octane are Integra GS-R/TR, S2000, Civic SI, Accord V6, NSX.

You will not notice any difference in power, because there will be none in your naturally aspirated, low compression engines. If you change your cylinder compression, or add a turbocharger, or experience engine knocking, use the higher octane fuel - your owners manual will tell you also. In that case, running 87 or 89 octane in cars that require high octane will exhibit a slight loss of power - this does not go the other way around.

BTW, you can get 'Octane Boosters' from any auto part shops that you add to your tank before fillup.

 

98-02 av6 uses 87. the odessey makes more power using 91, less using 87

 

i have 2k si and im pretty sure it has high compression like 10:2:1 or some thing like that and i know there is a 5 hp difference between 91 and 100 octane

 

Higher octane fuel does not equal more power. Higher octane fuel is simply harder to explode. That means it takes a more powerful spark to actually get it to ignite (which most ignitions are capable of) but is harder to detonate (which is exploding where it's not supposed to, like before the pistons comes back to TDC or in the intake manifold). Some higher compression engines run better on higher octane fuels simply because they could get detonation on lower octanes. For example, a GS-R's B18C1 DOHC VTEC engine. It has around 10 to 1 compression and very aggressive fuel and ignition maps and requires premium fuel. It also has a knock sensor that listens for detonation and will richen the fuel mix and pull some ignition timing out if it hears any. That's why it makes less power on lower octane. Not because the fuel has less potential but because the engine is trying to keep from destroying itself. Seeya.

 

i'm pretty sure the RSX-S and CL/TL-S have to use it too. I use 93 octane, but of course i run 7 pounds of boost daily

 

i HAVE heard of cars making more power ON a dyno with race gas.. now i TOTALY agree with what was stated about octane and it JUST being resistance to detonation, but why do some cars show slightly higher numbers on better gas.. please refrain from saying something liek "you are a liar" or "show me the dyno" im NOT saying its true.. im JUST saying ive heard it MANY times MOSTLY from domestic tuners..
