LOL **** v-tech it sucks.. MIVEC owns

 

Don't forget the Folgers coffee can at the back end, that and a Type R sticker should be good for about 5 hp..

oh duh, what a dink I am, where the hell are ya going to get 110 octane unleaded fuel... lol good one, had me there..

 

When I first got my RA I experimented with high octane gasoline and found that I got the same gas mileage with 92 octane and 89 octane. I guess that is not really your question, but it may halp...

 

IBTL.....
oh ffs people......there have been several threads about this. SEARCH reveals these:

No need to put higher octane fuel in your engine unless you have a tuned ecu or piggyback ecu with the proper fuel maps.
NO GAINS JUST ON HIGHER OCTANE GAS!
Put higher octane in without proper tuning or higher compression where the higher octane is needed and you are wasting money.

 

This is also a pretty good read if you don't understand octane.

Yea, I understand what you guys are saying but I dont know why I can really feel the difference on throttle response between 87 and 91 V-power octane at shells. I dont think it can improve the HP on the car but my point is that it seem to have better throttle response especially when I had my CAI installed. Not super great difference but just a little better throttle response, enough for me to feel it though.

 

^^^it's in your head. Seriously.

Someone talked about having a datalogger to prove otherwise, but never posted any verifiable proof.
Higher octane needs higher compression to burn properly and completely. Using premium over a long period of time not only drains your wallet unnecessarily, it may cause your valves to gum up over time from all the gas that was not completely combusted.
