What Octane Fuel do you run in your 3gee?

[forrest89sei]

just wondering what octane fuel you guys run?

I run 89 (In California)

[A18A]

91, its the only 1 we got here, and isnt there already another thread about this? :P

[snoopyloopy]

california 91 octane from the 76 station on the corner of anderson street and redlands boulevard in loma linda, california.

i was runnig 91 till i made the trip to maine wich i knocked it down to medium grade to save some cash on the trip, then when i got here it broke down so right now its getting fresh air only lol

my mom would run 89 on the dx ever since she got it.....later the car did not run right and we would put 91....it did not help...it was all in my mind. anyways...now that i work....i put cheap gas in....87.....i just heard that i should put some seafoam....so it can clear up all that build up...anyways ima go get some tomorrow maybe pick up a claybar kit.and wash it so monkey or legend can make me a sig.

87 octane. The lower the octane you can run without detonation, the more power you will make. Higher grade gas does not make your car run better unless you have an OBDI or OBDII car with a knock sensor that retards the timing if it senses octane ping. All octane really means is how volatile the gas is, lower octane, more volatile, meaning it will combust sooner than a higher octane fuel will, effectively advancing timing just due to it's easier to ignite nature.

High compression engines need high octane fuel because it's combustion is easier to control, meaning it wont ignite from just compression and heat alone, the spark of the plug has to be it's source of combustion.

<<<< cali 87

just in my defence lol i have bad pinging whenever i give it more then half open, and timeing had been checked over and over, just depends how lean you run aswell wich seemed to work out for me running leaner with more octane, just deffending myself lol

when i switched from 87 to 91, i didn't notice that much of a difference. it wasn't like going from a car limping on 3 cyl to a perfectly purring vtec motor. but it was noticable, mostly in the car running a little smoother. and i also got an ever so slight increase in mpg.

The stock A20A is designed to run on 87 octane. OD, you have 91 there cause they use the RON method calculation. Here, we have RON+MON/2

I use 87 octane in the A20A and 91 in the B20A.

[BITESIZE]

It's had the same 1/2 tank of 87 gas that it had in April...

[frantik]

87 ftw!!! no need to spend extra money on octane that the engine doesnt need

[3ghondaerodeck]

I run 95, in Holland we don't go lower, every ones in a while I go with the shell V-power that's 98 (whenever I'm in Germany I go with the german v-power that's 100 101 I think)

[GhettoNoodles]

I run 8 oz of Chicken broth with 87

i heard you get like 45mpg with that....and your car smells cleaner...kinda like burning vegi oil on a diesel

huh? i googled that but didnt really find anything helpfull

[GhettoNoodles]

nothing like chicken down the carb!

wikipedia is your friend

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel through a specific test engine with a variable compression ratio under controlled conditions, and comparing these results with those for mixtures of isooctane and n-heptane.

There is another type of octane rating, called Motor Octane Number (MON) or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally fuel specifications require both a minimum RON and a minimum MON.

In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-95 (regular) in Europe.

I run 87 octane. No point in running anything else like RamThis said its just a waste of money to run anything else. Bare in mind if you turbo your motor or whatnot, then 91 would be a good idea... but on a pretty much stock a20 there is absolutely no reason to run anythin more than 87

[Civic Accord Honda]

87 unless there out then i get 89 if we got 89 in my old accord it got 45mpg but it really stunk and smoged all up in here

you guys should send me a few barells(sp?) of 87... lol and heres me thinking i could just water down 91 to a lower octqne :P

^ did u see my post? your 91 is our 87

[A18A]

^ did u see my post? your 91 is our 87

ergh i just saw it now, i guess i should hit the refresh button before making a post

your gas is still cheaper than ours though

[carotman]

^ did u see my post? your 91 is our 87

My Owner's manual even says we have to use 91 Reasearch Octane Number in the Accord I guess they didn't know we don't use RON numbers in Canada.
