What Octane Fuel do you run in your 3gee?

[Tomisimo]

I run98-octane. 95 is for korberetors... for EFI 98 warks fine.

[Legend_master]

I run 93 ever since the motor swap.

Ok, here's the real deal on octane....
http://www.oregon.gov/ODA/MSD/docs/p...tane_guide.pdf
And for reference, all grades of gasoline have the same or close to the same amount of energy per liter.(some high octane fuels have additives that increase energy/liter) Octane has nothing to do power, however it does influence how you set your timing/compression and therefore is relative to power.

[Tomisimo]

dont know man, but i feeled a BIG diference when i started to drive on 98octane insted of 95.
edit: and fuel consaption went down to. Propably coz of motor needs las RPM to klime hils aroud here.

[speedpenguin]

I ran 87. You don't need anything else unless you have a cam, or you bumped the timing.

[88LXi68]

Depending on where I am 93-110

I run Chevron 87 , and have not noticed any pinging .

But... My original owners manual states that I should run 91 . I will have to give it a try once I have some extra $$ . and see if I get better MPG with the 91 .
My car idle pretty well 90% of the time . Sometimes at stoplights , it gets a little rough .

[etvergara23]

i run 87 oct as well.

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.

go read Frantik'S post, our 87 is equivalent to 91 RON. There is no benefit in using 91 octane in those engines in stock from.

[AccordB20A]

91 octane with some shel fuel economy formula. makes each take go a bit further.. and i swerar by it.. IT WORKS!!!!!!!11111!!1one!!!!!!!111!!eleven

go well go shell

[buttaz1]

i run 89 cuz i never have enough for 91 or what ever and 87 aka the chepo gas sucks it waste too fast like if i put the medium gas i can drift about 15 miles before the needle moves. noticably. and with the cheepo kind i cant get in my car befor the neeble goes to empty?


also what chhick broth is that like chiken juice purred down the carb

[HondaBoy]

i'm using 93 octane now. after taking all the vacuum crap off it would ping in our hot weather. gets between 20-35 miles more a tank since i consistantly started using it, of course depending on how i drive it. idles smoother, exhaust note is a little different too, but in a good healthy sounding way. dont know why that changes when i go from 87 to 93 octane? anyway, high humidity and hot air dont help with the pinging it was getting. i'll probably use 87 octane after i do some more tweeking if i can get it right. oh, and the engine runs cooler with the use of 93 octane, but its always hot here so any bit helps. just what i've observed over the 3 or 4 months of using the 93. but yeah, not everyone needs to use it.

[mkymonkey]

we even run 87 on our tow trucks....the cheaper the better

[buttaz1]

does that octane booster stuff really work?

[Legend_master]

does that octane booster stuff really work?

it really boost octane , if thats what you mean.

[Cheeseburger]

ya do they work????

[mkymonkey]

not really, at least not according to the news, magazines, and some speed shows

[MessyHonda]

not really, at least not according to the news, magazines, and some speed shows

i guess thats how they rip you off...

[mkymonkey]

yeah just a waste of money....they dont even supply better mpg like they say they do

[MessyHonda]

yeah just a waste of money....they dont even supply better mpg like they say they do

leave it to the myth busters....i bet they have done something about MPG but that was on like A/C with the windows down...or the tail gate up or something like that.

[mjv13]

87. Cant find anything any lower or cheaper!

[snoopyloopy]

does that octane booster stuff really work?

yes, but by time you buy enough to actually say boost your octane from 87 to 89, you could've just filled up with 91 insted.

[Toneloc5145]

I use 87 octane, and I try to buy shell gas if possible. I tried 89 once, it didnt make a difference at all in power or economy, but the engine sounded a little different.

[Steve_Si]

My stupid F20B DOHC has a stock compression ratio of 11:1 so needs all the octane it can get

Having said that, it runs perfectly fine on 95 RON. Probably cause I drive like an old man and don't rev it past 3500rpm, 2000 below the vtec kick-in. The H22A wagon was on 91 RON but I found it would get 10% further on 95, which only costs 2% more. Neither car gets any further on 98 RON.

I always ran my B20A cars on 91 RON and had no problems.

[Tomisimo]

NO... dont get a idea to spend money on that shit.
