87 in the accord. I got more carbon buildup running 93 octane. i had to change my spark plugs and clean out my EGR valve. It cleaned out my injectors tho. I actually saw an increase in MPG running 87 vs. 93. 89 is the most i would run in a low compression motor. BP gasoline FTW BTW
87 in the civic now, before 89 when it was cheaper
I Took my motor apart recently I pumped 93 most of the time.I had a whole lot of carbon build up on the pistons.

87...
premium only... 3000gt
Cause 9 out of 10 times your car was built to run on 87 octane. Unless you're runnin a B18C or an H22A you dont need it. The rest of the honda motors are low compression, they dont burn that high octane properly. I wouldnt go higher than 89, but at todays prices its really not worth it
yea I was wondering that but my compression on my ls is up there with a gsr or b16.

I have 3 vehicles...
'86 F150 302 FI 16-17mpg 87
''94 Mazda Protege LX 39-43 mpg 87
'94 Mazda 626 LX V6 27-29 mpg 89 (requires premium)
K series 626. That's right. It's got a K in it.
I myself run E10, 87 octane fuel in my 3G. In the Isuzu, I would run nothing less than 91 octane (turbo, of course that's why I do it).
I would like to run higher octane fuel in my daily driver (3G), but the price and the fact that the higher octane leads to more detonation, which in turn leads to less fuel economy kind of deturs me from the opportunity.

93 cuz better in the long run for your engine
Better for who's engine (Remember to choose words properly before making a fool of yourself)?

93 in the 07' GTI. The manual says you can run lower octane, but it also says to expect bad performance if you do. The Euro GTI's run 95 and get better mpg's.
I believe that most of the car that use a computer to control your car can do some form of timing adjustments. But if your ecu is designed to run 87 max, then it will not advance the timing anymore. Let's say you run like a B18c. If you rung 87, it will retard the timing so much your engine would run like ****.
Naw dont think so myfriend has a gsr and He ran 87 didnt feel different to me

i run 93, sometimes i'll throw in a little STP gas treatment here and there
Very good, man + however many points my greens are worth are worth nowadays. I'll add on to it. All cars nowadays use a computer to do the most advanced thinking of the things we take advantage of. The computer uses sensors to monitor various systems. Dealing with fuel and timing issues, most advanced engine control systems use a knock sensor to listen for detonation. depending on how loud the knock is, it pulls enough timing to keep you in the safe zone and usually when the computer pulls timing, it adds fuel. And that's not usually a good thing. The computer has a preset program in which if it hears knock, it will add fuel and pull timing to keep the combustion chambers from overheating. Usually, if a car was designed to run on high octane, it's because the chamber can't spin the air quick enough at higher speed to make the power it's supposed to make at it's peak power rpm on regular unleaded. Regular unleaded burns quicker than Premium. That's kinda the short of it. There's more to it than just that but that's more or less the basics of it.

ummm...i was told to pump 93 to keep ur motor clean from getting gunk build dups...thats f-ing bull crap...no mater what ur still going to get all that gunk build dup from time to time from shiits going through your intake into IM and into head......from my point of view......if ur compression is low as smuck dont think pumping 93 will actually give u more power on ur rpm band. If your car is a totally high compression motor like 11+ CPR then yes 93 would be a higher octane for a better combustion for the motors performance....!
93 with 25 mpg avg.
-2002 Subaru Impreza WRX Wagon
-2004 Nissan Sentra SE-R Spec V *boosted* (parting out)
well since the accord doesnt have a knock sensor, and its been proven that it runs slower on higher octane, i only pump 87, so it works out. and i have no idea why it runs slower, but there has been too many dynos to prove it.

93...You should all know you get what you pay for. Being cheap costs you in the end...
premium. For better or worse, I'm mapped for nothing but 93. Even 93 with 10% ethanol causes my car to run a touch leaner, and on hotter days, the car will ping. Normally it pings just a bit, but if I try to run anything less than 93, it detonates hard. I learned my lesson after blowing head gaskets, breaking ring lands, and bending two rods in the worst case. Most of the time on ethanol'd gas, it usually just detonates hard enough to break a spark plug or two.
My car is factory....
Every single performance part and or modification it has was made in a factory somewhere.

higher compression motors should run premium gas, also any car that is built should run premium as well. bad detonation means misfiring, rough idle, rough acceleration, etc.
