jus a quick question.... i have a d16z6 108,000. wat is the highest octaine gas i can run SAFELY?!


jus a side question my buddy wants to kno.... the redline is 7200... wat the highest shift he can go without shortening the life of the engine?

you can actually run pure alcohol in this engine because it was cast from high grade iron/titanium alloy mix, and you can probably rev it to about 7800 without hurting it, the numbers in the book just plays it safe

i dont NEED high octane.... i thought that if there would be no problems that it was an easy way to pull a lil more power.... i jus run 93 in it now.

but i take it wit ur reaction its not a good idea to put 100-103 in??

High octane fuel that you get at the pump isn't going to get you more power it is just going to waste your money.

As a general rule of thumb high octane does not make power it supports power. An octane rating is the fuels resistance to detonation. This will not help you to make any power, it will simply support the power by not detonating under high combustion chamber pressures.

thanks CRX and Dragon... thats the kind of answer i was lookin for.


u guys kno wat a safe redline is though...or more so the highest safe shift

ON A STOCK MOTOR IT WOULD BE THE STOCK REDLINE. FOR HIGHER REVS DO YOUR VALVE SPRINGS

Oh really?

Tell me more.

Well, basically you gain about 6 horsepower for every level of octane above 87. Now you just have to ask yourself, "how fast do I want to go"?

Looks like I'm going to fill my gas tank with 2,000,000 octane fuel. Thanks

Only do it with a SOHC VTEC engine! If it's a DOHC VTEC engine then it'll explode when the high-cam engages!

i run plus on my d15b7 89octane i think? anyways and every once in a great while i'll put supreme in, it hasent hurt mine yet, i honestly dont think it will.

speedooo

octane is gasolines ability to resist burning...basicaly octane eliminates pinging/detonation found in high compression motors. running a higher octane in a stock motor does pretty much NOTHING and running a lower octane is the only way to hurt the motor

ive been told by more then 1 tuner and honda builders that DOHC VTEC should run on 92 octane and nothing lower.

i dont see a PREMIUM FUEL ONLY sticker on pre k series honda

dragonfly2k3

They say this because with the vtec system it extends the intake valves timing introducing more air and fuel into the combustion chambers. More air/fuel in the same size area = more pressure. I run 89 in mine and will continue to run 89 until i boost.

My EM1 has one near the gas cap.

Also, premium where I live is 91, no problems.
