just wanting to know if its safe to run my 00 si on e85 daily drives or at the track?

 

What? **** no it's not safe, you need to get larger injectors and a tune if you want to run e85. You can't just fill up your tank and be good to go...

 

whys that...its just like running a higher octane gas.

 

it burns cooler and you make more hp and tq but burn more fuel

 

Except that its not gas. E85 uses about 30% more fuel to run correctly, hence why you need the bigger injectors and a tune.

 

how about E10 blend

 

Whats done to your car that requires more than 93 octane pump gas?

 

nothing...but the 1O% blend is only 89 octane. thats what honda whats you to run. but is it safe to run 10% ethanol.

 

All gas sold in the US at normal stations has a 10% blend, that is perfectly safe. I dont know about your si but mine says to use premium fuel(93octane) not plus fuel(89 octane).

 

It is safe to run E10 because it only has 10% ethanol. Ethanol is extremely corrosive so running E85 could potentially eat away fuel lines and stuff like that... It is not better and you could possibly fail emissions because ethanol emits more hydrocarbons when burned...

 

if thats the case then why is there such a push on getting newer cars to run on e85?

 

Remember back during the gas hike when supposedly it was the over seas oil companies jacking up gas prices?

Well...the government pushed e85 as a way to become more independent from foreign oil companies by using a gasoline-ethanol blend by way of corn...all that did was throw the farming economy out of whack.

He's right, ethanol is very corrosive, over time it tends to eat away at the laquer (spelling?) that insulates the windings of the pump and injectors...burning e85 also emits less btu's than gas...less bang for your buck.

Seeing as you have that massive...10 to 1 compression...i doubt you need something with a higher knock rating...anyone?

Go for it..if you still want it, remember to get it tuned and do alot of research.

I really dont like it period...but that's me.

 

WTF dude, just run premium. You need 91+.

Weird *** question of the century.


No it doesn't. All pump gas sold in the US has up to a 10% ethanol blend.

But yea, it's perfectly safe, like you said.

 

If I remember correctly, ARCO doesn't have any ethanol. Hence, the reason why it's $.05 to $.1 cheaper per gallon.

 

I'm not sure if you're agreeing with me or are saying this to go against what I said. I'm not sure if you realized that "up to 10%" includes 0%.

 

I addressed this issue in another thread so I will just copy and paste my reply:

"Ethanol is only slightly more corrosive than normal gasoline and many people on this board (myself included) have ran it through a stock Honda fuel system for extended periods of time with no detrimental effects on fuel system components. I have read a few instances where after converting to E85, the fuel filter would have to be changed after a short amount of time because deposits in the tank & lines caused by petroleum based gasoline were dissolved by the alcohol and plugged the filter; I personally have not had this problem but it is something to keep in mind. While it is true that ethanol contains less energy per gallon than gasoline and as such requires a higher volume to achieve the same air/fuel ratios (around 20-30%), e85 has an octane rating of 105, is oxygenated, burns cooler than gasoline, and the greater volume needed has an additional cooling effect on the combustion chamber temps. This has the net effect of more horsepower in virtually any application provided you have the proper tuning."

Studies have shown that ethanol blends can reduce NOX, carbon monoxide, and carbon dioxide emissions by as much as 30%, but some studies have concluded that its use may increase ground level smog.

As far as price, if you are paying more for 10% ethanol blend than normal gasoline, either supply is very low in your area, or you're getting taken advantage of. The blended ethanol displaces an identical amount of more expensive gasoline increasing total supply. In addition, ethanol raises the fuel's octane rating, allowing distributors to sell lower grade gasoline at higher grade prices.

 

this is everything ive been reading...thank you. and as far as the price for the 10% blend its 2 cents cheaper then all the other gas stations.

 

jdm b16 swap..

 

how would that require more than 93 octane?
