10% ethanol 90% gasoline
- Thread starter GT-N
- Start date
Your post is a little mixed, but if you want to know if 10% ethanol will hurt the NSX, in a word, no. From what I have read ethanol burns cleaner than gas. And no, you really do not, or will not, have much choice. I have been a Shell gasoline user for as long as I can remember, and they are converting to 10% ethanol in my area now.

I think in most U.S. states, summertime gas has been part ethanol for years. Switches back to 100% war catalyst in the winter months.

Thanks, totally agree. :biggrin: "I know everything there is to know about maple syrup. I eat maple syrup on pancakes, on pizza, sometimes I even put a little in my hair when I've had a rough week. What do you think holds it up slick?" :biggrin:

On topic... gasohol has been used in certain midwest/urban areas for generations.

Decade maybe. But I have places where I can buy the real thing-and I mostly do. Gas has more energy the alcohol, better mileage and a few more horsepower. We have been sold a fraud on gasohol.
My area has been changing to 10% ethanol. I asked my tuner about it and he said "that's good". He is a strong proponent of running methanol injection in high performance forced induction cars (which mine is). The alcohol burns cleaner and cooler than gas. He did tell me that it takes twice the volume of alcohol to produce the same power as gasoline. I wonder if that means that fuel mileage will be slightly lower with the 10% ethanol blends.
No, the winter blends drop the ethanol content to around 7 percent instead of 10 percent the rest of the year.Ski_Banker said:
There are no problems running 10 percent ethanol in the NSX. And because it's only 10 percent, any difference in mileage is negligible.
And corn growers love it! :wink:

I think the percentages vary considerably by state. Good to hear that it doesn't have any impact on mileage or performance or wear, though.
Hehe maybe that's what the breakthrough technology in the next gen NSX will be - nuclear fusion powered engine! :biggrin:

It's not that clear that ethanol is a good thing, unless you grow corn or are part of Archer-Daniels-Midland.

Great article. I especially liked...
"Surprise, surprise, it isn't. The move this spring by more regions to use ethanol means that demand has spiked, driving up prices. On Monday, the New York harbor price was around $3 per gallon compared with about $2.28 for gasoline (before being mixed with ethanol). In other words, for now ethanol is helping to increase prices at the pump, not to push them down.
"
Our state has jsut switched to E10 since April 2006. Up until that date we never had E10 or E15 before. Anyway, in my two daily driver cars I notices a 1-2 MPG dropped in gas mileage. This has been consistent in both cars.

You're wasting your money.
I've been on the track with 10% ethanol... if it would've done harm, I'm sure it would've happened already.

in greece u can get 100 octane @ any gas station thats nice !! come on here peolpe do the same thinkNSXchnk said:

The gasoline that's labeled 100 octane in Greece has about the same octane as premium gasoline sold in North America as 93 octane; they just label it using a different scale. Here in North America, pumps are labeled using (RON+MON)/2, which is properly called the "anti-knock index". Other markets, including Japan and Europe, use RON, which is higher than MON or our (RON+MON)/2.DIMITRIS said:
You can read more about gasoline octane and what it means in Part 3 of the Gasoline FAQ.
Higher octane in a car that's not tuned with more aggressive ignition timing and compression ratio is a waste of money as you will not benefit from it at all. In fact, there is a school of thought that says you may lose power if you go extreme. Higher octane gas burns slower than low octane (hence more knock resistant). This slower burning air/fuel mix in an engine tuned for lower octane means a less powerful "explosion" in the combustion chamber as pressure builds up over a greater period of time (slow burn)
Gasohol is said to have detrimental effects on older cars as the ethanol has corrosive properties. I read that certain parts of engines from older cars are of a certain alloy that is more susceptible to corrosion. This takes some time to show ie. you will not see immediate damage using it for just a few months
Finally, I can feel a perceptible loss in engine response on gasohol compared to pure benzene...this I tried on the Lexus GS
