I really do not like this 10% ethanol gas!
 

Our Cayenne S gets horrible mpg and has less power ('08 "S").

The Boxster also runs way below the real available power and mpg isn't that good either....

Ive been running Eth-free for years

ethanol gas
 

I was listening to a program on national public radio talking about some of the effects ethanol has on gas motors. Rust was the main problem area that seemed to stand out to me. I would not put the stuff in my lawn mower after listening to that program. NPR is usually pretty balanced about things.

When I was in NC there were a couple of places that sold ethanol 93, now that I am down in FL I haven't found one yet that is close to me.

This site is where I found the ones that I did find. Just be careful to verify that it really exists and that it is open :) And where it says it is...

If your cars are down on power and have bad MPG's by running 93 octane with 10% ethanol, than you have other issues. Power should not be effected, at all. And MPG's will only be slightly less.....<10% less.

0 ethanol for my box.

I've traditionally used either Shell or Sunoco in the Box, at 93 Octane, presumably with ethanol. Have never sought out ethanol-free. Looking at the site listed above (puregas.org), for Ohio (where I live) the only local ethanol-free stations listed are designated as "Unbranded" (vs Shell, Marathon, etc). They're like "Ravenna Oil Company" or at marinas. None of them offer anything above 90 or 91 octane.

Without knowing more about them, I probably shouldn't disparage the Ravenna Oil Company specifically, or marinas generally, but I'll risk it anyway...For those of you avoiding ethanol, are you having to make those kinds of compromises? You like ethanol-free 90 or 91 octane better than 93 with ethanol? Or can you find alcohol-free 93?

Guys with high compression engines and turbos LOVE ethanol.

Ever hear of E85? As in 85% ethanol? I think the octane rating is 108 or 118, and most importantly, it COOLS the charge air dramatically.

Youd have to add in another 17% of fuel to compensate. But it really helps make big power.

Over here, northern Europe, a 5 % mix of Ethanol in both 95 and 98 Octane has been standard for a long time. Have not noticed any issues with my Box at all, no power diff either on those few occasions where I use 99 Octane without ethanol. Also been running a Bi-fuel Volvo on E85 for three years now without issues. Guess there are some minor adaptations in the fuel system both regarding material and programming. The Volvo has a slight power increase on E85 compared to regular gas
However 10% Ethanol could be above the spot where there are no noticable problems for cars not prepared for it.

that Brazilian gas is not for performance vehicles. It's for econo boxes and family sedans.

Fear not Tesla is coming out with an SUV. If its got 416 HP at 89 mpg like the four door, I think many will trickling into the used car market soon enough. They just outsold Porsche in California. The educated wealthy love pricey SUV's just as much as the rest of the country. I just read that their new 32 AMP chargers can get you 150 miles of juice after only 30 minutes of charging.

I seek out nonethanol any time I can. I have checked milage and It is noticeable better. When using 10% ethanol in power equip (mowers, saws, weedeaters) the ethanol causes all types of problems That I do not have with nonethanol. The problem I am having is that the only nonethanol I have been able to find lately is 87 octane.

First off, North American Octane rating is different to European Octane (AKI vs RON). http://en.wikipedia.org/wiki/Octane_rating#Regional_variations

Secondly, European gas are cleaner (no DFI issues) than NA.

The only place I can find gas without ethanol in Ohio is at airports and marinas and I don't live near either one. Does anyone know of an alternative source?

I find it hard in the Wyoming/Colorado regions to even have 93 octane. Most pumps only have 91 w/eth at best, guessing because of the elevation. Any of you have/heard issues with 91 over 93 in high elevations?

I've driven my cars to both coasts more than once and have used both 91 and 93 without any issues.

I just leave this here:-

Compares E85 to 10% blend gas. I wonder how much better pure gas performs???

E85 GASOLINE with 10% ethanol
Fuel economy, mpg
City 7 9
Highway 15 21
150-mile trip 13 18
Overall 10 14
Acceleration

And this from from the U.S. energy information administration:-


How much ethanol is in gasoline and how does it affect fuel economy?

In 2012, about 134 billion gallons of gasoline (3.19 billion barrels) were consumed in the United States, which contained about 13 billion gallons of ethanol, accounting for 10% of the volume of gasoline consumed.

Most of the gasoline now sold has some ethanol in it, but the exact amount varies by region. In general, ethanol will not exceed 10% by volume. Gasoline with 10% ethanol content by volume is known as E10, and with 15% ethanol is known as E15. E85 is 85% ethanol and 15% gasoline.

The energy content of ethanol is about 33% less than "pure" gasoline, although this varies depending on the amount of denaturant that is added to the ethanol. Thus, vehicle mileage may decrease by up to 3.3% when using E10.

All gasoline vehicles can use E10, but currently you need a light-duty vehicle with a model year of 2001 or greater to use E15, and a "flex-fuel" vehicle to use gasoline with an ethanol content greater than E15. Most of the gasoline with more than 10% ethanol is sold in the Midwest.

non ethanol in ohio
 

I really went to school on this thread. I thought Ohio had to lable the pump with the percentage of ethanol if any. NOT Pure-gas.org click on your state at the bottom and a list will pop up. A small one in my case, oh well I guess my cars and mower will have to suck it up until we run out of corn.

Over here in CT 10% has been the law for many years now. Good luck trying to find fuel without the 10% requirement around here. Lower MPG and poor storage. But for something that is driven regularly it's not to big of a deal. Stored for 6 months and you will have issues. Draining doesn't work great since seals will dry and crack from the ethanol and leaving the fuel in absorbs moisture at a greater rate and spoils at an alarming rate so it's a lose lose. Only good option is keep running and cycle the tanks of fuel. Biggest issues are my motorcycles and 2 stroke outboard boat motors. I always have issues with storage and have learned a little about dealing with it over the years. Also bad fuel over 10% for example 20% will melt/clog a catalytic converter fast.

Yeah, I've had a ton of carb. problems with my YZF600 street bike.
