Where is a good website for a listing of gas stations with 93 octane non-ethanol
gas?

Thanks Sam

If there is it doesn't have Hawaii listed.

You miight just go by which stations do sell it and look up their locator portion of their website.

Don't know if all the stations listed on this site carry ethanol-free gasoline, but worth a try..

Shell is the only station I know of that advertises Non-ethanol gas. But you most look on the pump because not all shell stations use non-ethanol gas. But it must be posted if they do.

Can't find any in S. Florida

That's a great help, thanks.

Here in North Florida, the Gate gas stations at marinas sell certified ethanol free gas. Most of the pumps are actually out on fuel docks. But my local Gate gas marina is right next to my marina, and their actual pumps are on dry land by the tanks (long hose to the dock). But they also have a short hose at the pump for classic and antique cars to fill up. Price per gallon is usually about 30 cents more than the local Gate gas stations one block either side of the marina. But soooo much better for your fuel system.

Other than Gate, there is a Sunoco gas station here in Jacksonville that sells several grades of race gas, all ethanol free. They have stuff like 100 octane, 105 octane, and 110 octane, etc... all are the same price... $9.00 per gallon.

Most of the Sunoco race fuels are LOADED with ethanol. Much more ethanol than regular pump gas.

We use Sunoco 260 GT+ in our race cars. Sunoco rates this fuel as 104 octane. That stuff is somewhere near 85% ethanol! I believe all of their race fuels contain ethanol.

I had a waiver (called an STC) on my airplane to run autogas but it was very strict about it containing NO alcohol (ethanol). The gas stations were very coy about advertising ethanol content so I had to test for ethanol. Very simple test for pennies.

Start with a test tube (or any kind of "gas resistant" clear tube) and draw a fine line about 1/4 way up from the bottom. Fill the tube up with water exactly to the line. Now add the test gas (over the water) almost to the top (gas and water don't mix well so you'll see the line of separation). Cap the top and shake vigorously. Now wait for the mixture to all settle out. When settled and the mixture separates again, if the "water" line has increased past the original amount you put in, that's alcohol.

You can use this to compare brands for the least amount of ethanol by keeping track of your results. Since alcohol bonds with water (and gasoline doesn't) the "apparent" volume of water increases with alcohol content after shaking. FWIW - I always found that Chevron and 76 had the least (if any) ethanol content. Alas, I think California is now void of ethanol free auto fuel.

Have you tried a website called Gasbuddy.com? There is some helpful info on the types of gas your looking for. They may or may not list non-ethanol stations in your city.

Great stuff....... Has anybody seen any ill effects in their engine due to Ethanol residue?

The "Stewarts" gas/convenience chain stores in northern NY are ethanol free. Why? They purchase their gas from Canada.

Why are you all so concerned about ethanol content?

samk

From Consumers reports:

Ethanol's lower fuel economy results from its lower energy content compared to gasoline. For example, E85 contains 75,670 British thermal units of energy per gallon instead of 115,400 for regular unleaded gasoline, according to the National Highway Traffic Safety Administration. So you have to burn more fuel to generate the same amount of energy. In addition, FFV engines are designed to run most efficiently on gasoline. Some engineers we interviewed say E85 fuel economy could approach that of gasoline if manufacturers optimized engines for that fuel, however.

Ubermensch

Yes, but there is only ~10% ethanol is most gas. So you're only talking about a total reduction in energy content of ~3.5% for a 90% gasoline mixture in comparison to 100% gasoline. At least for me that's not worthwhile chasing...
