BP Gasoline and Ethanol

The most useful post in the whole thread. Thanks.:)

I agree.....

So do you guys think that the paragraph I pulled from the BP website in my original post is misleading in saying their Ultimate Grade does not contain Ethanol.

I need to fill up my regular car, going to go to a BP station and see if there is an Ethanol sticker on the pump.
 
I will have to check out a local BP station for alcohol on their premium gas. I don't normally do business with BP but it is worth a look.
 
After reading posts here several months ago about ethanol in our gas I did my own survey. I found that Marathon was the lowest in ethanol at about 7%. That is still too high IMO but it's the best I could find short of filling up at a marina.
 
While the car had been sitting for the 3 months, I rebuilt the carb, fuel filter and gas shut-off; so all of these items, as well as all fuel lines were empty and dry. When I put in the 1 gallon of new gas, I found the next day that my carb. had leaked over night, filling up the 'catch' can I had layed under it in the engine pan. The collected new gas, had a significant amount of water in it !

I spent the next several days taking stock of this new gasoline and found that it continued to develope water in it. Not being a petro-scientist, I can not assign guilt to the gasoline. But I certainly did take note, and will now constantly be on the look out for water in my California gasoline.

HOW TO TEST FUEL
FOR ETHANOL
To determine if ethanol is in the gas:
On a test tube or olive bottle six or seven inches long, make a permanent line about two inches from the bottom.
Fill with water to this line, then fill the tube to the top with gasoline.
Cover the tube, agitate it, and let it stand.
The ethanol and water will mix and separate out together. If the water level appears to have increased, the fuel contains ethanol. Ethanol percentages of less than 5% can sometimes give a reading below the line. Therefore, any deviation in the water line indicates the presence of ethanol and should serve as a basis for indicating the alcohol in the fuel.

The percentage increase in the water is the percentage of alcohol in the gas. There are reusable calibrated tubes for sale as well.

There was a post here where a Fordbarn member added water to his gas to de-alcoholize his gas.
