Ethanol 87 Octane. No Bueno. The hygroscopic nature of alcohol is bad because of the water it leaves in the tank, line, pump, filter, and carburetor. I strongly recommend the use of Non-ethanol gasoline, 89-90 Octane. The switch requires a vacuum tuneup to accommodate the timing needed to fully burn the fuel in the mixture going into the cylinder. For your benefit, there is a website that will show you where you can buy Non-ethanol gas nearest to you. That site is... |

89 octane corn-free gasoline is $3.469 a gallon this morning in Summerville South Carolina.

Balance that against maintenance and repair costs...

Stations here except Cenex Black Hills share the same pump and hose for 85,87,and 91 octane gas. So, unless the pump hose for premium is dedicated, you still get a shot of alcohol gas unless you pump into a vehicle first and then fill your gas cans.

I've found the Non-ethanol pumps to be stand-alone with one hose as is Kerosene.

What about Aviation fuel in Canada? Is that too alcohol now? |

Thank you for the ideas will stop by a small airport in the area, hopefully they will sell me some ethanol free gasoline. Marina hard to come when we are land locked with limited motorized lakes, closes one is about one hundred miles away.

Our local Cenex stations has a dedicated non alcohol premium hose and is 91 octane.
You can also go through some pain and suffering and make your own alcohol free gas. You get a clear bottle of your choosing and mix one gallon of gasahol with one cup of water. Shake it until thoroughly mixed and let it sit over night. The water will go to the bottom and take the alcohol down with it. Either siphon it down to the visible level or install a petcock just over the gas/water level and drain it out.
A fellow I bought a fiberglass motorcycle repro tank told me this. I had the problem of the alcohol dissolving the resin which came out with the fuel and coated the carburator shaft and valve stems with resin which then stuck things. A nightmare.
Aviation alcohol free fuel is a excellent fuel for storing in collector cars etc. It does burn with a white/grey color which is noticeable in the exhaust and spark plugs.
I think the aviation industry is headed for alcohol fuel. The aircraft has fuel tank drains to guess what, drain off any water. At high altitude it can freeze and cause engine failure. Alcohol is used as gas line antifreeze----------duh. The fuel systems need to be retrofitted to be compatible with alcohol.

Alcohol is used as gas line antifreeze----------duh. The fuel systems need to be retrofitted to be compatible with alcohol. I work in the petroleum industry and this is known by us as phase separation when the phases (ethanol and pure gas) separate, when it does occur usually the site gets an alarm that shuts off that line to the public but occasionally they get the bad product if things have been incorrectly programmed. I have asked for the top half of the tank when we remove the product but the major oil companies are not too eager about this and have advised me they take it all back to the refinery and get it reprocessed. In fact it is more of a hush hush affair and we close the site for "maintenance" since public hysteria is not good PR. I am trying to figure out a way to make this method in a larger batch then five gallons at a time... I am sure the neighbourhood would love me to make setup separating pure product from the ethanol (joking). I have been looking around so the local airport has 100LL but going to keep looking for Avgas 80 (the lower octane), local farm co-ops have the same issue with ethanol gasoline since the refineries are now producing this variant as per the Federal Clean Fuel Regulations. Thank you all once again for insight and ideas. |

In past winters I purchased bottles of Heat to pour into the gas tank on the pickup. The yellow bottle was ethanol. The red bottles were methanol. Mixed with the water in the tank to prevent it from freezing. When it got really cold say 40* below 0* we would pour in several bottles. Now I purchase premixed at the pump and no gasline freeze ups for several winters.
