If anyone is going to use auto fuel in their airplane, it is important to become educated in all aspects of its impact - not just whether alcohol/ethanol components affect the fuel tank, but other effects as well.

 

Solely in the interest of safety, it is useful for everyone to read all of the entries in the menu tree at:

 

 

Friends don't let friends use anything that ends in  "ol" when flying.

 

There are many engines STC'd to use auto fuel as long as there is no alcohol or ethanol in it.  Not a single listed STC'd engine is injected or has a CR above 8.5 (if that high). 

 

If you fly to densely populated areas in the continental US (FAA standards = more than 3 houses on the same street), you are likely to find ethanol laced auto gas - thanks to the EPA. 

 

Ethanol, among other things, retains water.  That fact alone can be dangerous to flight and to the fuel system components it comes in contact with (steel fittings exposed to rusting, etc.).

 

Good luck,

 

Lorn,

I asked Bill directly if his aversion to ethanol-blended fuel was related to
engine or tank integrity. He says the loss of power using ethanol-blends is
unacceptable, and that he is unaware of any issues regarding ethanol-blends
and Hysol.

Regards,

Mark

You had better read Bill's response more carefully. He says that he 
NEVER uses gasoline with ethanol.

I have seen a tank damaged. The damaged tank used auto fuel. I suspect 
that the cause of the damage was ethanol.
