Ma Engines and E10 or E85?

[aLLeKs]

Hey guys,
we have a law here in Germany that all gas station have to sell e10 (10%Ethanol) the normal fuel will be more expensive soon.
So I have the question if the MA engines are able to take the E10 fuel, because I heard that ethanol is very aggressive to aluminium.
And if they are able to run with e10, are they able to run e85 (85% ethanol)?

I know my carb is able to run it, because I use weber carbs. If they are to lean I turn them richer or change the jets and mixture tubes.

The question is just about the engine block and the cylinder head.

No, you WILL #### the engine up with ethanol, do not use it.

But why?
I found the following table about the resistence (first number the ethanol resistance and the second for gas)

Bezeichnung Ethanol Gasoline / ASTM C
Chloroprene/ Neoprene 1 x
Nitrile 1 2
Polyethlen PE / CPE / HDPE 1 2
Teflon 1 1
Viton 1 2
Stahl 1 1
Edelstahl 1 1
Aluminium 2 1
Thermoplastische Kunststoffe (PA) 1 2


1 = excellent
2 = good resistance
x = not recommend

I tell you what, use it and see what happens... fwn

E10 should be fine. E85 will require work. Consider that most 99%+ here will have no Ethanol experience so unless people have first hand I'd ignore those comments.

I doubt anything bad will come off it. The little that i know points towards this being och to maybe even higher percentages?
