Bioethanol?

Featured Replies

Hi, All,

At our local Morrisons they're now selling Bioethanol. Does anyone know if two strokes will run ok on this :)

Cheers, Stoford.

Is Bioethanol actually ethanol or is it car fuel which contains some (5% to 20%) ethanol?

I wouldn't recommend either for a two stroke trials bike.

If it is 100% ethanol you would need to radically rejet your carby to suit it and drain the fuel system and replace it with petrol each time you stop riding (to prevent corrosion of the fuel system).

If it is car fuel containing some ethanol, it will still absorb water from the atmosphere into your (vented) bike fuel system but less than if pure ethanol. The wet ethanol would give problems with corrosion within the bike fuel system. Modern cars have sealed fuel systems so usually avoid this problem. The trials bike with a carburettor would also need to be rejetted to suit the different fuel, if you want to retain smooth running. Again modern cars usually have fuel injection which avoids problems with the minor change in fuel properties.

In most european countries the 95 octan fuel contains 5% alcohol (ethanol) so changing from 98 octan to 95 octan means that the bike will run slightly leaner.

The E85 fuel is 85% ethanlol and demands a radical rejetting. 15% petrol is needed for proper coldstarting at low temperatures (less then -10C).
