[Diy_efi] Is E85 worth it?

[Phil Lamovie]

Garret, it seems like magic to me.

>>> E85 has about 70% of the energy content of gasoline. So, e85 needs to cost
>>> 70% of the price of gasoline to break even.


Well lets see... 85% petrol and 15% ethanol would have at very minimum 85%
of the energy content plus 26.8/42.7 (specific calorific value in MJ/kg) at 15%
or
.63 of 15% or 9.4% of gasoline.

85 + 9.4 = 94.4 % the energy content.

If the fuel cost 5% less then it is "worth it" on purely financial terms.
