However, it seems clear to me that (especially in the cooler months) I can't run E-85 all the time. So back to pump gas for now, give this some further thought and study and perhaps in the spring I'll try again.

BTW, the triple point of pure ethanol is 150K (-272.15 C or -457.87 F). That is freakin' cold. Its flash point is 16.6 C or about 62 degrees F, which is why you can't have any ignition source around it even at room temperature.

Thanks for the advice, all. It did the trick.

E85 is good stuff. I'm running flex fuel on ecutek. I didn't the extra for flex fuel just in case of this exact scenario
