Are you guys seeing enough of a difference that this actually matters?
I mean, clearly there's a difference between E10 and E85, but as long as you're somewhere near E50, you're getting the benefits of the extra timing and cooling, right?

I run a lot smoother on E than on straight 93 and it certainly make more power.
But I can't say that I've really noticed much difference between E30 and E70 other than mileage.
My phone reads from the ECU and via Bluetooth calculates it for me.
