E25 is probably the sweet spot for most vehicles on the road. It supplies the octane, uses poorer gasoline so more gallons per barrel of crude, burns the most effiently of the blends in a conventional gasoline engine. There are less but per gallon, but E25 burns with a cleaner explosion, more efficently, which makes up some for the lower btu.
So of course, we set up E10 and E85, neither of which is a great mix for efficiency.
D'oh.
E85 could be quite a bit more efficient if we had dedicated engines that used the very high octane and other strengths of it, as Brazil does. But, we cling to using a standard gasoline tuned engine, and have the computer adapt somewhat for stronger ethanol blends.
When testing, one would need to run several tank falls to get the system fully to the blend you think you have, and for the computer to adjust fully to the stated blend.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
