Gasoline & ethanol can be blended in any percentage so can Diesel and Biodiesel (vegetable oil)
Ethanol (grain alcohol) & Biodiesel (vegetable oil) are farm crops the U.S. farms out produces the world
The U.S. Government pays farmer not to produce (dumb) the Government needs to stop this and farmer need to turn any excess crop to fuel
So go open up U.S. oil drilling in ANWR, offshore, wherever you find oil in the U.S.
Make up any oil shortfall in blending in ethanol and Biodiesel (because you grow what you need)
The U.S. can be oil independent if we want and not by Government mandated electric cars or SUV killing fuel economy laws
But bottom line when crunch time happens I want to see the U.S. be able to meet its needs 100% in house
Then tell the world to pound sand
