All of the info looks good; high octane, clean burning, etc. but how would us hotrodders convert our old iron to run on that stuff? And where would we get ethanol? How much does it cost?
Aha, yes, 113 Octane Ethanol means we can build up engines with 11.0 compression ratios without worrying much about knocking and pinging.
