No kidding I got some Cold Finished 6061 from Fry Steel recently that cut alot more like copper than Aluminum...Certed by an American lab CoO was Korea

4) If I were a betting man, I'd say they put a bunch of large beakers in a sealed oven (separated from the heating element of course). Set 1 sample in each beaker, hang the other above it. Let it sit for a month, checking occasionally for issues. Weigh the samples pre- and post-test on a digital gram scale. Closed environment means humidity control.

5) E85 responds very differently since it is anhydrous ethanol + gasoline. It gets all of the water separated out before blending. Once it's blended, it's fairly stable... but you're right it can absorb water from the air. E100 (in Brazil and other places) is hydrous ethanol that has 1% water and 99% ethanol. That kind of fuel has it's own can of worms... but it is a simpler fuel to design around (if you happen to have acres of sugar cane lying around).

This is interesting I was not aware that there was a positive (for this application) effect on water absorption by blending the Ethanol and Gasoline.
I had heard alot of boat owners complaining of the E10 blends not storing well due to the large vents on boats and the tendency to absorb water. Was this a scape goat for another source of water contamination possibly?
And Thanks, :happy0180:
