well, I could mix a batch with pump gas added,
and it will either be Better, The Same, or Worse than without the increased gas content.
(of course, 'pump gas' in a lot of places is actually E10, I recall I used to see M10 pumpgas)

Sure, I can try a batch of 2 E85 + 2 E10 + 1Castor... uh.. E45o20? [&:]
