I got one gas that was 87 octane and it was light tan in color. The other is greenish and is 90 octane. Each is from a different gas station. I was trying to test each fuel for ethanol so thats why there is a water layer on the bottom. Also noticed the greenish 90 octane gas has a "bubble" layer even after several minutes of settling after shaking the bottles. The 87 octane did not exhibit this.
So couple of questions:
1. Is there reason to be concerned about either? What color is E0 gas suppose to be?
2. Because of the "bubble" layer, does this indicate a presence of ethanol?
