How much ethanol is REALLY in my tank
The seasonal variability in ethanol content of E85 makes determining what the hell is really in the tank very difficult.
I too a closer look at this document, and I see that it only specifies MINIMUM ethanol content by month. The MAXIMUM content is ALWAYS 83% (so the 85 in E85 is BOGUS).
So I did the graph to figure out what is the most ethanol that could be in the tank, and what the least amount could be. I'm somewhere in between.
Interestingly, it appears that I am now above the ethanol content that gave me a CEL on tank #4. I'm still below the amount that gave me the first CEL.
