My usual station sells E10, E15, E30, E50 and E85. The E85 button says 51-83% ethanol concentration.
I wasn't able to make it to my usual E85 station so I used a station I haven't used before. Their E85 seems to be more gasoline than E85 as my truck has obviously reverted back to the gasoline tune (reduced HP/TQ). So, I have been trying to research the ethanol content minimum percentage required to trigger the E85 tune in my truck. Internet wisdom pins it between 70 and 80 percent.
Today I visited a third station in my quest for E85 with high ethanol concentration (still unable to make it across town to my usual station). I took the below picture at this third station. The button clearly states 70% minimum whereas the tag next to the nozzle cradle indicates 51-83%. I know the blend it down for the winter but which tag is the real/required specification?
I am planning on contacting my state's department of Ag (weights & measures) but per their website I am required to file a complaint to get it looked into. I just want to know which tag is what the station/blender has to follow.
