I'm new to e85 and will be burning my first tank on a new build soon. I have the car pretty much ready to fire and so I went to go test my closes E85 station and I came up with a 70% reading. I'm guessing that is a winter blend in my area yet and I have lots of stations to choose from but I am wondering about what time or what month can you expect to see the readings more in the 85% range.
