when does e85 typically switch to summer blends?

[builttodrive]

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.

Depends where you live an how long your winters last. Also if not many people are buying E85 it means it may take awhile before thenget a new fresh batch thats true E85

Around me its usually mid may before summer blend appears at the pump

I'm in the same situation, ready to switch over to e85 but can only find 65-70% around here. I may end up buying a drum of e98 and mixing down to 85 for tuning purposes only

I just tested the local meijer pump as I want to switch after this weekend. According to my test tube it's at 82-83% which is pretty good. This is in michigan also but in a busy area so it may sell more often.
