E15 or E20 blend in Z06 to get 93 octane
Please no inexperienced comments. Can the fuel system accommodate this? It already must make adjustments for E10. This would be to get pump 91 up to 93 as cheaply as possible without buying race gas to blend it in 55 gallon drums or Torco which I've heard GM does not approve to be run. (It leaves deposits)

How much E85 would you blend to get to 93 Octane? Our best gas in AZ is 91 Octane. Thanks in advance!

You may want to post a similar question in the C7 Z06 forum for a quicker response.

Relying on trims for things like airflow modifications and ethanol just removes/reduces the computers ability to adapt to conditions for which it was designed.

It will use fuel trims to add the fuel and it will technically not be correct unless you use a flex fuel sensor and update the tune for it.
