Not 100% E85.

You can throw a gallon in the 15gal tank if you want

No not really.

If you put in just e-85 you will run lean and can blow your motor.

It does act like 105 octane fuel but you must spray more volume to make it act that way.

You gain no performance by throwing it in with no tune, and I would not do it.

3 galons of e85 in 91 will give you 93, but why not just tune for e85 if its next to you

e85 is not 105 octane, ive read up on it and its actualy around 95, even though some gas stations claim 105

Short answer is don't bother unless you are going to to tune for 100% usage. A little bit isn't going to do anything.

It is not 105 octane from the pump it never is its actually less but when you tune for it I.E. add more volume it will give you the performance gains similar to a 105 octane fuel.

Where did you hear this bogus fact? E85 is like running 105, I test me e85 and it's sometime as hits as e90

Its definitely not near a 95 because I run a mix of 1 E85:3 91Oct for my 93 map, no knock, no pinging, no nothing. If it was rated at 95 I would definitely notice performance issues.
