Does anyone know if I can use E50 in place of mixing E85 with 93 at a 50/50 mix?

There is a place right near me that sells E50 at a pump and im thinking i can eliminate mixing,

Any info will be greatly appreciated, thanks.

 

Usually that's what we do. 50/50 mix of pump and e85.

It'll work fine once you add 15% more fuel to the injector constant in the tune if you haven't already.
