I have the stock fuel system would it harm it in any way I want to mix 4 gallons of e85 and 10 gallons of 91

I gotta ask. Why would you want to?

 

[Doch01]

To run it on a 93 octane tune so when I take the car to the track ..

Mobil stations here in SoCal state on the pump that the gas is mixed with E85. Don't know what to make of this.

 

[Doch01]

Ok thanks for the info.
Ima mix the e85 and 91 and see what happens

I BELIEVE you will be alright running e-85 but after awhile it will wear your fuel lines, rings etc. Shit that wasnt meant to handle e-85. I have read about people running e-85 with stock fuel systems and not having problems and vice versa.

Dont run it so I am not too sure.

On a thread here it shows a chevy tahoe that was ran on e85 for 100, 000 and no problems...and the fuel lines were in better condition then regular fuel

Also is it worth it to upgrade mi fuel system to e85 for N/A and have it tuned
