E85
 

Is it safe to switch from 91 to E85?

whats the pros and con?

edit: wrong

You need a tune before you can use E85.

Pro: It'll make your car faster.
Con: It'll make your car more thirsty.

To be clear, absolutely not without a tune. This car is not "flex fuel" aware and you could run dangerously lean. With a tune for E85, no problems. Books already explained the pros/cons of an E85 tune.

Thanks guys just wanted someone to give pros and cons of running E85 on non tuned or non flex fuel cars.. just in case someone wanted to search for it and found nothing.

Pro. You get more exercise by walking everywhere
Con. you blow your engine.

Nice Pros!
