Your 2001 Saturn was designed with an eye towards potentially running on E85 (though it was never certified for it) and many GM corporate parts were rated for E85 as they were intended to be used in FFVs, so your Saturn is at least in part prepped for higher levels of ethanol in its fuel than most other vehicles.
Basically, I have no idea what I am talking about, and you just made me feel better that my car isn’t going to crap out if they put more corn in my tank. Aren’t there other biofuels we could be mass producing that won’t price food out of people’s reach?
