NC Iowa | my flex fuel 2015 buick lacrosse will throw a code and go into limp mode if i use e-85. something to do with the fuel pump. my dealer replaced the pump under warranty once, but said it was on me the next time, as it was a non warranty fuel issue. now that gas price is lower, it does not bother me as e85 isnt enough cheaper than e10 to mess with. i also had to refuel more often on e85, which i wouldn't have minded if i was saving money. | |
