But I'm not concerned. However, I feel like I want to further substantiate my stance with evidence. We all know of the 100,000 mile E85 non-flex fuel SUV that was driven around about 10 years ago that experienced no problems at all. Beyond that, I do not know many real world examples.
I only know of two or three disadvantages, and they are all something that can be mitigated with regular maintenance or good part choices.
1: Stresses out the fuel pump, wears it down faster, solved with a third fuel pump or a beefed up LPFP.
2: Cold start problems, use less during winter.
3: Corrosion issues due to condensation, which I hear can be solved by not letting the car sit around chronically.
But, I keep hearing fanciful news reports about how E85 will blow up your engine and destroy your fuel lines and gaskets, which baffles me.
