It seems EPA approved a partial waiver for the use of 15% Ethanol gasoline blends recently for road vehicles- don't know when this might show up in gas pumps near you.
I had lots of problems with E10 when it first showed up, so did a lot of other people. It wasn't mandated for Maine, but the oil companies didn't want to offer E0 and E10 together. After the initial row, they suddenly switched to E5-quietly, with no comment. I've had no problems with E5 in the PW, it's been used for over 20 years with no complaints about performance, mileage, or corrosion.
If E15 shows up, you can wash the ethanol content out with water. The 230 ran on 70 octane gas back in the day, so you wouldn't lose enough octane to matter. An interesting discussion of this at http://ecomodder.com/forum/showthrea...e-12697-17html . Pay particular attention to post #134 & 137 by Olympiadis, and post #163 by Nerys concerning ignition- especially the case of the Hybrid ignition system tweak- that really makes you wonder if E10-15 is aimed at getting Americans to buy new cars by making older ones too expensive to own.
