E85 is more for lower emissions, not for saving $. i think overall, at best you break even. But i don't see why bother.
E85 does NOT lower emissions, because ethanol burns colder than gasoline does, the sensors tuned to read emissions from gasoline will not read emissions from ethanol fuels, so it seems like emissions are lower.
no it doesnt. ethanol burns colder than gasoline does, which is why there is less energy per gallon of ethanol than gasoline. and the temperature different is not a couple of degrees either, but rather substantially more than that, more like 100 degrees.
You're right.. I have no idea why it got backwards in my head.. But, I still agree with the original point that the temperature differential on an engine between running E-10 or straight gasoline is negligible. Running an ethanol blend isn't going to cause a vehicle to overheat.

Incorrect, the o2 will adjust to stoich whether gasoline, or ethanol (read about function of O2 sensor). However, unless it is flex fuel the injectors would have to be 35 to 50% larger. In other words, you could take a 90 Corvette, and oversize injectors 40% and it would run on E85 all day long and at proper stoich.

i am not talking about the o2 sensors in the car, i am talking about the sensors at the emissions station where they read the exhaust gases. THOSE sensors are tuned to read gasoline not ethanol, which is why the emissions seems lower when you put ethanol in the gasoline.

again you are talking about the O2 sensor in the engine control system. it is different than the exhaust gas sensors used at the emissions station when they read the exhaust gasses that come from the engine. remember that the exhaust gas analyzer has to read several gasses in the exhaust gas not just the level of oxygen.
