- Ethanol does not have detrimental issues with plastics and rubber seals, etc. Methanol, however, is corrosive to these materials
- Modern vehicles from mid-90's and up are designed to work best using 10% ethanol-blended fuel. They are calibrated to get the best balance of power and economy using ethanol fuel
- In many areas, the only way you can get 93 octane fuel is to use ethanol. The "regular" version of the same brand of fuel is typically 91 octane, or 89 octane

Great info!
Edit: I would like to add to your list, and this applies to e10, e85, and e100 mixes that just because ethanol contains less energy per unit it simply means you have to burn more fuel per unit of air, not that the engine makes less power on ethanol blended fuel. There are benefits and consequences to this, mainly cooler intake air charge resulting in more power due to detonation resistance and less mpg because of the additional fuel used, which you covered.
