- 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
Hope this helps you. |
*asterisk* Ethanol is not particularly corrosive to automotive grade polymers.
