Largely for safety reasons, US law prohibits the manufacture of most ethanol conversion kits, unless they are EPA certified. The certification process is too expensive and time-consuming to be considered a reasonable option for most consumers. | Largely for safety reasons, US law prohibits the manufacture of most ethanol conversion kits, unless they are EPA certified.

| + | *Because it's so corrosive, much (if not all) of the fuel system has to be replaced. | ||
| + | *Ethanol runs at a richer air-fuel ratio, so you need to use more of it. | ||
