MTBE replaced tetra-ethyl lead. It retards gasoline ignition, aka raises octane levels.

MTBE runoff dissolved in water and contaminates the water table, is not biodegradable within any reasonable period of time, tastes bitter and is carcinogenic.

Ethanol at a level of 5.6% functions like MTBE, or tetra-ethyl lead. Ethanol costs 1/2 cent more per gallon than MTBE. This costs the average motorist an extra $5 per year.

Like MTBE, ethanol runoff contaminates water tables but is broken down by bacterial action within days or weeks, it's not carcinogenic, and is not bitter in the interim.

Ethanol also acts as a an oxygenate which lowers some types of emissions, at the expense of raising others.

All in all using ethanol as and octane additive is superior to MTBE, or lead.

People who consider themselves ethanol proponents are usually talking about much larger percentages than 5.6%. This excites them because it lines their pocket. Enough said.
