I messed an older lawnmower and 4 cycle weed eater with ethynol gas (10%). Only non-ethynol gas around here is premium gas. Idea behind ethynol was we would cut imported oil and help farmers. Only thing it did was decrease mileage and drive food prices up. 90% of corn before ethynol was used for animal feed and export. Kind of stupid to burn our food.
Now we have a 200 year supply of natural gas and with the tax is about $1.84/gallon. If they want to cut imports without driving up food cost, convert fleets such as utility vehicles, UPS, postal delivery trucks, city buses, garbage trucks. It is very clean burning and since it is a gas like air and not a liquid, does not damage parts. We could cut 40% of imported oil by converting fleet vehicles to natural gas. We have at my company a natural gas/diesel blended vehicle (F250 crew cab) that when blended with natural gas gets 35 mpg diesel.
We can also make synthetic diesel from our abundant supply of coal to keep coal miners happy. The less fuel we import, the more jobs at home.
Lots of things we can do. Ethynol is not cost effective, it takes more energy to make it than what it gives in return.
