ethanol has 30% less energy, so it gets 30$ less mileage. SOOOO 15% at 30% is 4.5% less mileage. ethanol sells for 125% the price of gasoline, net is ethanol is 130% the cost of gasoline.

Its kind of funny because with a 10%-15% ethanol mix your car consumes 15%-20% more gas. So you will be filling up your tank more frequently and driving shorter distances than you would with 100% gasoline (no ethanol). Now I don’t know whether or not burning MORE ethanol mix is better for the enviornment than burning just gasoline. The ethanol does reduce emissions but does not get rid of them, so is burning say 1/2 the emissions for say twice as long better than burning more emissions at 1/2 the time? it comes down to Quality vs quanitity

1983 and later model cars – corrosion is not an issue because these vehicles are designed to handle gasohol (10% ethanol and gas mix).

Your miles per gallon of mix is reduced but you travel much farther on the gallons of gasoline you’re burning with much fewer emissions.

Start out slow with like a quart of ethanol mixed with at least 3/4 tank of gas. Run this tank out if all is good add a gallon to tank number 2. Record your percentage and note how the car runs. I’ve found that my family’s 3 cars run much better on blends upto 50/50. I had clacking at 85% ethanol and run at the 50/50 blend since. The vehicles start better and run quieter and smell better.

Shouldn’t be more than 10%. 15% is pushing it. That much might start damaging the seals. I think metal parts are ok, but the plastic/rubber will start to dissolve. There is less energy in ethanol gallon to gallon compared to gasoline, so your fuel consumption will grow or your mpg will be lowered.
