OK, I do not want to start a heated debate here. I would just like to post this for informational resaons, and you may make your own judgements....
More and more everyday there is ethanol being introduced into the gasoline we purchase. E-10 (10% ethanol usable by ANY car) E-85, and more. In most cases now, you can't even purchase regular non ethanolated fuel any more.
Why is this bad?? Ethanol is a "clean" "renewable" energy, and it "lessens our need on forign oil"...... or so they tell us!
A friend of mine, also on another forum, posted this.....
Ethenol is a farse at best. I've done the math on all my cars and my father in law's cars. He drive from Appleton to Green Bay every day and I use to. Using the E10 (not E85,) crap we get at least a 12% drop in Fuel economy. So in reality it takes MORE pure gas to go fewer miles. The ONLY people Ethenol is helping is the farmers and the people producing it.
Such a scam it should be outlawed.
If you replace 10% of the gas with Ethenol and you reduce your MPG by more than 10% you in reality are using MORE pure gas per mile.
I consistantly got ~28mpg pure gas 93 Octane vs ~25mpg on E10 92 octane driving about 120 miles a week over 2 or so months. This is mostly hwy driving, probably about 80% hwy, 20% city.
10 gallon tank (easy math.)
9 gas, 1 ethenol at 25 mpg means I got 225 miles on pure gas per tank.
10 gas, 0 ethenol at 28 mpg means I got 280 miles on pure gas per tank.
To go 280 miles on E10 you have to put in 11.2 gallons of E10 (280 miles / 25mpg = 11.2 gallons)
Only 90% of that 11.2 gallons is pure gas, 11.2/.90 = 10.08 Gallons of Pure gas to go 280 miles on E10!
That's .08 gallons of pure gas more to go the same distance.
Therefore, your actually burning MORE pure gas to go the same distance with E10 because of the negitive effects of the ethenol.
Ethenol is actually HURTING our dependence on oil, not helping it.

This is just a little rant that I wanted to bring to light of you all.
In MY OWN observations, I have observed the same poor milage, but I have also noted the following,
If you have a carburated engine, the carburator is not calibrated for ethanol. I never thought of this when I purchased a brand new lawnmower. I put E-10 in my new mower. It performed moderate at best, far less than I had expected - it ran semi rough, and definitely lacked power. I noticed the same in the powerboat and the outboard on the sailboat - lack of power, stammering..... Since then I have found a gas station that still sells pure gas. Now I run pure gas in everything, boat, mowers, ect. Now my mower runs phenominal - plenty of power, runs right. Same goes for all of the boats too.
SOOOO, if ethanol increases our dependancy on forign oil, AND provides a lack of performance, why do we have it?
I encourage you to look closely at the gas you purchase in the future, with those thoughts in mind.
OK, I'm done. I'll get off the soap box now....
