It costs less to produce, they get to cut thier product with it and charge you the same price. So they save money on production and make more money on the sale. All the while you are buying more gas because you are getting less miliage. Ok so it’s maybe one or two miles a gallon but figure that into all the cars on American roads and it ads up into the hundreds of millions of dollars in only a matter of days.

I track my miliage and have been running ethenal free for four months and get 1.8 miles per gallon better miliage that I did running E10. Ethenal also destroyed my Ducati gas tank after it expanded all the way around by more than an inch. Not to mention the fact that it burns hotter so it breaks down catalytic converters causing more harmfull polution. On an individual scale not a big deal but when you take into account all of the cars on our roads ethenal bites.

I own a simple ethanol test kit and can only speak on my personal experience.

The boat boys are somewhat right. Yea you can run a 9.9 on just about anything but the 275 Merc is a different story. I purchased the tester and have used it for years for my sleds. Snowmobile motors of older design will not deal with even 10% in a very short time the will score and die. This might be related to runing at 9000 RPM unlike your POS mower.

I can’t tell you how many times I’ve found fuel at stations and the pumps don’t say 10% blend and test 10% positive, and the one’s marked 10% have tested as high as 15%. If the regulation is so loose then there may be times when the E15 pump may be E20.

Here’s my real concern.
I own 20 antique cars. None of them are safe for even 10%
Old rubber hoses melt. Rubber needle and seats swell. Corvair fuel pump diaphragm swell to 3 times there normal size.

There was a recall on some last gen camaro’s and firebirds for there nylon fuel line’s melting when exposed to E10.
My friend walked out to his garage one morning to smell raw gas and find it dripping on the floor under his camaro.

The risk here is serious fire caused by fuel leaks.

Its easy to change the parts on a old Grand Am 4 cyl to stand the plastic melting fuel but anybody want to try a V12 JAG ?

As far as the octane ratings and the ECM tuning – Octane ratings only give you a good idea of how resistant the fuel is to self ignition or detonation.
Propane conversions are out there on fleet trucks “Schwanns Ice Cream” and Propane octane rating is well over 120 and it’s actually hard to tune them for even at 12 to 1 it will never ping. The big plus to Propane is it triples engine life.
It will also never make as much power as the same engine running 10/1 on simple Pure Premium Gasoline.
Even thought the Octane is higher the actual burn is slower and the result is a loss of about 10% power.

The way the octane test’s are done the E gas gets a better number simply because its harder to “self lite” under compression pressure. That makes the octane number higher by the test but what you don’t know is that it actually slows down the burn and the expansion just like Propane and that reduces power.

I have a friend that bought a brand new Chevy truck just so they could burn E85 and after a few months they switched back to gas. There reason, reduced mileage, and there view was this – I’m burning fuel and air “combustion” — how can it actually be cleaner to burn more fuel for the same work. Almost 20% more fuel, and for that additional fuel I need more air so I’ve actually used more air for combustion. In the end its more hot air and CO2 out the tail pipe.

Everyone seems to miss this one.

How can American farmers be working for Al-Queda? Does that mean my Uncle Ted is funding terrorism by making middle-eastern oil less relevant in the world energy scene? You had very well better have your ducks in a row when you answer that one.

Brazil has saved 800 million tons of CO2 since the beginning of its ethanol program 30 years ago.

Where excatly did they save it? Did they make dry-ice with it mabe? Is CO2 used to make powdered water?
