This is what Ethanol does to rubber...

You like videos, zombie!?
I've got one from our friends behind the iron curtain:

That is a very interesting video. Let's assume it is TRUE, and CORRECT. (Most likely is)
The difference between gasolines is something I have been posting for the reasons we SEE here. Better gas burns cleaner.
The one I do NOT understand is Bio Eth.  Eth. is distilled from almost anything, and is always the same regardless of the Source material. Perhaps the Bio eth is Bio diesel, and Eth?
The main focus is how clean it burns. That has not been debated on this thread. The focus is on the damaging or corrosive nature of Eth.
I FIRMLY believe Eth. is a MUCH better fuel source but parts of the world are not prepared to use it as a regular fuel base. I believe resin based fuel system components will replace the metal/rubber compounds we use today, and in that case Eth will reign supreme. Till then most of us are having to deal with force feeding, and costly repairs.
Thanks for posting the vid tho... It helps to "clear the air"

Impossible. Fuel for otto engine and diesel engines don't mix well. The first need a high octane rating, the second a high cetane rating.
Ethanol is pure C2H5OH, Biodiesel some C16-18 (much longer molecule).
Beeing a simple and well defined molecule, Ethanol isn't difficult to burn clean.
BTW: first synthesis of Ethanol by Abu Bakr Mohammed Ibn Zakaria al-Razi ~900 a.d.

So what are THEY calling "bio diesel"?

[zombie]

I meant "Bio Ethanol".
http://en.wikipedia.org/wiki/Ethanol_fuel
I found it anyway. I don't understand one thing. Wait yeah I do... Bio eth. is a way to label Eth that has more impurities. Same as Regular gas vs Premium. It's amazing what a tangled web we live in.
Then they tell us the earth is round on top of it all... When do the lies stop...
Wasn't it some of your pals that stated regular gas is every bit as "pure" as premium, and anything else is a waste of time/money?
I forgot to cut paste your vid...
Test burning of gasolines, ethanol and E40 (Тест бензинов, этанола и Е40)
This is what cheap (ie: regular) gas does inside your engine. The link just fell in my lap

Re: This is what Ethanol does to rubber...

This is the topic. Not how clean it burns. Nobody argued Ethanol doesn't burn clean.

Now THAT is an oversimplified and misleading demonstration of fuel cleanliness video.

Oversimplified perhaps... Even I understood the point.
Misleading in what sense? Even different grades of Paraffin have varying amounts of "leftovers" not removed during processing (and will show similar results). I am tempted to try it at home to show my customers that insist on using cheaper "pump" gas in their trailer boats.
Engines are easier to maintain if you use the best products you can obtain.

....i GOTTA stop reading this thread.........

I thought it died of natural causes. Seems to have Zombified...

I did consider, and figure this is the best place for this post. One of you were talking about cvk carbs, and I suggested checking the diaphragm. I said I have spares because they swell from Ethanol but they do gas out in a few days, and return to normal. Usually I get about a month before I feel a few mph missing, and slower throttle response. This goes for ALL cvk carbs that do NOT have an appended part # denoting Ethanol proof.
These are the same slide except the currently swollen one just came out. I'll take a pict of it again in a day or so to show you how it looks new once the Eth evaporates. Cool...

[zombie]

Oh yeah... The one beside it has been thru this several times. They both have.

The right one could be from my 2002 Doodo - because it's running with 35% ethanol, far beyond its specification.

Too, I have some power loss, mostly because I refused to adjust jet sizes and the engine is running lean. But fuel consumption stays unchanged!

Our current fuel prices: E85: 1.059€/litre, E10 1.729, E5 1.769, premium 1.809
Since April 2011 I've saved some bucks adding 1/3 E85 to 2/3 E10.

Ahhhh! You've been waiting my friend... Quickly now. "The games afoot!"

I boat and I boat a lot. That said I never had a problem, thanks to Yamaha being proactive and forcing me to purchase and install a 2nd water/fuel seperator that filtes things down to 10 microns.

Drop by any marina or just go onto any boating forum (thehulltruth.com) and look around at what this crap has done to the marine industry alone.
