It takes about twice as much alcohol to make the same BTUs as a gallon of gas that's why your mileage goes in the toilet. Now figure in the cost per mile plus the added cost of buying green fuel and you'll really hate those who are feeding us this BS.

One of the local auto parts store managers told me that he had went to a seminar put on by parts manufactures. They were told that many of the old fuel system parts are sustsepatable to damage by alcohol one inparticular is the old fuel level sensors.

It would be interesting if the car manufacturers would post mileage
figures using both ethanol laced gas and real gas. That might get
someone's attention. Did hit a station in AL last week that had
posted "NO ETHANOL." Price was actually less than big brand across
the street. Filled her up with all I could.

Hello everyone. I want to confirm your fears about ethanol in fuel for older vehicles. Ethanol is a nasty chemical that attacks a lot of common elastomers (rubber) in fuel systems. E-85 will wear out any rubber hose, fitting or gasket between the fuel tank and the exhaust pipe if it is not properly updated with current rubber parts.



I know really stupid stuff like this because I am in the rubber business. The gaskets and hoses you will need to change out must be made with FKM (fluoroelastomer) commonly known in the industry as Viton made by dupont.



I would be more than happy to post links to the dupont website about ethanol in current fuels if anyone is interested.



I do want to add that states like florida add up to 10-15% ethanol in standard unleaded fuel. This will most likely NOT damage your existing hoses and gaskets.



I hope I was some help to everyone with questions or concerns about ethanol.

The parts that we were developing for E85 were all stainless steel. I'm not sure what other manufacturers used for hoses, etc., but for our part (ethanol concentration sensor) the customer required SS. No steel fuel tanks allowed. Of course, ethanol is "carbon neutral", but only because the CO2 that goes into the air is "new" carbon as opposed to the "old" carbon of fossil fuels. The contention is that growing the crop pulled CO2 from the air, balancing it out. But that assumes that there would be nothing growing on the land otherwise. Really?

What do the farmers use for fertilizer? fossil-fuel-derived nitrogen. What does the farmer burn in his equipment? Fossil fuel. What powers the distillery? Fossil fuel, of course. If they used ethanol there would be virtually none left to sell. So if just as much fossil fuel is used to make ethanol as the energy output, why use it at all? Government subsidies, of course. You and I are paying for it.

A reasonable rule of thumb is that fuel economy is reduced not quite half as much as there is ethanol. 10% ethanol in the fuel will reduce your mileage by about 6%. It does increase the octane somewhat, but most engines aren't equipped to take advantage of that. Around here I see E85 selling about 15% less than petroleum fuel, and it will likely result in about 30% less mileage. Sorry, I'll pass.

Guys, from the other side of the fence, you can debate this issue all day but I have [people every day calling about bad performance.  The most heard thng is sputtering going up a hill then performance really drops off.  What I have found in every case-- not just a % but in every one--- the carb filter is clogged.  A WIX 33052 filter should be in every glove box.  Last nigtht coming from the shop here a guy heading back to SC stalled coming off the highway-- clogged filter.  Don T. heading toward me from Arlington Tx is down @ 4 hours from home, clogged filter.  I'm telling you this ethanol is the problem.  Lostening up crap in the gas station tank-- in the coach tank-- I don;t know where but it is clogging our filters.  Fuel hoses I installed 2 years ago are cracked and sucking air.  Hoses are coming apart & I am in harms way-- it's coming right at me and I'm hunkered down.  I'm installing FI hose and appreciate any professional input-- no
wives tales.  We all do have a serious issue here-- with the ZDDP out of the oil, ethanol in our gas I feel we are being attacked from all sides!

Right now I have people doubting this, I tell them just carry extra filters and call if I can help-- and they are calling!  Take this threat seriously!

I don't doubt it a bit Jim,
All my new hoses need replacing and as I replace them, it will be
with steel and the newer FI hose using the high pressure hose clamps.
We'll be burning cow manure in 10 years if the greens have their way.

What are the conditions of your new hoses that tell you to replace them? I have some fairly new hoses and fid they seem almost soft -- like they are becoming spongy.

Gary,

That is all true for a modern closed loop control engine. It has been my experience recently with the coach, that ethanol behaves like a non-reactive filler.

In short, 10% ethanol will give just cause just about 10% increase in fuel consumption.

The few people that I know that have E-85 capable vehicles will not buy it because the cost per mile is higher. (They are all engineers with OE here in Michigan.)

Good point, Matt. I was going from an energy per gallon basis. A modern engine will "learn" the energy content of the fuel and adjust things accordingly, at least for up to maybe 15% ethanol (E15). For a carburetor with no compensation it would have the effect of going lean, but I'm not sure how much - that would take some calculation :-(. Anyway, would the things that happen be beneficial? Murphy's Law would say no. We're probably stuck with burning up to 10%, hopefully not more.

Hmm, I remember that not too many years ago working on systems for M15 to M85. What happened? Just another fad? Will E85 follow suit and just disappear? I wonder.

BURN COW MANURE?!

Not in California. We biologically digest it. Burning is out of the question.

Any idea how far a Prius will go on a load of cow manuer ;~)

G'day,

Here's a link to the Goodyear web page that lists the kinds of fuel hose
compatible with Ethanol.

http://www.goodyearep.com/ProductListing.aspx?folderid=1036

Before I picked up Double Trouble from Ken Frey in September of 2008 he:

1) dropped, inspected and cleaned the fuel tanks
2) replaced all the fuel lines with SAE 30R6
3) added an in line fuel filter just upstream of the fuel pump
4) cleaned / replaced the fuel filter in the carb

We drove Double Trouble from Philly - Bangor - Niagara Falls - Orlando -
Houston (3500+ miles) with NO fuel supply system problems.

When I was at the COOP last year I dropped the tanks again as I wanted to
see what they looked like. THEY WERE IMMACULATE! Not a spot of rust or
contamination. We replaced the socks on the pickups and put them back up.

This year we drove from Houston - Duluth - Houston (4000+ miles) with NO
fuel supply problems.

Cracks in the bends. The kind of hose I used would probably never get
squishy. It was the latest and greatest stuff NAPA carried about 8
years ago. Fortunately, I came off of the pickups with SS lines taped
to the top of the tanks so I probably don't have to drop the tanks.

Roger,

I work with scientist and chemists every day from Dupont labs in Stowe, Ohio. I assure you that chemicals in concentrate vs diluted states react differently to rubber parts. E-85 is 85% ethanol. This would be considered a "concentrated state of ethanol". Gas with 15% ethanol is "a diluted state of ethanol".

Hence the reason that VITON is recommended in fuel systems with "concentrated amounts of ethanol" while standard elastomers are recommended in "diluted forms of ethanol".



Sorry for the chemistry lesson today but I believe it needs to be addressed.



Jeff
