No idea why HD insists on keeping with an old technolgy. (air cooled engines). The fact that 10% Ethanol in gasoline does not help because Ethanol makes the engines to run hotter.
Really?
Please inform us how ethanol makes engines run hotter.
I mean, it's a FACT, right?

Seriously, if you don't know something, please don't invent things and call them facts.

I honestly don't know what exactly the effect of ethanol is on temperature but it is a fact that ethanol has ill effects on small engines... just sayin..

Alcohol makes engines run cooler because it burns at a lower temp than gasoline.
Alcohol does not have a negative effect on engines except that it attracts water which can cause corrosion and in some cases can eat seals.

The reasons people say alcohol in gas is bad (beyond the corrosion issue) are not really the alcohol itself.
The only real bad effect of the alcohol is it reduces power output and increases fuel consumption.

What makes todays gas crappy is NOT the alcohol it is a combination of 2 things.
1) The additives that are put in to try to reduce the water issues and...
2) The reduction, by refiners, in detergent additives. The detergent/dispersant additives help keep fuel injectors, valves and cylinders cleaner, which makes engines more efficient and less prone to detonation.
It is suspected that they have lowered the amount of these additives because they are expensive and they problems are slow to become apparent.

Even though they are mandated by the feds to put in, at least, a minimum amount, some believe that is not being done because it is difficult and expensive to measure and nobody is really watching anyway.

Don't get me wrong I don't want alcohol in gas, it's just not the direct cause of the decrease in gas quality.

Indy cars run on a mixture of 98% ethanol and 2% gasoline, just sayin

Not quite true.

Introduing ethanol into gasoline may actually reduce engine temperature. This is because ethanol's stochiometric ratio (9:1) is significantly lower than gasoline (14.7:1), requiring more fuel to be injected into the cylinder for the same amount of air. More fuel means more latent heat of evaporation, which helps to cool the combustion chamber.

And even though ethanol has a lower BTU content than gasoline, the fact that more if it is consumed for the same amount of air means the specific output is actually increased. This is why those alcohol dragsters makes so much HP. The downside is your MPG will decrease accordingly.

BTW, top fuel dragsters run METHANOL, with an even lower air-fuel ratio (6.4:1). It is the same as in glow engines for RC airplanes. Any RCer will tell you you can tweak that carb needle till the engine is running slobberingly rich, and the engine will run so cool, sometimes you can put your fingers on the cyl head and not get burned.

The only negative effect of the typically 10% ethanol in gasoline is the effect on older engine with seals & gaskets that were not compatible with ethanol. All the cars and bikes sold since ethanol-in-gas became prevalent suffer no ill effect.

The Internet is full of urban myths.

Well now... that's the fault of them EYE-talians. Somebody forgot to tell them to get with the program.

They get too busy sculpting every little aluminum piece into an object of art, they forget to read the tech bulletin.

I don't invent it is out there in some news sources. From just a quick search I found this. Hope I'm really wrong 'cause it will be bad when they move to E15

According to the Washington Post:

http://www.washingtonpost.com/wp-dyn...903475_pf.html

From Green AutoBlog:

http://green.autoblog.com/2010/05/07...ld-damage-eng/

Quote:
The New York Times reports that the Alliance of Automobile Manufacturers, representing 11 automakers, has real data to prove (so they say) that E15 will damage numerous gasoline engines. Speaking on behalf of the alliance, General Motors biofuel implementation manager C. Coleman Jones said that the increased ethanol levels caused problems in at least half of the engines tested. E15 made engines run hot, compromised catalytic converters and even damaged cylinder walls. Jones added that E15 could leave motorists stranded on the roadside.

Internet hype comes about when people read things out of context and the media and blogsphere regurgitate statements blindly without fully understanding them.

Following my last post above... if the engine management system is not programmed to take into account the increased ethanol content, it will continue to meter fuel with the air-fuel ratio of E10. E15 has a combined air-fuel ratio that is slightly lower than E10, so the mixture will go slightly leaner. The potential result is the engine running slightly leaner and hotter.

Some EMS might have enough margins to overcome this variation, while others tuned for hyer-mileage might not. This is the automaker's concern.

Power equipment mfrs' concern are similar, but their engine have no sophisticated EMS or even FI - just simple Walbro-style carb with fixed jets for fix air-fuel ratios. No owner is ever going to know how to retweak the needles and jets for the new fuel blend. So they run hotter and die sooner.

Challenges there will be some. Impending doom it will be not.

Round about way of getting around the farm substidy that the govmint cannot keep giving to the US farmers, in light of global free trade. But that's just my politically skewed view on the issue.
