I've never heard anything like this before...but if this were true, the only reason I can think of that might make it true would be that the E85 does not provide the lubercation cababilities that gasoline does. I watched a show on TV where they talked a lot about E85. They said the reason they add the 15% gasoline is for lubercation purposes, because Ethenol alone will not lubercate at all...So my only guess for this possibly being true is that the engines are dieing from lubercation related failures. But I don't really know.

 

Ethanol itself is about 10 times more corrosive than gasoline and the thing that happens is the valvetrain fails. It is even more harmful on engines that are carbureted because the air-fuel mixture gets on both sides of the intake and exhaust valves. It literally "eats away" the valves. So, to try and combat this, they use valves that are specially hardened and made of a different material. Still though, they haven't had much success with making it go over 75000 miles. I did talk to my friend that works there and he said that they ran ONLY E85 through the engine and not a drop of gasoline from initial break-in to the time that it failed. This would be a worst case scenario, but still, I don't feel comfortable running something through my engine that can cause it to wear out prematurely.

 

where is the profe there are techs out there that said lead did the same things when lead gas was fadded out to the gas we know and use. there are lead additives that will make it possible to burn a little hotter but will polute more in the air do to the lead. thats why it is easy to find out why lead gas is stoped its harmfull to the environment. with e85 i kind of speaking out hear where is the profe instead of my friend said this my friend said this. there is more needing to know outher than it suins valves and will not lubricate if so there wouldent be e85 period. pluse the state government that perchases mass quantitys of e85 for there fleet of vehicles police cars down to lawn mowers that use it in the state government job branch that uses outher means to fuil there fleet including biodiesel for there diesels they use half in one tank and half in anouther do to jelling of the biodesiel. where is the proof i am still trying to find evedince to back you but finding more agenst on what you are saying. if you are able to run e85 and dont want to use it on your believes no one here is twisting your arm. pluse there are others here that like performance and dont use e85 they dont juge some wish they could use both its a matter of opinion

 

besides using titanium will be ilogical to use as valves it will caust to much to do that if they use other matterial i like to find out what it would be interesting

 

i allready looked it up at work i called one of the techs that work at a chevy dealer ship he and others have said if e85 ruins there engins chevy and the whole gm line up will be bankruped. do to the car that gm made that are flex fuil that can use e85 and regular gas. if a person uses e85 all the time and times that one person five hundred times the gm face and the government will go bank ruped we as the people will riot do to the vehicles that are made that are flex fuil

 

You need to take a chill pill.

 

i just get a little ticked when some one will say my friend said this with no proff and also when some one will say cracker or beener

 

Dude its the internet...

 

It is a big publicity stunt in my opinion; the government using E85 for their vehicles. They get to say that they are using the "next gen fuel". Plus they probably get some or all of their fuel for free just by having vehicles that are basically a rolling advertisement for E85. I know that here in Michigan, the governor has a whole fleet of Suburbans that are flex fuel and they have been turned into exactly that. Most likely because they get good publicity and their is probably some amount of money involved with it. As for what I said about E85 ruining your engine, you don't have to listen to me if you don't want to. Go ahead and use a fuel that costs 40% less than gasoline and use 60% more of it than you would using gasoline. Sure it is "good for the environment" and "re-newable" and, I only have more to gain from people using E85 since I come from a farming family and a lot of the corn that we grow (not all, but quite a bit) goes to make E85, so, go ahead and help us farmers. I won't stop you. Also, who is saying cracker and beaner?

 

Any links to any articles about this on the web anywhere, especially w/ pics? I've honestly never heard of it before.

Here is my other thing- how does GM offer a 100k mile powertrain warranty if the engines fail in 75k miles on straight E85? I know a lot of people that have always run straight E85 trying to be "environmentally friendly", and haven't heard about their engines rotting apart. I'd just assume if that 75k engine failure was so common, then why aren't there crazy warranty claims for complete replacement engines?


I'm not trying to defend using it as a cheaper fuel (I think it about equals out with the lower gas mileage)- or being better for the environment. What I'm for is using it as a cheap race gas- around here 100 unleaded runs $6.50/gal; the stuff at the track is $8/gal (not sure what octane). E85 is like $2.25/gal and is just about as high of octane.
