15% Ethanol on our fuel?

[94svtturbo]

I only want the best for my car. I run premium fuel constantly but i have alwasy heard that Ethanol mixed with our fuel is bad for almost everything in a conventional gas engine. Just wondering what everyone's thoughts on this are? like pros vs. cons stuff or something? and anything you know about this stuff


I found a place yesterday to get premium fuel with no ethanol. Its about 80 cents more a gallon but im going to run that from now on.

80 cents more a gallon?! F that, that's insane. I never heard ethanol to be bad for our engines, I just heard that you can't make quite as much power with gasoline that has ethanol added.

As he said I have never heard of it being bad, or that it hurts the motor just not as much power available from it.

Now I know a guy that put some 92 octane in his camaro and then added 2 bottles of octane boost. three days later he needed a new motor......

I've heard that ethanol fuels can eat through your fuel lines if they're made of older materials, but I have no idea at what point they started using Ethanol friendly lines either. Ethanol laced gasoline also usually results in lower MPGs. I dislike Ethanol in our fuel.

I've never heard of 15% ethanol Only 10% max. In so cal most pumps say "up to 10% Ethanol" I've never heard of it being "bad" for the motor just makes less power and that it can eat some types of rubber and plastic

around here alot of high hp cars run e85, which is 85% ethanol, the rest is regular fuel. you can gain some hp by doing so, but u need different injectors (i think, dont quote me). but you lose mpg with e85 too..

 

[ttocs]

yea you need some big old injectors as it takes alot more fuel

I was reading that the EPA has just approved putting a 15% blend of ethanol fuel at gas stations around the end of this year. but the gas stations need to add another pump with a special sticker so its not accidentally used in the wrong vehicles. E15(gas with 15% ethanol) have only been approved for vehicles 2007 and newer. So this E15 should only be used in 2007 and newer vehicles that are safe for it. They are currrently trying to test on older engines and small engines to see if its safe for those.

My thoughts when reading this stuff was if E15 was only approved for 2007 and newer vehicles that are equipped to handle it. How can any amount of Ethanol be good in our "older" vehicles? How can E10 with 10% ethanol be good in our 1994-1998 cars that have no parts made to have Ethanol in them.

Im still learning about this stuff so i just wanted to see what other people have heard/read/thought about it

^Yes. your fuel system needs to be upgraded massively to run it. You need a lot more E85 than regular fun to get the same results i believe

Pretty sure Ethanol only gives 80% of the energy that straight gasoline does.. annd if 10% or 15% of your gas is made up of a 80% mixture.. Hmm, I need to figure the math on percent energy lost.

 

[94svtturbo]

Yeah i read the BTU output of both somewhere. and ethanol definately was lower in its BTU/ power output than Conventional gas. I just dont remember the percentages.

 

[Slykin]

I'm not sure about my math (brain isn't working right now) but if ethanol puts out 80% and you have 10% ethanol you're only losing 2% energy overall. It'd be 3% on 15% ethanol. Not much.

Ethynol is a form of alchohol guys...pretty sure made from corn. I think that yous have it backwards but the ethanol makes more power but with less fuel economy and burns cleaner therefore resulting in lower emissions from the tailpipe. The reason High HP cars are running ethynol I think is becasue it has a higher ignition temperature, therefore detonation factors are decreased allowing the user to run higher compression and
MO BOOST! SO ethynol = more power and better emissions - (fuel economy + limited use before switching to a capable fuel system)

Ethanol = higher octane = more timing = more power without detonation.


I get better gas mileage running pure gas though. Luckily the little rinky dink backwoods gas station near my house is ethanol free, and generally the same price as Shell or any where else.

True. but you are also talking E85. I was talking E15 in cars like ours that are designed or adapted to run on Ethanol. Our cars werent designed to run on 85% fuel and 15% Ethanol. They were designed to run on 100% fuel. so its sounds like its almost a way to water down our gas. And Ethanol will eat fuel lines and vacuum lines that arent prepped to resist it from what i've read. Im just trying to figure this out

Ethanol will destroy all of man kind. It eats entire fuel systems if it sits for too long... For example, dirt bikes and lawn mowers and such. It is especially bad for small engines. Trust me, my dad is making a killing off of people coming in and needing an entire fuel system because ethanol destroyed it...

 

[RockstarMentality]

Absolutely not. Ethanol = less power, less mpgs, and a complete waste of perfectly good corn.
It takes more energy to produce a gallon of ethanol, than the energy potential of that gallon of ethanol. Dont get me wrong, Alcohol is great, just not as a fuel source.

Try to Google some things before you post....ever heard of ALCHOHOL DRAGSTERS? But I do need to make a few more things clear. Our gas here in MD has 10% ethynol. Normal gas v.s. 10%ethyl gas= More power with normal gas (about 3% more HP) This is becasue the the alchohol lowers the BTU (fire, heat, POWER!! for you stoners out there) production of the engine. BUT, if you can compinsate with more air and more fuel you mill ultimately make more power than on gasoline...PERIOD. So really my equation was right.

 

[vermilion]

my exploder doesnt like any of it. it doesnt even like me.

 

[got5.0]

also, ethanol is very, very inefficient when it comes to mpg...
