I will quot my self here.
"Weird that you have had so many problems my old Subaru with 240k ran better on E50 then E0 or even E10 and i did not need to replace my fuel pump after using it. Also I have not seen the same results as you when it comes to mileage I got 27 Hwy with the Subaru under normal driving conditions on E10 that's the original EPA rating."
So like I said before no eco driving or hypermiling was used and I saw no change in fuel economy with E10.
"I notice the "new" epa ratings the give for cars just happen to perfectly match up with the "e10" results people are seeing. HENCE why my cars original rating is 53/58 but its "new" rating is 46/51 or something like that.
Intentional? or maybe they are just using E10 in their cars and forgot to mention that in their results (bad science)"
As for your comment on the "new" epa ratings I am quoting fueleconomy.gov here.
"In 2006, the Environmental Protection Agency (EPA) published new test methods for calculating fuel economy estimates that are posted on window stickers of new cars and trucks and on the website, fueleconomy.gov. These new methods, which took effect with model year 2008 vehicles, brought the miles per gallon (mpg) estimates closer to consumers' actual fuel economy by including factors such as high speeds, quicker accelerations, air conditioning use, and driving in cold temperatures."
So unless the EPA is lying or just so happened to forget to say their figures are based on E10 the new rating are based on driving conditions and not the fuel used.
"You had problems with pinging? I don't think the ethanol is the problem. One of the reasons race car drivers use ethanol is its anti knock properties plus its a safer fuel.
I agree that the ethanol is not likely of any relation to the pinging. it however is NOT safer in fact its quite dangerous. maybe your thinking methanol?? its extremely corrosive and not safe for humans."
When you say this I have to ask do you know what ethanol really is? And I was not thinking methanol I would never get the two confused I make ethanol so I know the difference plus I WOULD NEVER USE METHANOL.
So what is ethanol it is ethyl alcohol also known as grain alcohol or drinking alcohol its the same alcohol that's in every alcoholic beverage sold.
When you say ethanol is quite dangerous I have a test for you that might make you think otherwise. Take two pans and put ethanol in one and gasoline in the other now light both on fire then use water to try and put it out. Now tell me which is safer. The other thing you will see in this test is which one burns cleaner, gasoline will have a dirty black smoke and ethanol will not.
ONE of the reasons touted for using Ethanol is that we are replacing 10% of our fuel with it so 10% less foreign oil.
This is true and that's part of why I like it. Fuel made in America by Americans. The other BIG reason for using E10 is its an oxygenated fuel and can replace the need for pollution causing additives.
"I know nothing I say nor anyone else will probably change things and you will do what you want its your choice but I for one will not use E0 even though I can buy it.
This tells me you were not looking for a discussion at all that you are quite closed minded. I hope I am wrong but that is what such a statement sends as its message."
I am sorry if you feel like I am closed minded or being closed minded that was not my intention.
"Granted if you are seeing less than a 10% drop in FE when using E10 OK from your perspective it might make sense (only if your ignore the ecological damage ethanol production causes but thats another issue)"
Like rmay635703 was saying the ecological damage from ethanol is do to poor industry practices not the fuel itself.
rmay635703 you said
"I also could never understand why e85 cars don't use a variable valve timing system"
Its really simple the auto companies don't care about producing efficient ethanol vehicles. There are really only two reasons they even make ethanol vehicles aka flex fuel, first its "green if you can fill up your suv with ethanol and secondly it improves their cafe numbers.
I understand that Billions were spent on fossil fuels before they became perfected and commonplace. I am also not against investment. I think cellulose ethanol is a good idea. I see several problems with it first the poorly managed investment. I see it kind of like hydrogen cars many companies have said we can do it just give us funding and we will do it yet lots of time passes and no hydrogen cars and this has been happening for a long time. The other problem I see is the potential for a new monopoly of our fuel supply.
What I said was not specific to coal powered electric plants but they are the worst. Even if they run about double the efficiency of a typical car is my understanding wrong that the efficiency of the electricity produced is much less then that by the time it gets to the point of use do to other inefficiencies/losses?
Also l was thinking about the whole environmental impact of coal including mining not just what the power plants do. I have heard of the micro algae pond idea and would like to see them do that.
Old Mechanic Do you know why Indy cars run E85 now and not straight alcohol? E85 is the industry standard, plus blenders get credits for mixing gas into ethanol.
