Just a general question. I recently rented a car (Chevy Malibu)...went to gas it up and oh! Yellow cap that says E85. My questions..
Will the car perform better with E85 fuel? (mpg, horsepower/torque)
Is it "healthier" for this car to use only E85?
Lastly, What are the benefits of using E85?

Hello ModelWarships ;
Thanks for the link. Very informative.

E85 is subsidized yet the annual cost for using it is considerably higher.

to add insult to injury, Illinois has removed the sales tax from E85.

NO, look up your car on the EPA.gov gas mileage site and see how bad the mileage is on gas vs E85. Should be sobering.

I guess we don't know if this rented Malibu used any E85. Too bad.

Answer:
Only if you are heating water.

Question:
Since E85 is about 35% short on energy per gallon, shouldn't the gasoline tax be reduced by 35%?
And I don't mean subsidizing it like they do in Illinois. They have removed the sales tax on E85.

Use what makes your car perform better.

mblackiston, great question - and you got some fine answers.

Some people who have one disappointing experience with E85 fuel can't seem to get past the problem and that the real issue just might lie with the automotive engineers who designed an inferior product for that fuel - not the fuel itself.

You really need to have your own experience and that FFV rental is or would have been an ideal first for you.

So, if you did or did not use E85, please post again and let us know how it went.

What did you find? What do you think?

Use E85 if you want. You won't notice a difference in performance.

Works fine for me. E35 gives me same MPGs and far, far more power (turbo car). Oil looks better as well, although I have not sent it for testing.

No matter how you look at it, or how the government spins it, ethanol sucks and the fuel mileage with it sucks.

"ethanol produces less usable power then gas."

That's not true. Almost any car made today will produce more horsepower using E85. The reason is ethanol requires much less air to provide complete furning of the fuel. So, at full throttle, more fuel will flow through the intake.

I've driven using E85 for over 100,000 miles. I can not detect any measurable difference in fuel economy. While you do have the ability to use more fuel with E85, it does not mean it will always produce lower fuel economy. Depends on the car and how you drive.

As far as being healthier for the car, ethanol is both a solvent to both oil and water based compounds. Yeah, it will keep your engine cleaner. Furthermore, the only combustion byproducts are carbon dioxide and water.

The main advantage to using E85 is the products used to make ethanol are 100% domestic in origin.

Ethanol usually produces more power than gas. I think he means BTUs, but this is discussed in the Topic: BTU's are 35% less for Ethanol but we are not heating water...

ethanol produces less usable power then gas. So it may be a bit cheaper at the pump, but in the long run, per mile, it will cost you more. In my truck running on E-85 it works out to right about 21 cent per mile. When I run on 93 octane non-ethanol (which is priced higher) it works out to 15 cent per mile. If it were me I would just put the regular blend in and cheap out on getting the tank back to where it was when you turn the rental in.

mblackiston asks "Will the car perform better with E85 fuel? (mpg, horsepower/torque)"
Unless you have a very long rental period, I doubt you will discover any significant difference either way.

"Is it "healthier" for this car to use only E85?"
I don't know why you would care about the health of a rental, but it's designed to run on both E85 and regular gas, so I doubt any fuel is "healthier".

"Lastly, What are the benefits of using E85?"
According to the US Dept. of Energy's Ethanol Myths and Facts website, "Ethanol is a clean, renewable fuel. It is helping to reduce our nation's dependence on oil and offers a variety of economic and environmental benefits." and

"Ethanol results in fewer greenhouse gas (GHG) emissions than gasoline and is fully biodegradable, unlike some fuel additives.

Today, on a life cycle basis, ethanol produced from corn results in about a 20 percent reduction in GHG emissions relative to gasoline. With improved efficiency and use of renewable energy, this reduction could be as much as 52 percent." and

"Biofuels have the potential to significantly reduce global GHG emissions associated with transportation"
