Gas Grade

Yes it should have 3 to 4% more energy, but where I live, it costs way more than 3 to 4% more. And at least where I live, it is out of the way, so I would have to drive more just to get it.
Aside from that and the extra pollution, there is no reason not to use it.

 

The "why" is that the ethanol is added partly to reduce emissions, nitrous oxide, I think.

In some parts of the country it is almost impossible to find gas without it......and when you do the price FAR outweighs the ~5% extra mileage.

P.S. It's been discussed on here before, probably a LOT of times.
Many questions can be answered with a search before posting.

 

As far as hard-to-find E0, the US Congress has mandated a certain amount of ethanol roughly E10 that must be used in the entire country so it is hard to find E0 due to renewable fuel regs.

In my opinion (and I think Congress realizes) E10 is not really cleaner burning in a modern car, which is why the mandates are based on adding a certain quantity of renewable fuel vs. some kind of emissions test. Prius is such as clean burning car, emissions are very low.

If I could find E0 at a top tier gaso station at equal cost, I'd use it in a hearbeat. But in reality I would have to travel 6 hours to find that (not sure it's even possible to find top tier E0). I might end up in Oregon before I found that.

 

If you look in the manual it states dont use Ethanol infused gas. I'm in Ca. kind of hard to do it here. But the 87 oct is the best to use, and high then that it is just wasting money

 

Gas station owners like to make money, which is sort of the whole point.
They sell E0 here, but usually at the grungier stations and usually for 10-15 cents more.

Since there are a limited number of people who go out of their way to find and burn E0?
There's no demand for more stations.

The closest gas station to my office claims to E0, but I only ran 2 tanks through my car to see if I could discern a real difference tank-to-tank.
Quite frankly?

I didn't see enough of a reason to justify visiting a grungier station, and paying more money for a very negligible mileage delta and no other benefit at all.
I like to believe that the folks in the Mom and Pop stores just buy the signs saying "Ethanol Free!!" and giggle at the gullibility of their patrons, but that's the cynic in me.

 

From Toyota's Manual
Use only gasoline containing a maximum

of 10% ethanol.

DO NOT use any flex-fuel or gasoline

that could contain more than 10% ethanol,

including from any pump labeled

E15, E30, E50, E85 (which are only

some examples of fuel containing more

than 10% ethanol).

 

Well the EPA doesn't quite agree with you because it requires an "oxygenate" additive in the high pollution areas and since MTBE was found to cause cancer, ethanol is about all that's left.
But yes, there are other factors too and there is not one, clear cut reason for it's being in there.

 

My manual says no such thing. Maybe you should look again.

Double post

 

You may wish to read page 572 (bolding is mine words are Toyota's)

On page 573 Toyota discourages over E10, no one here is advocating over E10.

 

Yeah! I saw that, You don't think goverment had some thing to do with that do you? Hummmm.

 

Just emissions and air quality! No mention of any ICE preformance or damage? Hummm.

 

No more so than 'the government' had to do with there being a Prius in the first place, no.

 

Also no mention of zombies, vampires or werewolves. Big bad government!

I prefer to protect against actual dangers, not fantasy.

 

Ok, ok I give no Zombies!

 

I never understood the whole ethanol thing.

let make a fuel that's not much cheaper, gets much worse fuel mileage, and as a result creates more pollution than a comparable non ethanol laced fuel.....

Lets make ethanol form corn(food) such that the price of corn goes up, and the resulting price in ethanol goes up....
Lets sue large equipment and machinery that burn fossil fuels (tractors ect) to create ethanol.

so in the end, we are producing more pollution than we eliminate... especial since many of the harvesters and such are not smog controlled equipment... The ethanol production ends up consuming more energy than its creating..

Here give me ten bucks and ask for change...and when I give you back nine, you can't complain...

Not to mention, that all of the problems associated problems with our lawn/landscape/ pressure washers/equipment which are not designed to run on ethanol and you end up with hard fuel lines, gummed up carbs, ect....

 

I can help with that.

Ethanol /ˈɛθənɒl/, also called ethyl alcohol /ˈɛθɪl/, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid with the structural formula CH3CH2OH, often abbreviated as C2H5OH or C2H6O. Ethanol is a psychoactive drug and is one of the oldest recreational drugs still used by humans. Ethanol can cause alcohol intoxication when consumed. Best known as the type of alcohol found in alcoholic beverages, it is also used in thermometers, as a solvent, and as a fuel. In common usage, it is often referred to simply as alcohol or spirits.

In the US?
We use alky in our fuel for a few reasons.
My beloved government mandates that fuel contain certain additives. Some states require still more additives.
Some of these additives can result in FLKs (funny looking kids.)

Ethanol is food.
Unless you're a Southern Baptist Preacher, represent the oil and gas industry, or you live in a desert country whose economy is petrol based?
Ethanol isn't really as bad as the FUD makes it out to be.
Fear, uncertainty and doubt - Wikipedia, the free encyclopedia So...
In the US we use a lot of corn to make ethanol.
Corn has a few other uses too....like sileage to make our cows fatter, HFCS to make our kids fatter, or sometimes we use it in adult beverages to make our population more mailable for the entertainment/news industry.
The United States is documented to be in the top 5 countries on the planetary lard-butt list, and obesity is probably one of the largest health problems we face (pun almost unintended.)

Putting it in a gas tank?
THAT'S probably one of the better uses for corn.

Very Very little corn is used as food food.

No offense, but if you have a vehicle, lawn-mower, weed whacker, pressure washer, etc that does not run properly?
It's probably not the E-10, It's probably a maintenance problem.
If your vehicle/toy/tool is too old to have been designed with E-10 in mind then it's probably polluting a LOT more than the large companies that have replaced the American Farmer.
I'm slowly converting to electric for all of these, but I still have nearly a dozen and all run just fine on E-10.

E-10 (or E-15) isn't a perfect solution but it has one advantage that makes it attractive to me personally besides the cost benefit.


They don't grow corn in the Middle East.

Pecae!

 

Corn on the cob, whole kernal corn, etc. is sweet corn. Dent corn is sileage, ethanol, corn meal, etc. Popcorn is popcorn.
Using dent corn as fuel may deprive cattle from food, but not very many human's eat dent corn.
