E15 gas

Where the fuck did ethanol even come from? Emissions? It feels like a convenient way to discard excess ethanol.

 

Gas has oxidizer additives. The previous chemical they used was leaking out and getting into water supplies

 

If I am not mistaken, it is basically corporate farm welfare.

Any environmental implications (which I generally fully support) are tossed out the window with all the damage that ethanol has done. Bad fuel that has to be disposed of, manufacture of stabilizers, manufacture of ethanol resistant components, more volume consumed thus more that had to be manufactured and delivered, etc. It is all waste that is not needed for pure gas.

Just looking at the waste on the nylon motorcycle fuel tanks and damage to marine fuels systems would generally label it as a failed concept.

Concise lil interesting read.

 

There are plenty like yours, and lots of fleet vehicles, taxi's prolly - that run mile after mile on it just fine.

You do you, glad you're having good luck with cheaper corn fuel for your rig.

 

Interesting

 

It looks like my post was a paraphrase of that, along with the full story?

I have nothing against jobs creation and see environmental targets such like solar and wind farms as worthwhile. Low content ethanol fuel is just a disaster and more harmful than good.

Certainly though, a vehicle specifically tuned for high content ethanol, esp FI, can make really good use of it. That just isn't a majority of the vehicle fleet and high content ethanol is not generally available.

 

It's not like I have a choice anyway. There's nowhere near Milwaukee the sells ethanol free.

I'm not saying that I wouldn't prefer to run ethanol free. I'm just saying that, in my experience, the issues caused by ethanol only really affect vehicles and motors that sit unused for long periods of time.

In other words, I don't think that ethanol would ever cause a problem in a newer vehicle that gets driven regularly.

 

Yessir. Basically, don't let fuel sit for longer than 3mo. If it is going to sit add a marine-grade stabilizer.

My closest E0 choices are quite far away. It doesn't make sense to drive there for fillups, esp when Costco is $1/gal less. My real hope is that we get our heads on straight and cancel this failed policy.

 

Ethanol has different vaporization characteristics under high heat and high pressure(direct injection). Been a while since I read up on it though.

I haven't bought ethanol blend for 13 years...

 

I think the epa mandated to help the air quality in larger cities in which states as our has. Thing is, now over the years our vehicles have gotten better fuel economy, and cleaner emissions, so the question is...do we still need ethanol in all our fuel grades?

 

Yeah I agree 100%

I think it's also sort of to blame for why trucks like ours have crap for tunes/mapping/driveability software these days - making a fuel map friendly to so many blends only means it'll run fine on all but not great on one blend.

 

I'm fine with E-10. Never tried E-15. Only ran one tank of pure gas since E-10 came out. I was on a road trip between GA and CO 2 years ago. I found pure gas in MS priced about the same as E-10 at home so I tried it. I got the worst fuel mileage and reduced performance on that tank of the entire 5000 mile trip. It is my suspicion that the more expensive pure gas isn't sold in great enough volume to be kept fresh. The gas I got was probably old and compromised. And with the price difference I'd guess that isn't unusual.

In theory I should get 3% better fuel mileage, but will have to pay 10-25% more for the fuel. Doesn't make sense to me to spend the money. And that ASSUMES it is actually 10% ethanol. It is advertised as "Up to 10%". Chances are good that a lot of what you actually buy could be less than 10% ethanol.

I don't care either way about the politics of it. If it works, it works. If they want to take all of the ethanol out tomorrow I'm OK with that too as long as the price stays the same. All of the vehicles made today are designed to work with E-10 and seem to be doing just fine. And for all the worries I've never had an issue with older equipment. I still have dad's 25 year old Snapper riding mower. It's had nothing but E10 run in it for at least 10 years. According to all the "experts" the engine should have blown by now by running ethanol fuel in it.

 

Those old Snappers are indestructible! My Grandpa had one of those!

 

The Corn lobby supporting state and federal legislators.

 

Right now, corn farming is more like a "farmer welfare program",especially for large corporate farmers, than something for the environment. Mono-culture corn farming actually generates more environmental damage than the upside of reduced emissions. ~40% percent of corn grown in the US is used for ethanol production, meaning 40% of the farmers in the corn belt would go bankrupt if there was no ethanol in fuel. Several corn belt states are also swing-states, so there is massive political interest in subsidizing corn and generating "artificial" industries/markets for consuming the surplus of corn that there is no actual market for (ethanol, bio-diesel, high fructose corn syrup, animal feed, etc).

 

I only run the boat gas/ mower gas. I pay more for it but that's my prerogative.

 

From my naive knothole, guaranteed that we could be farming something useful in its place. Given these whacky days, we could at least be drinking the good stuff.

 

I taken apart to many carbs and fuel systems to use any fuel containing ethanol when I can avoid it. My small utility motors, and my boat outboard get real gas 100% of the time. I don't put any E10 in my motor vehicles unless I don't have a choice. Seen too many problems with phase separation and sedimentation.

Ethanol smethanol.

Do ya'll buy Top Tier gas?
