Heh, you guys think we have it bad, what with fear of cost, performance, and corrosion. Go look up what Ducati owners are dealing with the last 5+ years. Freaking fuel tanks deforming due to incompatibility. There are even a handful of stories of tanks that have leaked mid-ride and caught fire

MazdaManiac 01-20-2011 11:53 PM

Yeah - The bikes with semi-structural fiberglass and carbon fiber are literally falling apart because of the incompatibility with ethanol.
I would imagine that some of the exotic cars have similar problems.

DocBeech 01-21-2011 12:20 AM

Whats really sad also is that we as consumers are being given no choice in the matter. Our cars are 30K+ investments. Some like Erics cars are 200K investments. Yet we are given no choices on how to protect them. I bet this doesn't help the recession either. Before you could buy a car and own it for 30 years, now after 7 years most vehicles start to fail from these fuels. Just wonderful isn't it :(

MazdaManiac 01-21-2011 12:39 AM

Well, there are proactive methods of dealing with it.
It is just a matter of how inconvenienced you are willing to be.

DocBeech 01-21-2011 12:50 AM

Just as I said I researched it. I didn't find a whole lot in automotive community. But I went to the AOPA forums, and a couple other aircraft forums I am registered on. I did find a lot of people having problems with not only carbon fiber, but with fiberglass fuel cells. They are having to switch to alluminum in places that have E10 or higher. Also I found information on people with fiberglass boats where the ethanol softens or eats through the boats who use the hull for fuel storage. They are also starting to show that valves break down when introduced to ethanol. Intake valves for one. They are finding corrosion and sticky intake valves. Sound familiar? They were finding trace amounts of parts of the fuel system in the intakes. They analyzed it and found out the ethanol had softened up components of the fuel system which began to redeposit on intake valve and inside of injectors. They are finding that plastics are easily disolved by ethanol then redeposited other places in the engine system. So basically from our fuel pump, to our SSV valve.

(Phthalates, or phthalate esters, are esters of phthalic acid and are mainly used as plasticizers (substances added to plastics to increase their flexibility, transparency, durability, and longevity).)
(GCMS - Gas Chromatography Mass Spectrometry )

"Phthalates are only sparingly soluble in water, however many are readily dissolved by ethanol. Whereas gasoline free from ethanol never picks up phthalates, when ethanol was introduced the very small ethanol molecules diffused into the fiberglass, filler and gel coat materials where they dissolved unreacted phthalates. Having been dissolved by smaller molecules, and almost certainly accelerated by osmotic pressure, some portion diffused back to the surface and was dispersed in the gasoline. Based on our GCMS results to date there are some other, presently unidentified, large molecules that were also leached out by the ethanol and similarly transferred into the gasoline."

"Since they are in solution, the phthalates and the other heavy dissolved molecules are able to pass through the fuel line filters. When the gasoline with ethanol evaporates in the carburetor the heavy molecules do not evaporate but come out of solution and are carried along in the air-fuel mix as an aerosol. When the droplets impinge on throttle plates and on the walls of the induction system they can collect as reported."

"Some of the molecules that impinge on the hot valve stems and under the crowns decompose to leave carbon powder and ash. Others, such as the phthalates that in general have exceptional high temperature stability, remain intact or undergo only partial decomposition and then act as the binder that holds together the carbon particles and ash as the observed"

Some of those should look very familiar

They are also having problems with one way valve systems like our oil injectors have. Basically the ethanol is capable of breaking down the plastic lines mazda chose to use. You can avoid this by making your own teflon lines. The plastic that is broken down in line, is not filtered and can clog the injectors.

Can you explain how ethanol can affect the Oil lines and oil injectors?

Well, on a stock setup fuel gets in the oil, oil goes through the OMP lines and injectors.

DocBeech 01-21-2011 04:23 PM

If you look at the oil reports we are getting back, and heres a part where I think Blackstone is getting it wrong. They are finding trace amounts of fuel in the oil. Now Blackstone says its because of our cars being city drivers, which is actually incorrect. A lot of us heavy track use cars are seeing fuel dilution in the oil. You can read through them all here:

https://www.rx8club.com/series-i-tech-garage-22/used-oil-analysis-post-them-here-184241/

Our oil lines are made from a plastic that is actually not safe for use with ethanol fuel.

Chris 01-21-2011 04:31 PM

another great reason to have a safe, fuel/ethanol free, oil reservoir for the omp

Yep :)

I feel like ethanol adding is somewhat reminiscent of what happened when lead was taken out of the gas....

REDRX3RX8 01-21-2011 05:06 PM

Luckily our premixing should coat fuel system enough to stop corrosion.

Next time I buy a nice car for the wifey, I'm thinking about diesel.

No coils, wires, plugs, and they're more quiet now.

I drove a C3 Citroen that had gobs of get up and go at 1500-3000 rpm, and there's allkinds of Vw's and Audi diesels.

DocBeech 01-21-2011 05:24 PM

ethanol unfortunately easily breaks through fuel and oil. Mixes with it and stays in it. The only way to get it out is with water. Even a small layer of oil from premixing will still have ethanol in it. Thats one of the big problems boats are having. Two stroke boats wouldn't be affected if this was the case. But unfortunately its costing boat and aircraft owners tens of thousands of dollars. I know our cost seams measly compared to theres but its still unnecessary. They are having to change out components for aluminum fuel tanks, aluminum fuel lines, new fuel pumps(on aircraft that arent gravity feed like cessna 152s).

Lets throw tax money at it so that Iowa is happy so that my presidential bid has legs since that is where the primary is held...

you forget we like to starve people to death like in Africa.

That's why Al Gore has changed his mind about ethanol from corn.
He is no longer a proponent of this.

In place of this he wants to kill America via the Mercury light bulb.

Funny thing is we can not have a thermostat in our house with mercury because it is too dangerous and is outlawed. However after the first major earthquake...

All of our homes will be condemned due to the hazardous clean up.

Can you really clean that mercury out of your walls and floors?

REDRX3RX8 01-22-2011 12:24 AM

Texas has certain (non-attainment areas) in which a certain fuel mixture is mandated, and I think that means year round 10%ethanol everywhere in those counties (no exceptions).

Those counties are ( Bexar, Travis, new), several DFW area, Harris, etc.

America is going to go bankrupt at the rate it's coming up with dumb ideas.

Just watch what's happening to LA county's budget, $600,000,000. year (yes, Millions!) just for illegal immigrants welfare. Just $21.8 Billion for all of California last year.

So we borrow money we don't have from people that are our competitors (China) to act like big shots around the world, and that sugar (social programs) on the table does'nt help in the long run.

REDRX3RX8 01-22-2011 12:42 AM

Razz1'

So I'm looking up more EPA nonsense, and some enterprising soul built a patented "Bulb Eater"to dispose of all those mercury bulbs in all sizes into a 55gal drum.

I shite you not!

DocBeech 01-22-2011 03:05 AM

mm its gets worse huh lol

Well, after checking the Murphy USA site, I found that not all have ethanol in the gas. So i went to our newest Walmart and the pump said nothing about ethanol. I'm gonna swing by in a bit to see if they said anything like oxygenated or anything like that.

yea i know we dont have sugar cane here.

my point is that if we can't do it, why can't we just let it go?

but since our big brothers in the white house think we are #1 in everything, we just have to do it, no matter what cost. so they came up with a much inferior solution (corn) just for the hell of it. and they forgot that unlike sugar cane, corn is actually edible everyday, u can't do that with sugar cane.

and yeah, those "go green" people usually just look at the good numbers and ignore all the side effects.

too bad our great mayor/Governor is such an asshole.

Yeah, I guess the cosolvent to bind the ethanol also allows an emulsion with the premix.

I used to drain 55gal THD's of a real sticky (like cobwebs) straight gear oil, and use them to fill with methanol; always clear methanol with slight oil coating on drum (no mixing or emulsion.

I always had to be careful when pumping oil based gas and oil or methanol( even one gallon of methanol to a truck full of gas acts like water).

I think there's a petroleum product of some sort that would coat the fuel system without guming up the system.

So model airplanes have been using methanol and nitromethane fuel for years, and the 2cycle oil is castor bean oil (might be too gummy for cars).

If they put ethanol in gas in some 3rd world countries, some people might pour water in some ethanol gas, pour off the water and ethanol mix, repeat and distill a few times, and you got corn licker.

You can't ruin gas by watering it, just pour water off the bottom, and suck gas off the top.

In fact widespread distilling might be the only way to get this shite stopped. the guvment hates not being in control.

nycgps 01-22-2011 11:35 AM

well, guess its too late

http://wheels.blogs.nytimes.com/2011...-in-auto-fuel/

*sigh*

time for more fuck up engines/cars/boats/whatever.

I think i am moving out of the state because Im sick of government/lobbyist forcing everything down my throat.

REDRX3RX8 01-22-2011 12:32 PM

We'll have a (choice) of ethanol blend to buy; 10% or 15%!

Decisions. decisions!

"It's hard; I have to work Saturday's and Sundays!":lol:

They sell next door to me in Midland, and I don't think it has ethanol, so, yeah, not all Murphys have ethanol, but I'd really be surprised if 100%gas can be found at street pumps in SA.

There's no one to check for the mandated 10% ethanol decals, and I don't think anyone at Walmart will give a straight answer.

I buy Texaco next door, and I know its good because I've gotten 27.1mpg out of it before.

However, I'm about to buy a test kit if they mandate it at all stations here.
