Just curious, what is STP fuel dryer comprised of????

 

I could not agree with you more. I live by an airport. Every day I see the jets taking off with pitch black smoke coming of the jet engines rear. Is that black plumes not polution ? The very fact that the EPA wants more ethanol in gasoline, (Which cuts into the vehicles MPG) and yet on the other hand wants to get greater MPG out of 2011 cars shows how disjointed the Washington mainstream. If your an engineer, as you are, your left confusion of which mandate the EPA is acually the one they want. I am just as confused and angry as you. This whole enthanol BS is crazy, Corn belongs on the dinner table, not in a 5000 gallon storage gasoline tank ten feet below the filling station.

And this is indicative of the current adminstration misadventures of wrangling with each other. What gets done is either too late or not-adequate once put into process. No matter what, it's sad.

 

In the winter here in Reno we have 10% and have for years, Never had an issue using it, Maybe a little mpg lost, Thats about it.

 

Theu ought to take that corn squeezings and make whiskey out of it. That's all its good for!!

 

I was awake in Organic Chemistry long enough to learn a few facts: 1. Ethanol has only 85% of the energy of an equivalent amount of gasoline, so the less ethanol-the more energy. 2. Octane has less energy than an equivalent amount of gasoline, so don't use a higher octane than you NEED or you're actually LOWERING the energy of your fuel.

 

What do you mean "Octane has less energy than an equivalent amount of gasoline"? Octane is a rating.

But I think I get what you're trying to convey. I run regular gas unless a planned "fun drive" is coming up. Motor doesn't need it, so it don't get it

As a direct replacement for gas in a stock engine I wouldn't like E85, but what about guys with boost applications? Maybe they could benefit from the higher octane rating of the alcohol and run more boost and make more power. hmmm, just thoughts.

 

I am on E85 now and am tuned for it, its good stuff so far. I have about 6 hours of reading into it and there are PLENTY of LS1 guys that have been using it for 2+ years with no problems. The smell is great.

 

Al Gore is an idiot!! Global warming my azz. Corn, a joke.

 

 

What he summarized is this:

Conventional gasoline = 115,000 Btu/gallon
Pure Ethanol = 75,700 Btu/gallon

E10 is 10% by volume Ethanol so its energy content is (0.9 * (115,000 Btu/G) + 0.1*(75,700 Btu/G)) = 111,070 Btu/gallon.

E10 has 3.4% less energy per gallon than pure gasoline if you're wondering why your mileage went down.

 

We have had ethanol for years, now we can only get 91 octane gas without ethanol, 93 octane with 10% ethanol. I dont run it in my vette because it sits to much, but my other vehicles I have never had any problems with it

 

We are going to see more ethanol in gasoline and pure gasoline will be getting harder to find. I'll be looking for a good tuner/mechanic that understands what adjustments or mods needed to get my car ready, able and willing to burn the new fuels.

 

I call shenanigans

 

Beats me, but it works. Took over 30 gallons of un-contaminated fuel (add 15 gal with one container of fuel dryer, drive until there's room for another 15 gal and more fuel dryer) and about 500 miles to clear the water out of the system. Vehicle is a 93 GMC V-6 with ancient technology TBI.

 

You are missing the point, it is not the small amounts of water from condensation that is the problem--it's the gallons and gallons of water which get into the underground fuel storage of an IMPROPERLY maintained filling station which CANNOT be filtered out. And, I will NEVER go back to the station that sold me the bad gas.

 

[QUOTE=manley845;1575626343]What do you mean "Octane has less energy than an equivalent amount of gasoline"? Octane is a rating.

Octane is a hydrocarbon with the chemical formula CH3(CH2)6CH3. It is a part of gasoline. The term "high octane" is an old advertising gimic. The "Octane Ratings" you see on the pump are fairly arbitrary, but standardized in each country which is why Euro "Octane Ratings" are different from US spec for the same fuel.

 

[QUOTE=jcgunn;1575633442]See, now this is the kind of response I like. Educational.

I will say that I do believe that "octane" is both a chemical and a rating, and it is the context of the usage that makes the difference. But, I still have to do more research in this. Gotta love learning

 

Just filled up today with 100 octane unleaded no ethanol Sunoco. Only one station around here that sells it and it's $6.99 a gallon, but I'll be damned if I'm putting this garbage fuel in my car!

 

You're actually wrong, but rather than getting into it, I would hope you just go look it up yourself and stop spreading this information which clearly lacks proper research and math. For me to get into why you're wrong is beating a dead horse, and it gets old correcting people and their misinformation and conspiracy theories.

LOL... Seriously, you went there?

You really think gasoline in those tanks sit longer than a couple days?! No.... Those stations are filled up very regularly. I can imagine that a gas station that is out in BFE may only need a fill up once a month, but even then we're not talking large quantities of water. Maybe a gallon every 500-600 gallons of gas. Quantity of gasoline doesn't change the ratio of water accumulation.

Oh, and since you obviously don't know that oil and water separate naturally, you obviously didn't know that water can be filtered from gasoline.

Seriously, a lot of you anti-ethanol people lack basic math and science knowledge. The only bad thing about ethanol that can be said with absolute conviction is that it is in no way economical to produce. However, all the hype about it being bad for cars due to water is absolute crap. It's quite annoying to hear you people spreading this misinformation. You people should be ashamed of yourselves for saying things without proper research.

 

I live in the middle of a corn field so I say its good stuff. The main problem of to much ethanol in some early cars are the rubber seals dry quickly causing leaks in the fuel system. It takes 100 gallons of clean water to make 1 gallon of ethanol. Al Gore apposed ethanol. The largest producer is A.D.M. Based in Decatur Il. ADM Wanted a 2% increase to 12% and the EPA went with 15%. By law it has to be marked with a warning 15% Ethanol added sticker and a seperate pump. Without starting a politcal debate I happen to know the main push of ethanol was from the Bush whitehouse. Its a good thing but its not when many corperations are buying water rights. Drinking water is already over $4.00 per gallon if purchesed in small bottles in a convience store.
