Our government (USA) subsidizes the gasoline/oil industry. Also, we don't really get 'pure' gas. They mix all kinds of stuff in it, like benzene and toluene and ethanol and blah blah. That's why it's so cheap here.
When I was young, a friend of mine's dad worked for Arco. He told us over and over again to never use Arco gas in our cars when we get older, because there was so much horrible crap inside of it that he couldn't even List It All. Then, when my friend was 12, he died of cancer that was more than likely related to his job. I'm sure our gasoline has all kinds of horrible stuff in it, and thinning it out with that stuff probably makes it a lot cheaper haha.

Gasoline has always been a blend of hydrocarbons, a 'fraction' of petroleum. There is no 'gasoline molecule'. There are only performance standards for vapor pressure, octane number, dirt, etc. Those performance standards vary with location and time of year as well as which feed stocks they come from and international agreements.
Additives, like detergents and solvents, are also mixed in to improve performance and reliability.
Ethanol is an additive also but it causes problems since it has properties that don't make it mix or perform well in gasoline. It is hygroscopic, a polar solvent, has lower energy content per gallon, and a gasoline/ethanol mix eats the hell out of gasket materials called elastomers (many people call rubber).
Jet fuels, bunker oil, kerosene, gas, gasoline, diesel fuels, etc, are all just fractions of petroleum which is a varying mixture of hydrocarbons made up of star dust and whale shit. They will never run out of oil since it is just part of the 'carbon cycle' that transfers elements in and around the Earth. Organic matter, wood, fiber, leaves, bacteria, shit, that is a mix of hydrocarbons and water gets buried underground eventually. The waste then compressed and heated to form coal, gas, and oil. The oil and gas migrates around some and even comes bubbling up to the surface again. There are many hydrocarbon seeps all over the world both on land and under the sea.
Carbon, coal, and oil is everywhere. One just needs to look for it. Oil requires refineries to separate it into fractions to use. Oil exploration requires political will power which many places lack. NIMBY's are everywhere.
I like my big 400 cubic inch V8, and my 3.4 and 4.0L V6's. Power is good.

FrankenMech has said it well. One of former co-workers called it "methyl-ethyl bad shit". That kind of applies to anything manufactured from "crude" oil. The basic carbons are highly modified via fractionation and reaction of various methods. Separating crude into fractions of the alkyne chain. You may have heard these bantered about in ads and such: Methane,(C1) Ethane,(C2) Propane,(C3) Butane,(C4) Pentane,(C5) Hexane,(C6) Hectane (C7)and Octane.(C8) Lighter to heavier as the number gets bigger.
There is more, but those make up the common most elements that you buy at the pump and at the store.
Real basics: The above are carbon molecules, separated from crude. Hydrocarbon's are made by the addition of Hydrogen molecules to the above. They kind of like each other. Formed through various reactions with heat, pressure and a catalyst while injecting pure hydrogen.
The crazy compounds are for a wide variety of reasons and seasons. Yes, seasons. In hot temperatures, the lighter additives will tend to vaporize. In your engine? Good! In your fuel tank? Not so good, meaning that summer and winter and everything in between have different blends of compounds.
Refineries have recipe books for fuel blending. You would not believe how many variations there are. Additives are for performance, weather, corrosion and more.
My favorite engine? Cummins 5.9 HO turbo-diesel. Straight 6 with 325 hp, 610 lb.ft. of torque.

Ya, the politicians are hard party animals. Meet Mr. Chip Baltimore (R), state rep from Boone, Iowa. Mr. Baltimore was a staunch opponent of a certain plant being used as medicine, even by terminally ill humans. He got popped for drunk driving at 3AM, twice the legal limit. Mr. Baltimore is also the chief counsel for a local bank that counts a large number of corporate welfare farm clients, and has a been a staunch supporter of farm welfare and ethanol. Mr. Baltimore, sadly, has announced an end to his fledgling political career, and will not be seeking re-election, probably because he seems reluctant to say what strip joint he was coming home to his wife and family from...  Politicians are scum of the earth. |

On an adventure bike forum there was a thread a guy wrote where he took 5 gallons of gas with ethanol in it. He put enough water in the container to cover the top surface of he gas and let it sit for a couple of days. Then he siphoned off all the water from the top and had 4+ gallons of pure gas. Don't know if it would work or not.
With diesel, back in the day you could spill some on the floor and it would remain a puddle of fuel for weeks. Today's diesel will evaporate in a few hours. Today's diesel has less BTU's than diesel from back in the day.
On my bus I put a long hose connected to an electric fuel pump down in the sump and pump out a couple of gallons into a clear container looking for water in the 140 gallon tank. So far it is clean but I never park it without filling it to the brim. When I change the fuel filters I cut them apart with a filter cutter and check between the pleats for debris and water-so far they are clean. I have a friend who bought a bus that sat for ten years with 1/4 tank of fuel. He drove it home and filled it-250 gallons-just before he got to his home and in the morning there was fuel running down the driveway! The bugs had eaten through the steel tank. It was not savable so he cut the top of the tank off and there was a line about 1" wide all along the inside at the top of the fuel level. Another way to get in trouble is to over treat the fuel. "More's Law" is a good way to clog up your fuel filters. That is if a little fuel treatment is good, more is better but you mobilize all the shit at one time and clog up the filters. I use a product called Shaeffer's that will keep the fuel system and injection components clean enough to eat off of. I carry two each primary and secondary fuel filters on board my bus and a 12 VDC pump I can hook up to the secondary filter to purge the air out of the system if I run out of fuel or have a clogged filter.
Diesel fuel cost less to produce than gas but it cost more at the pump. Some politician figured out there are more BTU's in a gallon of diesel and now we pay more at he pump. Truckers just make everyone pay more to have freight delivered, but us diesel car owners have to pay out of our pockets. Anyone who doesn't see how the gas producing industry is actively trying to keep diesel cars out of the US is living in a fantasy world.
Why has no car maker made a hybrid car using an electric/diesel combination like a locomotive is beyond me, but the gas producers' lobby must be very powerful. That and the EPA have a strangle hold on innovation. The EPA is not really working in the interests of the public. Jus' sayin'!

hydrogen gas, easily produced, as safe as LP, no monopolized technology needed, no monopolized fuel source needed and burns clean without any complicated emissions equipment.

Not sure what that 'experimenter' was smokin... If you remove the ethanol from the gas it lowers the octane rating.
A diesel-electric hybrid would be cool.
Our fuel distribution and storage system is set up for liquid fuels. Hydrogen is a whole different animal.

Since diesel was mentioned I’ll share that I found out bio-diesel has a short shelf life. When turns bad mold starts growing in it and no longer resembles diesel. It smells like bad gas, turpentine like smell and won’t even burn. Ive got a customer with a 400 gallon tank full of the stuff.

actually we distribute LP fairly well in America, so hydrogen wouldn't be all that hard, especially when it could be produced locally in a lot of cases, might be something to look at regionally, but discounting anything at this point is a good way to make sure the oil boys stay fat with cash.

FrankenMech, I probably misquoted him. Saw the thread 2-3 years ago. Removing the ethanol might make the remaining gas lower than regular gas as far as the octane.

Better watch out. The Ethanol industry is pushing for E15. Unless you own a 2011 and newer car you can't use E15. Ethanol industry is saying you could use it in 2001 and newer but thats a lie. As long as you use E10 gas you should have no problems. Just don't buy gas from any place that sells strait Ethanol and use pumps that mix. You could get a hose full of strait Ethanol before getting gas.

We went to Colorado in the Mercedes, using ethanol dorked our mileage 20% easily.
