How long does gasoline last?

Don't worry about it if it's less than a year old. If it is more than a year old, there is a preserve you can buy at any auto parts store. You just toss it in the tank.

It depends on how long somebodies fart last where I'm at.

They use methanol.  Probably about 100 gallons or so per car.

Most would settle to the bottom of the tank and join all the rust that's already there. Carbon and Potassium Nitrate aren't soluble enough in gasoline (and neither is the graphite form of carbon used to polish the granules in commercial gunpower).\n\nHowever, the sulfur would partially dissolve and eventually ruin the car's catalytic converter. It might even lead to a bit of a smelly exhaust for a while.\n\nNow, if you didn't mean gunpowder, but mean nitrocellulose (which is a more common propellant in modern guns), then you could give him a nice octane boost. However, it takes several days to a week for nitrocellulose to dissolve in gasoline (depending on temperature and 'shaking'). So, don't expect much very soon.\n\nI think the thing you are missing here is that gasoline isn't burned in the tank. Only a small, filtered amount is burned in the engine at one time. That's why you get miles per gallon and not gallons per mile.

I know that Gasoline and the Carbon chained fuels separate into water and thicker part after so much time of storage if exposed to air.  If you keep an inert gas in the container you will be okay.  Doesn't go "bad" per se, but just won't burn after like 5 years of free O2.

I don't understand what you are trying to test or why you are doing the test. But  gasoline is a mixture of hydrocarbons ranging from five to twelve carbon atoms . Most of those hydrocarbons do not resemble benzene in structure. Gasoline has benzene as a minor component. \n\nA better substitute would likely be toluene or xylene since these are both very similar to benzene in structure and only differ by one functional group on the ring of carbon atoms.

Naptha (common usage), gasoline, and diesel fuel are both hydrocarbon chains. Naptha has relatively short chains, probably 6 to 7 carbons long. Gasoline is a little longer, in the 8 carbon region. Diesel fuel, yet again longer. I don't know the average carbon length for Diesel, but I'd guess around 10. The longer the chain, the higher the boiling temp, the higher the flash point, the harder it is to ignite, and the higher the viscosity.\n\nNaptha, as a term used in the US (common usage) typically means the same thing as what was most commonly used as lighter fluid in hand held lighters. In some Euporean countries, it's means an easily flammable, volitile petroleum product, of which, gasoline is one.

You get napalm.\n\nIf you google "gasoline and styrofoam", the first thing that pops up is a short explanation from totse.com which has a TON of other articles about things like this.

"If you keep it clean, cool and dry, diesel fuel can be stored 6 months to 1 year without significant quality degradation. Storage for longer periods can be accomplished through use of periodic filtrations and addition of fuel stabilizers and biocides."

Oxygen is constantly being replenished by plantlife, which uses the carbon dioxide created by the oxygen users.....if you want to walk to school, however, this will allow for more gasoline for my car.

Before the mid-1800's and the invention of the internal combustion engine, gasoline was sold as lice treatment and their eggs. The brand was "Petrol". No one knows when/who.

Question -   HOW MANY GAL.OF CRUDE OIL IN A BARREL? HOW MANY GAL OF GAS\nDOES THAT EQUAL?\n-----------------\nThere are 42 gallons / barrel of crude oil. The conversion to gasoline\ndepends upon several factors -- refining efficiency, product mix desired by\nthe refiner, quality of the crude to name a few. The following sites provide\nadditional info.\n\n http://www.petroleum.org/petrokids/petroperbbl.htm\nhttp://www.newton.dep.anl.gov/askasci/gen99/gen99675.htm\n\nVince Calder\n=====================================================\nA barrel contains 42 gallons.  After refining, it makes about 19.5 gallons\nof gasoline in addition to numerous other products such as heating oil..\n\nIf you can get to the web,\nhttp://www.petroleum.org/petrokids/petroperbbl.htm\nhas many interesting numbers related to your question.\n\nBest, Dick Plano, Professor of Physics emeritus, Rutgers University\n=====================================================\nBernie,\n\nMost of us know that the standard measure for petrol products, crude, light\nsweet etc... is the BBL (barrel).  This is exactly equal to 42 gallons.\nWhether it is milk or molten uranium or gas or crude oil...1 BBL (barrel) is\n42 gallon (US)\n\nI do not know the exact ratio of octane 87 gas to brent oil, light sweet\nblend, or crude oil.  This is because "OIL" is made up of many constituents.\nIt has many long changed hydrocarbons that determine its energy content.\nRefineries of the OPEC nations, or just in general already know this from\nyears of experience.  In order to not waste any of the crude oil, chemical\nengineers will perform hydro-cracking which will cleave the longer (CRUDEr)\noil chains into smaller more volatile compounds.  Why is this done?  This is\ndone so that while distilling the "OIL" engineers will not be able to\nseparate the oil with greater ease and efficiency.\n\nSomeone once told me that there was a rule of thumb for how many gallons of\n"gasoline" you can get from one gallon of crude.  I don't wish to repeat it\nsince I don't recall which blend it was for.  I hope that I've helped you\nsome even though I haven't fully answered your 2nd question.\n\nRegards,\nDarin\n=====================================================\nMy old CRC chemical handbook has it that a US petroleum barrel is exactly 42 gallons.\n\nCrude oil gets changed into petroleum gas, gasoline, oils, tar, and asphalt.\nThe total volume of the non-gaseous products will be not much different than the crude \nvolume.\n\nWhat percentage do they refine into gasoline? I don't know yet.\nAnything from 30-70% wouldn't surprise me.\nThey have both choices and pressures as to what product to make from crude.\n( See http://www.oiltycoon.com/htp/refining.html)\nA person at www.elitetrader.com/vb/showthread.php?threadid=33287 says it's about 2/3.\nThe other product made from the remaining 1/3 of a barrel gets sold too.\n\nSo that would be roughly 28 gallons of gasoline from each barrel of oil.

Yes, gasoline can freeze.  The liquid in it is partly water, so it would be like freezing alcohol, it won't freeze solid, but will turn really slushy.
