If you mean engine oils, these are ACEA performance grades:\nA3/B4 Stable, stay-in-grade oil intended for use in high performance gasoline and direct injection diesel engines, but also suitable for applications described under A3/B3.\n \nA5/B5 Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline and car + light van diesel engines designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate viscosity of 2.9 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.

the density keeps on varying \n\nfor eg this \n\n\nThe density of crude oil varies, depending upon the amount of heavy and light components. Typical values, in Kg per cubic meter are:\n\n    * Mexican crude oil 973\n    * Texas crude oil 873\n    * Gasoline 737\n    * Kerosene 817\n    * Diesel 840\n    * Automobile oil 880 - 940\n    * Pure water (at 4°C) 1000

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.

No, not likely. \n\nCoal is formed from (coalified) plant material. Petroleum and natural gas are formed from organic remains of plants, primarily microscopic phytoplankton, and small marine animals called zooplankton. \n\nIn the rare instance that a dinosaur's dead body might have been carried by water into an oxygen poor (anaerobic) environment and quickly buried by catastrophic deposition of shales, there might have been some protein or lipids from that carcass that eventually converted to oil, but it is far more likely that the body of a large organism like a dinosaur would become food for decomposing bacteria and other scavengers long before it had the opportunity to be converted to oil by the process of heat and pressure known as catagenesis.\n\nThere is no truth to the answer that the "traditional theory is that petroleum formed during the same period as dinosaurs" as most of the world's petroleum reservoirs are known to be younger than that, and many are known to be older. One deposit of oil has been found that is only about 4,000 years old. \n\nDr. Thomas Gold's hypothesis of abiotic oil has never been substantiated by any evidence of oil that is NOT from biological sources.  Very few geologists agree with Gold, and none have been able to prove he was correct. There is considerable evidence in the form of molecular structure, isotopic fractionation, and more that proves that little if any oil is from the abiotic mechanism Gold hypothesized. The big problem with Gold's hypothesis is that oil and gas ARE NOT found in igneous rocks, as one answer here suggests.\n\nI'm a petroleum geologist.

pure butane is neutral for sure. And butane, no matter isobutane or just butane, is alkane. Alkane does not dissolve in water since no ionic bond exists in the compound, so measuring its pH does not make much sense.\n\nCarbon and hydrogen have very similar electronegativity, so it's very difficult to remove hydrogen from the carbon chain. It's pka value is around 50.

the quickest way to figure it out i think would be to call a fitting/valve supply house and ask them. the BSI standard you reference deals with manufacturing. i have found some ISO sets that govern this and some API but im not in India and have yet to build anything in that country so i doubt these will help. unless India uses American Petroleum Industry standards.

ah DA petroleum MEANS oil . natral gas is methan and it come from decaing plant and animal matter. its usally found around coal and oil often found at same time coal an oil are from the same thing is why

Long ago, I learned about a qualitative test for borates that goes like this:  you mix a little of the unknown with some methyl alcohol, and add a little H2SO4.  If a borate is present, methyl borate will be formed, and if the mixture is ignited, it will burn with a GREEN flame.  So, just make (or buy) some methyl borate and add it to the naphtha.

That is virtually impossible to answer, as gasoline is a mixture of different hydrocarbons varying from 5 to 10 carbon atoms per molecule.
