I was surprised to know it but had a doubt so I talked to one of the pump technicians and he too accepted it as a fact. I think apart from providing space for the gas generated inside the petrol tank this is yet another reason why we shouldn&#8217;t fill the tank to the brim. Many of us are not aware that the petrol kiosk pump has a return pipe-line (in Pink). When the petrol tank (in the car) reaches full level, there is a mechanism to trigger off the pump latch and at the same time a return-valve is opened (at the top of the pump station) to allow excess petrol to flow back into the pump. But the return petrol has already pass through the meter, meaning you are donating the petrol back to the Oil Dealer.Also only fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the petrol, when it gets warmer petrol expands, so buying in the afternoon or in the evening&#8230;.your liter is not exactly a liter. In the petroleum business, the specific gravity and the temperature of the petrol, diesel and jet fuel, ethanol and other petroleum products plays an important role.A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.<\/p>\n<p>When you&#8217;re filling up do not squeeze the trigger of the nozzle to a fast mode If you look you will see that the trigger has three (3) stages: low, middle, and high. You should be pumping on low mode, thereby minimizing the vapours that are created while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours are being sucked up and back into the underground storage tank so you&#8217;re getting less worth for your money.<\/p>\n<p>One of the most important tips is to fill up when your Petrol tank is HALF FULL. The reason for this is the more Petrol you have in your tank the less air occupying its empty space. petrol evaporates faster than you can imagine. petrol storage tanks have an internal floating roof. This roof serves as zero clearance between the Petrol and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every litre is actually the exact amount.<\/p>\n<p>Another reminder, if there is a petrol truck pumping into the storage tanks when you stop to buy Petrol, DO NOT fill up; most likely the petrol is being stirred up as the Petrol is being delivered, and you might pick up some of the dirt that normally settles on the bottom.<\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<h2>Detailed Analysis<\/h2>\n<p>Before even looking at each claim individually, let&#8217;s get one thing out of the way first: not one of the items listed in any way was put in place to screw over the consumer and make oil companies richer. \u00a0 This seems to be a misconception the author had specifically regarding vapor recovery systems. \u00a0 Aside from the ecological benefits of such systems, if anyone benefited it would be the local filling station owner.  \u00a0And considering the rather high cost of installing and maintaining those systems \u00e2\u20ac\u201c a recent estimate is that the \u00a0<a class=\"norm\" href=\"http:\/\/www.petrolplaza.com\/technology\/articles\/MiZlbiYxNDc5OCYmMSYxJiY%3D\">removal of those systems would SAVE filling stations about $3,000 a year<\/a>.<\/p>\n<p>This newest version starts off with a claim that a mechanism in the pump returns fuel to the underground tank if you fill your vehicle&#8217;s tank too much. \u00a0 It starts off with what is actually a valid premise (\u00e2\u20ac\u0153<em>providing space for the gas generated inside the petrol tank<\/em>&#8221; is sound advice to ensure proper functioning of your vehicles \u00a0<a class=\"norm\" href=\"http:\/\/auto.howstuffworks.com\/evaporative-emission-control-system.htm\">evaporative collection system<\/a>); beyond that, it is well intentioned but pretty inaccurate. \u00a0 Referring to the &#8216;pink hose&#8217; would indicate they are referring to a vapor recovery system, although the same principle can be applied to the \u00a0<a class=\"norm\" href=\"http:\/\/auto.howstuffworks.com\/fuel-efficiency\/fuel-consumption\/gas-pump-full-tank.htm\">simple vacuum system used in nearly all common fuel pumps to flip the filler nozzle off<\/a>. \u00a0 Of course vapor recovery systems are not universally used; in the US they would only be found in areas designated by the EPA as &#8216;<a class=\"norm\" href=\"http:\/\/www.epa.gov\/oar\/oaqps\/greenbk\/index.html\">nonattainment areas<\/a>&#8216;, or in states that mandate use of such systems. \u00a0 With both vapor recovery systems and the normal vacuum controlled shut-off, the vacuum is created by the negative pressure created in the underground tank as fuel is pumped out and into your vehicle. \u00a0 It is not an accessory pump designed to suck fuel back out of your tank \u00e2\u20ac\u201c those would only be found at tank farms on tanks holding tens of thousands of gallons. \u00a0 If you look at the nozzle of the fuel pump, you&#8217;ll notice a small hole. \u00a0 In a \u00a0<a class=\"norm\" href=\"http:\/\/www.husky.com\/husky\/vapor-recovery\/husky-v\/\">pump with a vapor recovery system<\/a>, you&#8217;ll notice a couple of larger holes on either side, or a series of holes all the way around the end of the nozzle. \u00a0 The vacuum created draws air back through those holes. \u00a0 An interruption in the airflow, or having to &#8216;suck&#8217; harder, trips the switch to shut off the pump. \u00a0 Neither system is designed to draw fluid back through the system. \u00a0 Introduction of liquid can actually foul the system. \u00a0 Which is where that first paragraph almost gets it right: \u00a0 hang up the pump when it clicks itself off. \u00a0 \u00a0<a class=\"norm\" href=\"http:\/\/www.epa.gov\/donttopoff\/\">Topping off the tank is bad for your car and bad for the pump and potentially bad for the environment<\/a>. \u00a0 Your vehicle&#8217;s evaporative control system is designed to re-burn vapor, not liquid fuel, and you could damage it and worsen your vehicles fuel economy. \u00a0 The vapor recovery system is designed to pull vapor back into the system, but it can and will simply suck fuel you paid for into the vapor recovery system. \u00a0 And the auto-shutoff on the pump is designed to suck air. \u00a0 Introduction of liquid can foul that system and prevent the shutoff from shutting off, resulting in you getting a shoe full of gasoline. \u00a0<\/p>\n<p><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><br \/>\n<ins class=\"adsbygoogle\"\n     style=\"display:block;

\u00a0 the aforementioned evaporative control systems in automobiles makes vapor recovery at the pump unnecessary.<\/p>\n<p>The science behind the &#8216;fill up in the morning&#8217; advice might seem sound, but in reality it only really matters if you&#8217;re a) getting your fuel from an above ground tank, or b) referring to heating oil delivered by a tanker truck. \u00a0 \u00a0 In the latter case, temperature compensators are used by a number of fuel oil distributors in the US on their delivery trucks, and the invoice will state that volume delivered has been adjusted to the volume of 60 degree Fahrenheit (in the US the reference temperature for petroleum products is 60 degrees F). \u00a0 There has been talk in some US states of implementing temperature compensators on retail gasoline pumps, but so far the math has not made it that imperative. \u00a0 Why? \u00a0 Because underground tanks are 15 to 20 feet below ground. \u00a0 While surface temperatures may vary 10 or 20 or even 30 degrees (Fahrenheit), the temperature inside a double-welled, insulated fuel tank 20 feet below ground might not even vary a couple of degrees from the usual 55 degrees F. \u00a0 The only time it will vary significantly is when fuel is being delivered to the underground tanks by a tanker truck. \u00a0 On a hot day, the fuel from that truck will be warmer and might take a few hours to cool. \u00a0 Other tests noted that there was a \u00a0<a class=\"norm\" href=\"http:\/\/news.consumerreports.org\/cars\/2008\/08\/gas-pump-myth.html\">temperature difference between the first few gallons pumped<\/a>, rapidly cooling to &#8216;tank temperature&#8217;&#8230; because fuel is sitting in the pipes and hoses closer to the ground or in the pump itself between fill-ups. \u00a0 But that was at a test track \u00e2\u20ac\u201c not at a busy station, so probably not an issue. \u00a0 But \u00e2\u20ac\u201c for the sake of argument, let&#8217;s say you live in a terrifically hot climate and happened to stop in the afternoon when the fuel was potentially at its warmest. \u00a0 And let&#8217;s compound that by having the 10,000 gallon tanker truck just having finished refilling the station&#8217;s tanks. \u00a0 Now, let&#8217;s throw all logic aside and say that instead of 60 degree fuel, you&#8217;ve got 85 degree fuel. \u00a0 How much difference does that make? \u00a0 Let&#8217;s say your vehicle has a 20 gallon tank. \u00a0 Instead of pumping 20 gallons of 60 degree fuel, you&#8217;d only get \u00a0<a class=\"norm\" href=\"http:\/\/agriculture.nh.gov\/news\/documents\/weights-fuel-temperature.pdf\">19.708 gallons of 85 degree fuel<\/a>. \u00a0 In a more realistic scenario, the temperature differences noted in real life experiments only varied by a few degrees F. \u00a0 But for arguments sake, let&#8217;s say the tank temp rose to 70 degrees Fahrenheit on a hot afternoon. \u00a0 That same 20 gallons is now a mere 19.884 gallons. \u00a0 At a US $4.00 per gallon, that&#8217;s less than 50 cents. \u00a0 Certainly that&#8217;s important if, like the screed notes, you&#8217;re in the petroleum business and trading in millions of gallons. \u00a0 But is it significant enough for you to alter your schedule or routine?<\/p>\n<p>So far as pumping at low speed&#8230; gasoline evaporation is a given. \u00a0 It&#8217;s going to happen and it&#8217;s going to happen at a fairly predictable rate. \u00a0 The question is this: \u00a0 is the amount you&#8217;re losing to evaporation (regardless of whether the area you are in mandates vapor recovery systems \u00e2\u20ac\u201c again, this has nothing to do with making oil companies richer) by agitating the fuel as you pump it greater than the amount you would lose to evaporation by taking 2 or 3 times longer to pump your fuel? \u00a0 Common sense, folks.<\/p>\n<p>Half full or half empty? \u00a0 I do tell my daughters to not let the fuel gauge drop below  \u00bc tank&#8230; but that&#8217;s more wishful thinking that I won&#8217;t go out in the morning and find my vehicle with the fuel gauge sitting on E. \u00a0 We can always hope. \u00a0 Other than that, the assumption here is that the more vapor in your tank (the less fuel, the more room for vapor) means that the more vapor is potentially lost when you open your gas cap. \u00a0 Which is entirely contrary to another school of thought; never having MORE than a half tank because the reduced weight will improve fuel mileage. \u00a0 Not surprisingly, both are fundamentally wrong. \u00a0 Remember that evaporative collection system in your car? \u00a0 Pretend it&#8217;s not there. \u00a0 Without it, at worst you might lose 1 (one) gallon PER YEAR to evaporation. \u00a0 (Formulas for evaporation can be \u00a0<a class=\"norm\" href=\"http:\/\/www.epa.gov\/ttn\/chief\/ap42\/ch07\/final\/c07s01.pdf\">found here<\/a>&#8230; it&#8217;s for storage tanks, so grab a calculator). \u00a0 With that system, vapor loss is negligible. \u00a0 The half-tank folks are just asking for trouble and chasing rabbits. \u00a0 With our aforementioned 20 gallon tank, the weight we&#8217;d be saving never getting above  \u00bd tank would be a shade over 83 pounds. \u00a0 I could just leave my Basset hound at home and achieve the same result. \u00a0 And before anyone jumps on the math there \u00e2\u20ac\u201c yes, I realize I calculated the weight of about 13 gallons, and I know that&#8217;s more than half of a 20-gallon tank. \u00a0 Because when your gauge reads  \u00bd tank, you&#8217;ve probably actually only got about 1\/3 in the tank. \u00a0 Fuel gauges are non-linear, and that&#8217;s just \u00a0<a class=\"norm\" href=\"http:\/\/autos.aol.com\/article\/gas-gauge\/\">how they work<\/a>.<\/p>\n<p>So far as filling your tank when a truck is filling the underground tanks&#8230; between the filters in place in the underground tanks and the fuel filters in your vehicle, so long as the tanks are properly maintained this is irrelevant.
