    Fuel

    Hi,
    Need to knw if this a fact or a myth :-

    Filling fuel early in morning gives you denser fuel with more molecules to burn hence increasing the mileage of your bike...!

      the morning time the fuel is cold compared to afternon or evening
      since liquid expands on theating there may be a difference of 2 or 3 ml beteween morning and later
      therefore its better to fuel in the morning and night than any other time of the day

        ^^^ Hearing this for first time I've always obtained the same FE no matter what time of the day I fill the fuel. Need to see if there're some interesting facts coming out!!!

          Same here, since we have a puny 10+ liter fuel tank we do not notice any difference I suppose.

            its true... but 3-4 ml per litre is too little to make a difference in FE

              Sounds strange but this is fact... You get better mileage if you fuel in morning. But we don't notice it. Any comment from someone owning an RX100 or sumthing similar would help better, as the diffrence between both situations (morning & other daytime), will be countably clear in their case.

                I ve read the same myth some where else also. Not sure where. But as HarishK pointed out, the difference is negligible because of the puny tanks. Only trucks and buses which fill up their tanks with a lot of diesel can appreciate the difference. For everyone else, its negligible.

                    As i heard if you go to fill petrol early in morning , you will not get quantity as on meter as the pump is just started so more air will comes with petrol .

                      I'm getting consistent 45kmpl+ mileage with my r15. The only thing I'm cautious about is I fuel up ONLY in the morning and don't rip hard till about 300-400 meters on a cold engine. Usually keep the tire pressure at 30-35 which is 2psi above the factory recommended so that might be a factor.

                      I don't ride slow. I'm not suicidal so I don't get crazy when dealing with dense traffic but on every empty stretch I'm 100+ everytime.

                      Can anyone give me an explanation about the unusually high mileage? Most my friends get 36-38kmpl.

                      My best bet is my practice of tanking up in the morning.
                      A good long ride can clear your mind, restore your faith, and use up a lot of fuel.

                        The 'myth' of refueling in the morning to get good mileage has been debunked by many across the world. It doesn't matter if you own a car or a bus or a truck or a plane

                        Besides fuel is stored underground and is already at a much cooler temperature than the outside throughout the day. So it is usually pretty down there to really affect mileage.

                        @Parth: You overinflate your tyres and that could result in better mileage. I too get a slightly higher mileage on my over inflated michelin sirac as compared to manufacturer specified figures.

                          I even read somewhere that filling up the tank fully in one go is a good practice rather than filling it up frequently. I follow both the things, filling up in night or morning n also fully at one go.N refill it only when there's a small amount of fuel left in the tank. I prefer Shell Super or Speed (and rarely normal unleaded petrol).
                          I hav been observing a decent mileage, mostly when filled with Shell Super. I I must say Shell is the best.. Extra litres at a bit extra cost is worth.

                            The little change in the volume of the fuel doesn't matter, since it will be a very little change.
                            Also, some fuel-stations now show the density of the fuel stored, so it might put the fuel accordingly.

                              As everybody said it is just a matter of a 2-3 mls, no big deal out of it. Though it will be good for the trucks if they tank up say >100lit of fuel. but still it will be hardly noticable.
