Every day, subject to a number of questions, most of the problems newsroom in the background the first time responded. But to be honest, some not so exhaustive reply. Obviously this is not good, it will be part of the "typical problems" taken out, detailed interpretation, but also be sent to the editorial department to give you a little welfare.

       Q: When it is necessary to refuel fill it? Come on how best to save money?

       1, When to refuel?

       Do not wait until the fuel when the fuel gauge lights, fuel pump is required by gasoline tank cooling, prolonged low oil level may result in overheating of fuel pump; additional oil is low, the fuel pump also easily inhaled impurities bottom of the tank, causing oil Road congestion. Preferably between 10-30% when oil will go to refuel.

   About time, some oil refueling night stand will be relatively favorable prices, the highest discount rate can reach 0.5 yuan / liter. However, this offer has not every petrol station, you need to find out about in advance. As for the problems caused by the temperature difference between day and night thermal expansion and contraction of gasoline, because the depot is under the ground, the temperature difference is much smaller than the air temperature difference, so the volume change of this deviation can be ignored.

       2, The number of refueling appropriate?

       If the long-term urban driving, then you can Do not fill the tank, added into 7,8 or less is enough. Because each additional 20 kg vehicle weight, fuel consumption increased by 1%, this is usually the fuel consumption may not see it, but a year down can save a lot, and can even save a tank of fuel. But do not fill up the number of times the cost of fuel will increase, if you need to detour to the gas station, or often need to line up at the gas station, it would be wasted. After all, when a detour is idling and queuing takes fuel, not as a direct fill.

       Also on the highway gas station density is much lower than the urban areas, the maximum distance between stations may be more than 100 kilometers, and is likely to encounter some petrol stations closed, in order to avoid the embarrassment of running out of oil, so the highway or fill up as well.

       3, How good settlement?

       Some people say that money count the words (plus 100 yuan a whole 150 yuan a whole), easily rounded, virtually lost part. But as the unit of measure in liters is only suitable for fuel card or credit card. If you use cash, there is no way to find a gas station points (0.01 yuan) to you, unless you always use the whole ten liters as a unit, and do not mind holding a pile of coins, or otherwise honestly Renminbi integer count it .

       4, Refueling tips

       I believe many people have encountered this kind of embarrassment, when refueling tanker with oil filler found not on the same side. If hatchback, just keep too far away, the problem is not great; but if it is the sedan, the rear fuel pipe to bypass relatively trouble some, they might also focus on the new line to another. To avoid this trouble, you had better look at the owner of the oil filler position. If you often can not remember, the best way is to look at the fuel gauge on the dashboard indicator arrow is in the direction indicated by the fuel filler.
