A mature old driver will not only save money on the fluctuating oil price, but also look for reasons from himself. Obviously they are all the same car, commuting to work normally, why is my fuel consumption higher than his?
In fact, in addition to the fuel consumption of the car itself, it is inseparable from the driving habits of the owner. If you find that your car is not as fuel-efficient as the official says, or even very fuel-intensive, then there may be a problem with your driving behavior!
Bigfoot throttle + bigfoot brake. Fuel consumption is so high that you are afraid, in the process of driving, some car owners are accustomed to slamming on the accelerator to accelerate violently, need to slow down or stop and then brake to the real. In fact, this will not only bring certain driving safety hazards, but also increase fuel consumption, and the rest of the companions are also prone to motion sickness! When slamming on the throttle, the engine speed increases rapidly, the amount of fuel injected suddenly increases, and then the sharp brake and restart, invisibly increase a lot of fuel consumption.
Therefore, if there is no emergency, try to keep the vehicle running at a uniform speed, accelerate slowly, safe and fuel-efficient. Resistance increases during frequent lane changes and turns, and vehicles are more fuel-intensive when turning than driving in straight lines. Frequent lane changes are mostly overtaking and paralleling, which increases fuel consumption and increases the probability of accidents. When encountering traffic jams, you should queue up in an orderly manner and avoid congestion, so that it is more efficient to pass.
Speeding and speeding usually occurs on highways, and the continental highway usually has a speed limit of 110 to 120 km/h, but many vehicles will exceed this speed. When driving at high speed, the engine should increase the amount of fuel injection to maintain the speed, and the wind resistance will also increase, if you add the speeding penalty, it is really a loss. In fact, the car is economically fast at 80 ~ 90km / h, and speeding not only increases fuel consumption, but also brings great safety risks.
Drive at high speed in low gear. This error mainly occurs in the novice owners of manual models, due to unskilled operation, often in the low gear deep acceleration pedal, resulting in a sharp increase in engine speed, fuel consumption also increased. Therefore, when opening a manual gear vehicle, it is necessary to replace the gear with the corresponding speed in time, and it is recommended that the speed be lower than 20km/h hang 1 or 2 gears, 20~50km/h hang 3 gears, 50~70km/h hang 4 gears, and 70km/h above 5 gears.
The tire pressure is too low. This is the most overlooked detail, and many car owners do not have the habit of checking tire pressure. In fact, if the tire pressure is too low, the friction area with the ground will increase, so to overcome greater resistance, fuel consumption will naturally come up. Therefore, daily checking the normal condition of tire pressure is also a way to save fuel.
Without timely maintenance, fuel consumption will rise in a straight line. Car maintenance is also very important, if not maintained in time, will be derived from a series of problems, even failures, and fuel consumption is not timely maintenance caused by a car problem. According to statistics, the oil is not changed, increase the fuel consumption by 2%, do not change the air filter, increase the fuel consumption by 10%, the air filter is more important than the oil, the fuel consumption is more important, the spark plug, the carbon deposit in the cylinder is the most serious, almost will increase the fuel consumption by 30%.
