How to save fuel is a timeless topic for driving. Articles about fuel saving are also common. What kind of method is the most fuel-efficient? What kind of method is the simplest? In fact, the fuel economy itself is very simple, as long as we develop good habits, and the accumulated oil will naturally come down, especially in today's fuel prices, good driving habits to create more value in cost savings is very helpful .
Choose the right oil
If you can say that trucks can save anything, motor oil must not be saved. It is recommended that drivers use the grade oil recommended by the manufacturer and purchase it by themselves, but the grade is higher than the manufacturer's recommended oil. Choosing the right oil can minimize engine friction, thereby reducing the engine's workload and helping to improve fuel economy by 1% to 2%. In addition, the operating temperature range of different oils is not exactly the same, and it must be clear before buying.
Minimize air conditioning
According to relevant data, air-conditioning or not, the difference in fuel consumption can reach 1~1.5L/100km; the air-conditioning temperature should be 1 degree Celsius lower, and the fuel consumption difference should be 0.05~0.1L/100km. If the temperature allows, you should try to shake off the window. However, air conditioning is not turned off at any time: when the speed is less than 64km/h, the window is turned off and the air conditioner is turned off; when the speed exceeds 72km/h, the air conditioner must be closed to close the window because the air resistance will consume more than the air conditioner. The fuel does not feel hot when the temperature is adjusted to 26°C, nor does it feel that cold temperatures are not difficult.
Keep air cleaner clean
The dust on the hot summer road is large and the air filter should be cleaned more diligently. When the air filter is clogged with oil, the fuel economy is reduced by 14%, and the engine may be damaged. A clean air filter can improve acceleration. If the air filter is full of dirt, it will increase the burden on the engine, even inflow of impurities, and eventually damage the engine. The United States Environmental Protection Agency (EPA) said that the replacement of severely clogged air filters can increase fuel economy by up to 14%. High quality air filters also help improve vehicle acceleration.
Adjust the proper tire pressure
Under the premise of ensuring security, it is a practice of many old drivers to use more gas. Slightly higher tire pressure does help to reduce fuel consumption, but the other side is easy to puncture. In the winter, it can be tried, but the summer heat can never be, because the summer heat is the most likely season of puncture in the whole year. Many car owners to reduce the risk of hot summer tire bursts, deliberately reduce the tire pressure, this action is also not necessary, in the case of under-inflation, the four tires for each tire pressure drop 1psi, the fuel economy index loss of about 0.3%. It is worth mentioning that do not rely entirely on the tire pressure monitoring system (TPMS) to detect if the tire is under-inflated. It is recommended to use the TPMS once a month.
Tighten fuel tank cap after refueling
Diesel is volatile, especially in summer, so remember to tighten your fuel tank cap after each refuel. According to a report from the Discovery Channel, this situation wastes as much as 560 million liters of fuel each year. Losing or not tightening the fuel tank cap will directly reduce the fuel economy by 1%~2%.
Control speed
It is worth mentioning that speed control. Most car owners think that the speed limit signs on the road are purely for safety reasons. Actually, it also includes considerations of fuel economy. Maintaining proper driving speed is very effective in reducing fuel consumption. Although the optimal fuel consumption speed (or speed range) varies from vehicle to vehicle, when the vehicle speed exceeds 96 kilometers per hour, fuel economy will drop rapidly. At a speed of over 96 kilometers, the extra fuel consumption per 8 kilometers per hour increased by a few cents per liter of gasoline.
