Calculation method of car fuel consumption: The fuel consumption per 100 kilometers is equal to the volume of a certain amount of fuel (liters) divided by the distance the car can travel (kilometers) under that fuel amount, multiplied by 100. If a car consumes 4 liters of fuel and can travel 50 kilometers, then the car's fuel consumption per 100 kilometers is calculated to be 8 liters, which is commonly referred to as "8 liters of oil". Methods to reduce fuel consumption: 1. Correctly adjust tire inflation pressure: Tire pressure that meets the requirements can reduce the rolling resistance of the wheels and lower fuel consumption. In addition, when the tire pressure is slightly higher than the specified value by +0.2 bar, fuel can also be saved. 2. Moderate use of in-car auxiliary electrical equipment: Using certain electrical equipment will significantly increase fuel consumption, such as the cooling function of the air conditioning system. If the heating purpose has been achieved, the seat heater should be turned off in time. When there is no fog or ice on the rear window, the window heater should be turned off in time. 3. Correct use of gears: Match the speed with the appropriate gear, do not drive at high speed with low gear or low speed with high gear. Shift gears in advance, and the speed corresponding to the gear should be appropriate. Do not drive at high speed with low gear or low speed with high gear.

I usually drive an economy car for commuting, with an average fuel consumption of about 7 to 8 liters per 100 kilometers in the city, and it drops to around 6 liters on the highway. During rush hour traffic jams, the fuel consumption can soar to over 10 liters, which really hurts the wallet. To save fuel, I recommend developing good habits: avoid sudden acceleration and braking, maintain a steady speed; regularly check tire pressure; reduce unnecessary weight in the car; don’t overuse the air conditioning; and use cruise control more often. These small adjustments can reduce fuel consumption by 1-2 liters, saving a significant amount of money in the long run. Of course, as the car ages, fuel consumption may increase, so older vehicles should have their spark plugs and filters checked. Everyone’s driving style is different, so fuel consumption varies from person to person—check your car’s data first and adjust accordingly.

Can vehicle inspection be applied for on 12123?

Vehicle inspection can be applied for on 12123. Original registration vehicle management office: To issue a vehicle inspection entrustment letter, it is necessary to go to the original registration vehicle management office. If the entrustment letter for out-of-town vehicle inspection is not processed, vehicles registered elsewhere cannot undergo normal annual inspection. However, when processing the entrustment letter for out-of-town vehicle inspection, the vehicle owner does not necessarily have to go in person; relatives or friends can handle it at the original registration location and then mail it back to Liaocheng. Vehicle inspection submission: After completing the entrustment procedures for vehicle inspection, the owner should drive the vehicle to the inspection hall next to the vehicle management office for on-site testing.

Will Low Tire Pressure Cause a Blowout?

Low tire pressure does pose a risk of a blowout. The hazards of excessively low tire pressure include: 1. Shortening the lifespan of the tire; 2. Increasing the friction coefficient with the road surface; 3. Creating factors that compromise driving safety, such as making the vehicle prone to veering off course; 4. Increasing the movement of various parts of the tire, leading to excessive rolling and abnormal heat generation; 5. Multiplying the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength; 6. Accelerating rubber aging, breaking the cord, and hastening wear on the tire shoulders. Methods to address excessively low tire pressure are: 1. Using an onboard air pump to inflate the tire; 2. Parking the vehicle in a safe area and replacing it with a spare tire.
