The fuel tank capacity of the Mercedes-Benz E300 is 66 liters, with a reserve tank of 8 liters, and it generally uses 95-octane gasoline. Before refueling the vehicle, the engine and all power sources inside the car should be turned off to avoid sparks interacting with gasoline, which could lead to fires or even more serious accidents. Maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for oil leaks at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, ensure that the ventilation holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving. If the owner wants to know the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates that the fuel is almost empty, and when it is near F, it means the fuel level is sufficient.

I've been driving a Mercedes-Benz E300 for a while now, and its approximately 66-liter fuel tank proves quite practical for daily use. Based on my experience, a full tank can last around 300-400 kilometers in city driving, while on highways, it's more fuel-efficient, exceeding 500 kilometers. I often notice how tank size affects travel plans—for instance, the 66-liter capacity means one less fuel stop during weekend getaways. Fuel consumption varies by driver; mine averages about 12L per 100km. I recommend using 95-octane gasoline to keep the engine clean, and don’t overlook tank inspections—regular sediment cleaning prevents performance issues. Driving habits matter too; smooth driving saves more fuel than sudden braking. Overall, a 66-liter tank strikes a reasonable balance between range and economy for mid-to-large-sized cars.

Are there regulations for car license plate screws?

There are regulations for car license plate screws. The fixing screws for car license plates are required to use M6 specification bolts. According to the "Motor Vehicle Safety Technical Inspection Items and Methods," during the registration inspection, the license plate and its installation must also meet the following requirements: 1. The vehicle should be equipped with front and rear license plate boards (frames) that meet the installation requirements for license plates, but motorcycles only need to have a rear license plate board (frame) that meets the installation requirements. The front license plate board (frame) should be located in the middle or right side of the front (according to the direction of the vehicle's movement), and the rear license plate board (frame) should be located in the middle or left side of the rear. 2. The license plate should be directly and securely installed on the vehicle using M6 specification bolts. 3. For vehicles manufactured on or after March 1, 2016, each license plate board (frame) [except for the front license plate board (frame) of three-wheeled vehicles and the rear license plate board (frame) of motorcycles] should have four license plate installation holes to ensure that the license plate can be directly and securely installed on the vehicle using M6 specification bolts.

How Does the Tire Pressure Monitoring System Work?

The working principle of automotive tire pressure monitoring can be divided into two types, as detailed below: 1. Direct Tire Pressure Monitoring. The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It then transmits the pressure data from inside the tire to a central receiver module via wireless transmitters, displaying the pressure data for each tire. When the tire pressure is too low or there is a leak, the system automatically triggers an alarm. 2. Indirect Tire Pressure Monitoring. The working principle of indirect tire pressure monitoring is: when the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotational speed compared to other wheels. By comparing the differences in rotational speeds between tires, the system monitors tire pressure. Essentially, the indirect tire pressure warning system relies on calculating the rolling radius of tires to monitor pressure. 3. Characteristics of Both Systems. Each type of tire pressure monitoring system has its pros and cons. The direct system offers more advanced features, enabling real-time measurement of the actual instantaneous pressure inside each tire and easy identification of the faulty tire. The indirect system is relatively cheaper to implement, as cars already equipped with 4-wheel ABS (each tire equipped with a wheel speed sensor) only require a software upgrade. However, the indirect system is less accurate than the direct system, cannot pinpoint the faulty tire, and involves extremely complex calibration. In certain scenarios, such as when both tires on the same axle have low pressure, the system may fail to function properly.

How often should the tires on a Hyundai Elantra be replaced?

Under normal driving conditions, Elantra tires should be replaced when they reach the lower limit of usage, which is 60,000 kilometers or 3 years. In fact, the lifespan of tires is closely related to many factors, such as climate, road conditions, driving habits, installation, maintenance, and more. The following situations also warrant tire replacement: 1. Bulging or deformation: Bulging or deformation of a tire is a very dangerous condition. If such issues are found, it's best to take the car to a professional repair shop for inspection immediately. In most cases, tire replacement is recommended. These issues indicate that the internal metal coils of the tire have deformed or broken, and continuing to drive could lead to a blowout. 2. Severe wear: Each tire tread groove has a wear limit indicator, which is about 2mm thick. It is recommended to replace the tires when the tread thickness wears to 4mm above the limit indicator, or about 6mm from the deepest part of the groove. 3. Multiple patches: One or two patches won't affect tire use, but after more than three patches, it's advisable to replace the tire for safety reasons. At high speeds, the temperature inside the tire rises, and even well-patched tires with excessive damage can increase the risk of failure. 4. Sidewall puncture: A puncture in the sidewall is indeed more dangerous than one in the tread. If the damage is located below the tire marking near the wheel rim edge, the tire must be replaced because the steel wires in this area are very weak and almost impossible to repair.

Can Air Filters Be Reused?

Air filters can be reused, but replacement is recommended. Using compressed air to blow or washing with water can remove thick accumulated dust, but it is difficult to clean the dust trapped inside the paper. The function of an air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders and preventing floating dust from being sucked into the engine, which accelerates wear on the piston group and cylinders. According to the vehicle's maintenance manual, the air filter should generally be replaced every 10,000–20,000 kilometers or during every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of throttle sludge. The position of the air filter varies depending on the intake system and engine structure, typically located in the air cleaner on the engine's intake pipe. There are two types of air filters in vehicles: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of wire mesh. Air filter: A type of filter, also known as an air cartridge, air cleaner, or element. It is primarily used in engineering vehicles, automobiles, agricultural machinery, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust particles can enter the cylinders, accelerating wear on the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles, ensuring sufficient and clean air enters the cylinders. A dirty air filter: Using an excessively dirty air filter while driving can restrict engine airflow, leading to incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The automobile air cleaner is a device that removes particulate impurities from the air, consisting of one or more filter components. Its main function is to filter out harmful impurities from the air before it enters the cylinders, reducing early wear on the cylinders, pistons, piston rings, valves, and valve seats. Thus, air must pass through the fine filtration of the air cleaner before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if minimal dust and minor clogging are found, it can be cleaned by blowing high-pressure air from the inside out and reused. Excessively dirty air filters should be replaced promptly.
