How to Check Fuel Level on a Mercedes-Benz Fuel Gauge?

The fuel gauge shows the fuel level in the vehicle's tank. When the needle points to 0, it indicates that the fuel tank is low on fuel. When the needle points to 1, it means the fuel tank is full. If the needle is between 0 and 1, it indicates that the tank is half full. Based on the fuel level, it is recommended to add fuel in a timely manner and not wait until the fuel warning light comes on. Here is some relevant information about the vehicle's fuel tank: 1. Introduction: The automotive fuel tank is the full name of the car's fuel container. Currently, with the development of the automotive industry and the revitalization of the domestic automobile sector, the demand for automotive fuel tanks from major automobile manufacturers has shown a significant upward trend. 2. Design Principle: The design utilizes the heat energy generated by the engine during operation, incorporating a thermal circulation system between the engine, fuel tank, and radiator. The original single fuel tank is redesigned into a combined fuel tank consisting of a main tank and an auxiliary tank.

Mustang: Should You Use 92 or 95 Octane Fuel?

According to the official vehicle manual recommendation, the Mustang should use 95 octane fuel. In addition to checking the appropriate fuel grade in the vehicle manual, the Mustang owner can also find this information on the fuel tank cap, which is usually labeled. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane fuel, while those with a compression ratio between 10.0-11.5 should use 95 octane fuel. However, with the application of new technologies, the compression ratio alone cannot determine the fuel grade—high compression ratios can still be tuned to use lower octane fuel. This is because other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the fuel octane number, the higher the octane value and the better the anti-knock performance. 92 octane fuel contains 92% isooctane and 8% n-heptane, while 95 octane fuel contains 95% isooctane and 5% n-heptane. If the Mustang occasionally uses the wrong fuel grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong fuel grade can have the following effects: For vehicles recommended for low-octane fuel, using higher octane fuel will not cause damage, but the increased octane value alters the fuel's ignition point, leading to delayed combustion in the engine. This reduces both the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended for high-octane fuel, using lower octane fuel can cause engine knocking. Due to the significantly lower octane value, the fuel ignites prematurely during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke. This resistance makes the engine run very unevenly. If the knocking is mild, it may only increase noise without obvious engine damage. However, severe knocking indicates critical engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in extreme cases, cylinder scoring.

Should You Release the Handbrake or Shift to D Gear First When Starting an Automatic Transmission Car?

When starting an automatic transmission car, first shift to D gear and then release the handbrake. It is essential to keep the brake pedal pressed. The order can be reversed without major issues, but it is crucial not to forget to release the handbrake. Starting with the brake pedal pressed can easily burn out the brake pads. If you're a beginner and not yet accustomed to the process, you can release the handbrake first to avoid forgetting it after starting. Whether it's a manual or automatic transmission car, the most important step when starting is to shift into gear first and then release the handbrake. The handbrake serves as the final safety measure. Only after fully engaging the gear and before moving should you release the handbrake—this practice is very safe. When shifting gears, move quickly from P to D to avoid passing through R, which can cause a backlash and harm the transmission. If you engage the gear but do not release the handbrake, all the power output from the engine will be absorbed by the torque converter, causing its temperature to rise sharply. Prolonged exposure to this condition can burn out the torque converter. For dual-clutch transmissions, after engaging the gear, the clutch friction plates will remain in a semi-engaged state. Prolonged semi-engagement can lead to burning out the friction plates, so it's necessary to start moving as soon as possible. Generally, if you don't press the brake pedal before starting an automatic transmission car, it can negatively impact the vehicle's transmission and gear structure. This effect is even more pronounced when the car is parked on an incline.

How Often Should the Fuel System Be Cleaned?

Fuel system cleaning is generally recommended every 2 years or approximately 60,000 kilometers. The steps for cleaning the fuel system are as follows: 1. Clean the fuel tank: Turn off the power, unplug the fuel sensor connector, remove and take out the electric fuel pump or fuel sensor, open the fuel tank cap, remove the filter screen, use a hose to extract the fuel from the tank, leaving about 5~8cm of fuel, then add a certain amount of ethanol or cleaning agent. Connect one end of a plastic hose to an air pump and insert the other end into the bottom of the fuel tank through the fuel tank opening. Use 3MPa air pressure to blow and clean, so that various impurities accumulated at the bottom of the tank, such as dirt, rust, and gum particles, are washed away by the agitated cleaning oil. 2. Clean the electric fuel pump: Use a carburetor cleaner to remove various impurities attached to the fuel pump. For mechanical fuel pumps that can be disassembled, the main cleaning parts are the inlet valve, outlet valve, and oil cup. For aged fuel pump diaphragms, replace them with new ones. For non-disassembled mechanical fuel pumps, replace them with new ones as needed. Replace the fuel sensor float in the tank if it affects the accuracy of the sensor. 3. Clean the fuel injector: Use a specialized carburetor cleaner to clean the oil passages, metering holes, oil surface chamber, atomizing nozzle, needle valve, etc. Replace the polymer plastic fuel float with a copper or stainless steel one. After cleaning, the carburetor should be clean and free of attached impurities. After reassembly, perform operational performance debugging to ensure the engine maintains stable idle speed, smooth transitions between high and low speeds, and no backfire or popping. 4. Clean the fuel filter: For detachable filters, use specialized cleaning oil to clean the oil cup and filter element. Polymer plastic filter elements must be replaced with ceramic or steel mesh nylon fabric filter elements. Replace disposable fuel filters. 5. Clean the electronic fuel injector: The electronic fuel injector of an electronic fuel injection vehicle should be cleaned on a specialized cleaning bench. Use specialized cleaning agents or carbon removers to thoroughly remove carbon particles and stains from the injector. After cleaning, verify the fuel injection quality before reassembly. 6. Clean the fuel supply lines and various filters: Use specialized cleaning oil or a cleaning machine for cleaning. 7. Check the fuel tank breather valve: The fuel tank's intake and exhaust should be unobstructed. If not, the breather valve must be cleared or replaced. 8. Test drive inspection: After cleaning, add ethanol gasoline to the vehicle and start it. Inspect all components of the fuel system to ensure there are no leaks, and check and adjust the operational performance of each part.
