Mercedes-Benz S-Class can use 95-octane gasoline. Automobile engine compression ratio: For cars with a compression ratio between 8.0 and 8.5, 92 or 95-octane gasoline should be used; for those between 8.5 and 9.5, 95-octane or higher should be used; for those above 9.5, 97 or 98-octane gasoline should be used. Introduction to the Mercedes-Benz S-Class: The Mercedes-Benz S-Class is a top-tier luxury vehicle launched by Mercedes-Benz, a brand under the German Daimler Group. In terms of body dimensions, the Mercedes-Benz S-Class measures 5209mm in length, 1872mm in width, and 1473mm in height, with a wheelbase of 3165mm. The Mercedes-Benz S-Class is equipped with bi-xenon headlights, with novel-looking turn signals that make the vehicle more eye-catching. The uniquely styled taillights are very dynamic, and since the turn signals, taillights, and brake lights use striking LED technology, they form a unique visual signature.

As a long-time Mercedes-Benz S-Class owner, I find that using 98-octane gasoline is most suitable. The S-Class engine is quite advanced with a high compression ratio. Using lower-octane fuel can easily cause knocking, which affects performance and may even lead to engine damage. I usually fill up with 98-octane, and I notice quicker starts, smoother acceleration, and better fuel efficiency on highways. I've occasionally used 95-octane, but the car would have slight vibrations, so I don't recommend long-term use. The manual suggests using 97-octane or higher, and 98-octane is commonly available at Chinese gas stations. Fuel quality is also crucial—choose reputable gas stations to avoid substandard fuel, making maintenance easier and preventing extra repair costs in the future. Remember to check the label inside the fuel tank cap for confirmation.

Where is the engine number of the Tharu located?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. You can also check the engine number on the car purchase invoice; the factory certificate includes the engine number; for commercial vehicles, the operating permit can be used to query the engine number; the vehicle purchase tax payment certificate contains the engine number; the public security authority's registration records have the engine number; the vehicle insurance card lists the engine number. The simplest and most direct method is to check the vehicle registration book or the vehicle's driving license. The engine number is like a person's ID number, representing each vehicle. It stores very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or company conventions, and the engine's attributes, used to indicate the manufacturer, specifications, performance, characteristics, technology, purpose, and batch of the engine, such as fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer's range, and engine models can be the same. The engine number, however, refers to the production number of the engine, with each engine having a unique number. Composition of the vehicle engine number: Front part: Includes the product series code, generation symbol, and regional or company code, which the manufacturer can choose as needed, subject to approval and filing by the industry standardization unit. Middle part: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Rear part: Comprises symbols for structural features and usage characteristics. Tail part: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same series, the manufacturer selects an appropriate symbol. The rear and tail parts can be separated by a hyphen.

What Causes Water Dripping Under the Car Chassis?

Water dripping under the car chassis can be caused by exhaust pipe condensation, body drainage holes, or air conditioning drainage pipes. The details are as follows: Exhaust Pipe Dripping: When the combustible air-fuel mixture burns in the engine cylinders, it produces carbon dioxide and water. The water vapor discharged from the engine condenses into liquid water after passing through the catalytic converter, muffler, and exhaust pipe. Under the airflow generated by high-speed engine operation, the liquid water is expelled with the exhaust gases from the exhaust pipe, resulting in dripping or spraying water from the exhaust. Body Drainage Hole Dripping: There are gaps and layers between the body and chassis steel plates. To prevent rainwater accumulation and rust, drainage holes are designed in certain areas of the body and chassis to allow rainwater and melted snow to drain quickly. Drainage holes are usually located near the windshield wipers, where rainwater flows out through guide plates. Door drainage holes are typically hidden under the door seals at the bottom of the door panels, primarily to drain rainwater that seeps into the door interior through window gaps. Air Conditioning Drainage Pipe Dripping: During summer, air conditioning is used frequently. When the AC is operating, condensation forms in the evaporator of the system. Normally, this condensation is drained out of the vehicle through a dedicated drainage pipe. If the pipe is clogged or bent, the water cannot drain properly and may leak onto the floor mats inside the car.

Does transmission fluid need to be changed after three and a half years of use?

Transmission fluid needs to be changed after three and a half years of use. For manual transmissions, the fluid should be replaced approximately every two years or 80,000 kilometers, while automatic transmissions require replacement every two years or 60,000 kilometers. Below are the signs indicating the need for transmission fluid replacement and the hazards of prolonged neglect: Signs that transmission fluid needs replacement: If the transmission fluid shows signs of deterioration, such as turning black, becoming viscous, or emitting an unusual odor, it should be replaced immediately. Additionally, if the transmission frequently experiences issues like rough shifting, slipping, lack of acceleration power, or abnormal noises, it is recommended to change the transmission fluid. Hazards of prolonged neglect in changing transmission fluid: Long-term failure to replace transmission fluid can alter the pH level of the fluid, leading to corrosion of the transmission gears. Moreover, prolonged use of old fluid increases its viscosity, preventing it from effectively lubricating the entire gear mechanism in a timely manner. This can result in overheating of gears, abnormal wear of clutch plates, and other issues. The most direct symptoms include increased shifting jerkiness, longer shifting intervals, lack of power during cold starts, and vibration of the gear lever.
