B maintenance is performed at 20,000 kilometers, requiring the replacement of engine oil, oil filter, and air filter, along with an inspection of the cabin air filter. At 30,000 kilometers, the engine oil and oil filter screen should be replaced. The purpose of car maintenance: To keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle servicing. Contents of minor maintenance: Minor maintenance generally refers to the routine maintenance items performed at the manufacturer-specified time or mileage to ensure vehicle performance. It mainly includes replacing the engine oil and oil filter. Contents of major maintenance: Major maintenance refers to the routine maintenance performed at the manufacturer-specified time or mileage, which includes replacing the engine oil, oil filter, air filter, and fuel filter.

I previously owned a Mercedes-Benz B-Class for several years, and maintenance requires careful attention—regular servicing helps avoid major issues down the line. Basic items include changing the engine oil and oil filter every 10,000 km to keep the engine running smoothly. The air filter should also be inspected and replaced to prevent restricted airflow, which affects performance. Safety-wise, brake system checks are crucial, including inspecting disc and pad wear and replacing brake fluid to ensure reliable stopping in emergencies. Tires should be checked every 5,000 km for tread depth and pressure to avoid blowouts or loss of control. Long-term maintenance includes replacing spark plugs every 40,000 km for better fuel efficiency, as well as regularly testing coolant and battery levels to prevent breakdowns. A friend mentioned that computer diagnostics are particularly important for the Mercedes B-Class—early detection of electronic faults can save on repair costs. Lastly, follow the manual for Service A and B maintenance, and choose a reputable workshop.

As an average office worker, I find the maintenance costs for my Mercedes-Benz B-Class quite manageable, but it's important not to slack off. For basic maintenance, I always start with an oil change, replacing the filter along with it—it's cost-effective and delivers noticeable results. The air filter tends to get dirty quickly, so I check it annually to prevent engine blockage. Brake pads and fluid are replaced every two years—safety comes first, especially when driving in rainy conditions. Tires are crucial for family use; regular rotation and balancing can extend their lifespan. There are many signs before a battery dies; if the engine starts slowly, it's time for a check-up. Experienced drivers know to replace spark plugs at the recommended mileage—it saves fuel and reduces hassle. My personal advice is not to delay maintenance; the manual suggests Service A every 10,000 km and Service B every 20,000 km. Opting for certified service centers ensures peace of mind and avoids high post-warranty costs.

Having driven many cars, the maintenance focus for the Mercedes-Benz B-Class is on prevention. Key tasks include changing the engine oil and oil filter to ensure lubrication; replacing the air filter regularly to avoid dust buildup; essential brake-related inspections such as pads and fluid; tire checks to prevent uneven wear; and replacing spark plugs as per the manual to save on repairs. An additional reminder: coolant leaks pose significant risks, and battery life should be considered for replacement after three years. Computer diagnostics can economically identify fault codes early. It's recommended to conduct self-checks every six months or have professional maintenance done at a shop, rather than waiting for major issues to arise.
