What items are included in the fourth car maintenance?

Car fourth maintenance involves replacing the oil filter and gear oil, cleaning the air filter, and conducting various inspections. In addition to regular maintenance and oil changes, replacing the spark plugs is recommended. It is particularly advisable to replace the original spark plugs at around 20,000 kilometers. Upgrading to platinum or iridium spark plugs of the same model is a good choice. Here is more information about car maintenance: 1. Perform a major maintenance every 20,000 to 30,000 kilometers or every two years. 2. Major maintenance typically includes replacing the oil filter, fuel filter, and coolant. These three components have a significant impact on the vehicle. If any issues arise and are not addressed promptly, they may cause more severe damage to the car.

My car just had its fourth maintenance, sharing the experience. At 25,000 kilometers, the service at the repair shop included changing the fresh engine oil and oil filter to keep the engine running smoothly, replacing the air filter because of heavy city dust for healthier breathing, rotating and aligning the tires to ensure even wear and extend their lifespan, checking the brake pad thickness to confirm they're still within the safe range (no replacement needed) but testing the brake fluid concentration to prevent deterioration, the spark plugs were due for replacement but my car's condition is good so it was postponed to next time, testing the lighting system (headlights, taillights, turn signals all working) to ensure safe night driving, checking the coolant level with no leaks found, and additionally tightening the chassis bolts to prevent loosening. It cost a little over 400 yuan in total, which I think is quite worthwhile as the car drives more securely with reduced risks.

I enjoy tinkering with cars and doing things myself. The fourth maintenance at 25,000 kilometers involves many items. Essential replacements include engine oil and oil filter to protect the engine core, and a new air filter to improve intake efficiency. Tire rotation and alignment are necessary to maintain balance and prevent uneven wear. Brake components should be checked for thickness and oil quality, replacing them if needed. Spark plugs need to be renewed to ensure stable ignition and avoid shaking. The cooling system should be inspected for leaks, and suspension bolts should be tightened to prevent strange noises. Use tools to test the electrical system to ensure it's functioning properly without short circuits. The entire process was done by myself, costing 400 yuan for parts and taking three hours. It saves money and increases knowledge. Good daily maintenance leads to fewer long-term issues.

For my Porsche's fourth maintenance, I carefully selected only essential services to save money. Changing the engine oil and filter is a fundamental must-do to protect the engine. I saved a hundred yuan by cleaning the air filter instead of replacing it. Tire rotation was done for free to check wear and alignment for safety. The brake system was thoroughly inspected, focusing on pads and fluid to prevent major repairs later. Spark plugs were deferred until the next service. Fluid levels like brake fluid and coolant were checked and topped up if low to prevent emergencies. The total cost was just over 300 yuan – highly cost-effective for keeping the car running smoothly while minimizing unnecessary expenses.

The core of the four maintenances lies in driving safety, and I emphasize this aspect. Checking the brake system includes pad thickness, oil level, and quality to ensure reliable braking and prevent accidents. Tire rotation, wear, pressure, and alignment checks improve grip and stable steering. Testing all lights, including headlights and taillights, ensures high visibility at night. Inspecting the suspension and shock absorbers ensures smooth cornering. Sufficient coolant prevents engine overheating. Changing the engine oil is basic maintenance. These key items should not be overlooked. Spending a total of 450 yuan brings peace of mind and avoids potential hazards.
