The main content of secondary car maintenance is as follows: 1. Key focus: Centered on inspection and adjustment, in addition to performing primary maintenance tasks (replacing the three filters: oil filter, fuel filter, and air filter), it also includes inspecting and adjusting safety components that are prone to wear or deformation after a certain period of use, such as steering knuckles, steering arms, brake shoes, and suspension. 2. Others: Removing and inspecting tires, performing tire rotation, checking and adjusting engine working conditions and exhaust pollution control devices, etc. These are vehicle maintenance tasks performed by repair enterprises.

I've been driving for years, and a secondary maintenance service is like giving your beloved car a thorough check-up to ensure it's in top shape for long-distance trips. The core tasks include changing the engine oil and oil filter to keep the engine running smoothly, as well as a comprehensive inspection of the braking system to check for wear on the brake discs and pads—replacing them early if issues are found saves hassle later. Tire pressure and tread depth must also be checked to avoid dangerous skidding from worn-out tires. The chassis needs lubrication at key joints to prevent rust and unusual noises. Electrical systems, such as battery voltage and headlight brightness, should be tested to ensure nighttime safety. The cabin air filter should be cleaned or replaced to maintain good air quality inside the car. During every maintenance session, I also check the coolant level and replace the antifreeze before winter arrives, ensuring my car remains reliable year-round, extends its lifespan, and reduces repair needs.

As a car owner who always prioritizes driving safety, I believe the greatest value of secondary maintenance lies in hazard prevention. It thoroughly checks braking performance to ensure timely stops in emergencies; meticulously examines tire conditions to prevent skidding caused by insufficient tread; reinforces the chassis to prevent loose parts from affecting handling; and adjusts lighting to ensure adequate illumination in rainy or foggy conditions. Critical fluid levels such as brake fluid and coolant must be confirmed to have no leaks, as leaks could burn out components and lead to accidents. Electrical aspects include testing the battery to prevent breakdowns on the road. I always say that regular maintenance is like buying insurance for safety, avoiding unexpected incidents that could harm both finances and well-being.

From a cost-saving perspective, secondary maintenance is truly a wise choice. Primarily changing the engine oil and filters, spending a few dozen dollars can save thousands on engine repairs; simultaneously replacing the air filter improves fuel efficiency, reducing fuel consumption and saving money; checking the wear level of brake pads and replacing them early avoids the high cost of replacing the entire brake disc; inspecting tires and replacing them when worn out saves on major repairs. Lubricating the chassis joints to prevent rust also reduces repair costs. Although these investments cost a bit each month, they can extend the car's lifespan by several years, making it a very cost-effective decision.
