Occasional early maintenance does not have any negative impact on the car. Introduction to Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Maintenance Scope: Modern car maintenance mainly includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. Purpose of Car Maintenance: It aims to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life.

I've been driving for over a decade and have always maintained the habit of early maintenance. During the first few years with a new car, I changed the engine oil every 5,000 kilometers, which was 1,000 kilometers earlier than the manual recommended. This significantly improved the engine's condition, making cold starts particularly smooth. In heavy city traffic, engine oil deteriorates faster, so changing it early helps protect internal components. However, there's no need to go overboard—some friends service their cars every 3,000 kilometers, which is a waste of money. For frequent drivers like me, doing a minor service a week or two early is cost-effective and helps avoid expensive major repairs later on.

Having worked in the automotive industry for many years, I've seen numerous comparisons of customers' car conditions. Vehicles that undergo maintenance ahead of schedule indeed have cleaner engine internals with noticeably less carbon buildup. Especially for owners who frequently drive on highways, early oil changes can mitigate the effects of oil degradation caused by high temperatures. Turbocharged models require even earlier attention, as the turbo bearings operating at high temperatures need fresh oil for protection. However, be cautious not to be misled into excessive maintenance—some businesses promote overly frequent service packages that are unnecessary. Normally, advancing maintenance by around 500 kilometers is quite appropriate, and it also provides an opportunity to inspect often-overlooked components like brake pads and tires.

My old car has run 150,000 kilometers, and the secret is always doing maintenance ahead of schedule. Last time I changed the transmission fluid early, and the gear shifts have been smooth ever since. My friend followed the manual and waited until the maximum mileage for maintenance, and now the engine noise is terrifyingly loud. Basic maintenance done early doesn't cost much, but it saves a lot of worry—no need to constantly fear breaking down on the road. Especially for things like air filters, if you drive near construction sites, changing them early never hurts. With car repairs being so expensive these days, early maintenance is like buying insurance.
