How Many Kilometers Before a Major Maintenance is Needed?

[McJulian]

Generally, vehicles require a major maintenance service after traveling 30,000 kilometers. The major maintenance items include the following: 1. Replace engine oil, oil filter, fuel filter, and air filter; 2. Inspect the braking system for any oil leaks and check if the brake pads are within the specified thickness; 3. Check the wear condition of the engine belt and adjust the belt tension if necessary; 4. Inspect the transmission, drive shaft, and universal joint boot for oil leaks or damage; 5. Check the tread depth, tire pressure, and wear condition of the tires, and perform a wheel alignment if necessary; 6. Inspect the throttle body and idle valve for excessive dirt and clean them if needed; 7. Check the condition of the spark plugs and replace them if necessary, along with a no-disassembly cleaning of the fuel injectors; 8. Inspect the power steering, braking system, and automatic transmission; 9. Test whether the braking force, gear shifting, and steering are functioning normally; 10. Lubricate all relevant parts of the vehicle.

Having driven for many years, I generally recommend a major service every 40,000 to 60,000 kilometers. This includes changing the transmission fluid, brake fluid, coolant, and inspecting key components such as brake pads and the steering system. Why is it necessary to do this regularly? Because accumulated mileage causes these parts to wear out, and if not replaced, the transmission or braking system could fail, posing serious risks. For example, a friend of mine skipped his service, which led to brake failure and nearly caused an accident—the repair costs ended up being much higher. New car manuals may specify more precise intervals; some SUVs, for instance, require more frequent servicing. Driving habits also play a role—cars frequently driven on rough roads or with aggressive acceleration wear out faster. Regular major maintenance extends your car’s lifespan, saving you both hassle and money. It’s best to visit a professional shop every two years or at fixed intervals for a thorough check-up to ensure everything is in good condition.

When it comes to major maintenance, I usually go every 50,000 kilometers to be on the safe side. It includes changing fluids like transmission oil and coolant, plus a comprehensive inspection of the brake and suspension systems. Driving gently might extend the intervals, but frequent highway sprints may require earlier service. I remember once forgetting maintenance, and the engine overheated, leading to a lengthy repair. Maintenance is not something to slack on—investing a little can prevent big troubles. Checking the owner's manual to set up a schedule is the most reliable way to keep the car in good condition, ensuring peace of mind on long trips.

I usually perform a major maintenance service every 45,000 kilometers, focusing on replacing transmission fluid and brake fluid, while inspecting cooling and electrical components. With daily driving accumulating to this mileage, fluids deteriorate and affect performance, so timely replacement prevents critical failures. Combining manual guidelines with personal vehicle usage, urban commuting can allow slight delays, but don't postpone too much.
