Every six months or 10,000 kilometers. Below are relevant details about Mazda maintenance: Coolant inspection: The coolant level must be appropriate. Service stations recommend replacing coolant every two years, but mixed coolant (especially if water was added during summer) must be replaced annually. Note that products of different brands and specifications should not be mixed. Next is engine oil. Winter demands higher lubrication performance from engine oil. If summer-grade oil is being used, it must be replaced. Any oil that has been used for an extended period, turned black, or lost its adhesive properties should be replaced to ensure smooth engine starts. Switching to higher-octane gasoline: If you normally use 90-octane gasoline, consider switching to 93-octane. Since winter driving environments have lower temperatures, higher-octane gasoline has a higher ignition point and better starting capability.

Last time I went for maintenance at the Mazda 4S dealership, I specifically asked the technician. They recommended the first service for a new car at around 5,000 kilometers or six months, mainly involving an oil change, oil filter replacement, and chassis inspection. After that, regular maintenance is typically every 10,000 kilometers or once a year, but it depends on the model year and driving conditions. For example, Skyactiv engines used in heavy traffic daily are best serviced with an oil change at 8,000 kilometers, while those frequently used for long-distance driving can go up to 10,000 kilometers without issues. It's important to note that brake fluid should be replaced every two years, and changing the cabin air filter before summer each year is particularly practical. Tires should ideally be checked for tread depth every 30,000 kilometers. Don't just focus on the odometer; if the car sits unused for over six months, maintenance is also necessary.

Over the years of driving an older Mazda6, I've learned some lessons: maintenance intervals aren't set in stone. For daily commuting, basic maintenance is typically needed every 8,000-10,000 km, but aggressive driving requires earlier oil changes. Before my Sichuan-Tibet trip last year, I specifically changed to full synthetic oil. Remember to replace coolant at least every two years, especially important in summer. Many people never change transmission fluid until their car's end of life, but automatic models actually require fluid changes at 60,000 km. Brake pad wear depends on driving habits - with my frequent mountain driving with full loads, they wear out around 40,000 km.

After reviewing the official Mazda maintenance manual, several key points were noted. The first maintenance for a new car must be done within 5,000 kilometers, otherwise it may affect the warranty. Regular maintenance cycles are divided into Type A and Type B: Type A maintenance, performed every 10,000 kilometers, mainly involves changing the engine oil and oil filter, while Type B maintenance, around 30,000 kilometers, also includes checking the spark plugs and performing a four-wheel alignment. It is specifically mentioned that turbocharged models require shorter oil change intervals, and the Skyactiv-X engine is recommended to use 0W-20 full synthetic oil. The manual also reminds that every maintenance must include checking the brake fluid moisture content, tire wear condition, and lighting system.
