What else needs to be replaced besides engine oil?

[MacJade]

Generally, it involves replacing the engine oil with three filters or two filters. The three filters include the oil filter, air filter, and cabin air filter. The two filters consist of the oil filter and air filter. Three filters for engine oil: The oil filter's maintenance interval varies depending on the type of oil used. For mineral oil and semi-synthetic oil, the engine oil should be replaced every 6 months or 5,000 kilometers. For full synthetic oil, it's recommended to change every 1 year or 10,000 kilometers. The air filter is typically replaced annually. The fuel filter replacement interval varies by vehicle model, generally between 30,000 to 60,000 kilometers. Three fluids and three oils: Three fluids: windshield washer fluid, coolant, and air conditioning drain pipe drainage. Three oils: fuel, engine oil, and brake fluid, along with power steering fluid and automatic transmission fluid. Regular preventive maintenance involves inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components. Modern vehicle maintenance primarily covers engine systems, transmission systems, air conditioning systems, cooling systems, fuel systems, power steering systems, etc.

I always replace the oil filter along with the oil change as a standard practice, because residual impurities in the old filter can contaminate the new oil and wear down the engine internals. I also change the air filter regularly; if left unchanged for too long, it can restrict airflow, affecting fuel efficiency and power output. The cabin air filter needs attention too, especially during allergy seasons in spring and autumn—replacing it improves air quality inside the car for a more comfortable drive. Additionally, I check the condition of the coolant and brake fluid, replacing them if discolored or low to prevent overheating or braking failure. I frequently inspect tire wear and spark plug conditions too. Overall maintenance shouldn’t focus solely on oil changes—being thorough helps the car run longer and safer, preventing minor issues from turning into major repairs.

Every time I go for an oil change service, I always replace the oil filter—skipping it would make the oil change pointless, as contaminants would mix back in and damage the engine. The cabin air filter and engine air filter should also be replaced at the same interval, roughly every 10,000 kilometers, otherwise the car's airflow gets restricted and fuel consumption spikes. I also have the technician check if the brake fluid has degraded, replacing it with fresh fluid if necessary to ensure safety. Tires and spark plugs are inspected regularly but don't need replacement every time; always refer to the maintenance manual and avoid exceeding intervals—this saves money, prevents headaches, and avoids breakdowns. Developing these habits keeps the car reliable and gives peace of mind.

When changing the engine oil, I always replace the oil filter as well, otherwise the new oil will quickly deteriorate and wear out engine components. It's also crucial to handle the air filter at the same time—if it's clogged, it can affect power and fuel consumption, and cleaning it improves efficiency. The cabin air filter should be replaced as needed, especially in dusty environments where timely replacement can eliminate odors. Additionally, check the coolant level and top it up if low, though it's not necessary to replace it at the same time. Overall, don't overcomplicate maintenance—filters are key to extending your car's lifespan.

Changing engine oil must be accompanied by replacing the oil filter; otherwise, circulating impurities can damage the engine and shorten its lifespan. It is recommended to replace the air filter simultaneously to ensure clean air intake, improve combustion efficiency, and save fuel. The cabin air filter should be checked seasonally and replaced if noticeable odors are present to improve the environment. I also pay attention to the condition of the coolant and replace it when necessary to ensure cooling safety. For spark plugs or the brake system, refer to the manual guidelines, and do not overlook small details during maintenance to avoid potential hazards.
