4 Answers
In automobiles, the five oils, four filters, and three fluids are as follows: Five oils: engine oil, power steering fluid, transmission fluid, clutch fluid, and brake fluid; Three fluids: coolant, battery fluid, and windshield washer fluid; Four filters: air filter, oil filter, fuel filter, and cabin air filter. The replacement intervals for the five oils, four filters, and three fluids are as follows: 1. Engine oil: mineral oil every 5,000 km, semi-synthetic oil every 7,500 km, and fully synthetic oil every 10,000 km; 2. Power steering fluid: replace every two years or 40,000 km; 3. Transmission fluid: automatic transmission every 40,000-60,000 km, manual transmission every 60,000-80,000 km; 4. Clutch fluid: replace every 40,000-60,000 km; 5. Brake fluid: replace every two years or 40,000 km; 6. Coolant: replace every 20,000 km; 7. Battery fluid: mostly maintenance-free, check during service, no need to top up; 8. Windshield washer fluid: refill when empty, remember to switch to winter-grade antifreeze washer fluid in cold seasons; 9. Air filter: replace every 15,000 km; 10. Oil filter: replace with every engine oil change; 11. Fuel filter: replace every 20,000 km; 12. Cabin air filter: replace every 15,000 km.
I've been driving for over twenty years, so the 'five oils, four filters, and three fluids' are all too familiar to me. The five oils refer to engine oil, transmission fluid, brake fluid, power steering fluid, and differential oil—they need to be changed regularly, otherwise engine wear or brake failure could be dangerous. The four filters are the air filter, oil filter, cabin air filter, and fuel filter; replacing them keeps the car breathing smoothly and running with more power. The three fluids include coolant, windshield washer fluid, and battery fluid—coolant ensures proper heat dissipation, washer fluid keeps the windshield clean, and battery fluid maintains battery life. I check these details every month to ensure a safe journey. Don't wait until something breaks to fix it; maintaining them saves money and hassle. A car is like an old buddy—take good care of it, and it won't leave you stranded. Before long trips, always check these fluids and filters for peace of mind.
As a fun-loving young person, my car is my great companion. What about the five oils, four filters, and three fluids? The five oils are engine oil to keep the engine running smoothly, transmission oil for smooth gear shifts, brake fluid to ensure safe stopping, power steering fluid for light and easy steering, and differential oil to protect the drivetrain. The four filters include the air filter to prevent dust from entering the engine, the oil filter to remove impurities, the cabin air filter to purify the air inside the car, and the fuel filter to keep the gasoline clean. The three fluids are coolant to lower the engine temperature, windshield washer fluid to keep the windows clear, and battery fluid to extend battery life. I service my car every six months, using high-quality full synthetic oil and eco-friendly filters. The car responds quickly and has low fuel consumption. Especially in the era of electric vehicles, filters are being upgraded, and the cabin air filter is very important to reduce odors. Having fun with cars also means prioritizing safety—choosing the right brands can extend service intervals and be more cost-effective.
As a homemaker who drives my kids around every day, understanding the five oils, four filters, and three fluids is crucial. The five oils, like brake fluid, are directly related to braking safety, while power steering fluid makes the wheel easier to turn. Among the four filters, I pay special attention to the cabin air filter, which traps dust and protects my children's health. The three fluids include coolant to prevent overheating, windshield washer fluid for clear visibility, and battery fluid to maintain the starting system. I recommend doing a simple fluid level check every quarter—don’t wait for the warning light to come on. Regularly changing brake fluid can prevent accidents, and keeping windshield washer fluid stocked ensures clear vision in rain or snow. Taking good care of the car brings peace of mind, and teaching my husband to change filters himself saves trouble and even strengthens family harmony.
