The Chevrolet Cavalier has a maintenance interval of 10,000 kilometers, with the first maintenance for a new car at 5,000 kilometers. Below are the detailed maintenance guidelines for the Cavalier: 1. After driving 20,000 kilometers, a major maintenance is required (including oil and oil filter replacement, air filter, cabin air filter, and fuel filter replacement). For minor maintenance (oil and oil filter replacement), it is recommended to replace the air filter and cabin air filter annually. If frequently driving in dusty or sandy areas (e.g., construction sites), shorten the replacement interval. In humid environments, the air filter is more prone to bacterial growth in the cabin air filter. The cabin air filter directly affects the cleanliness of the air inside the vehicle and can filter out most dust. Replacing it can enhance engine power, reduce fuel consumption, and improve combustion efficiency. 2. Break-in period precautions: Avoid prolonged use of a single gear while driving. It is advisable to switch gears and distribute speeds appropriately to ensure even wear across all gears. Avoid excessively high speeds and RPMs; driving between 40-80 km/h with RPMs between 2,000-4,000 is ideal. Do not overload the vehicle, as excessive weight, sudden acceleration, or deceleration increases engine strain and places significant stress on the transmission components.

I've been driving my Chevrolet Cavalier for four years now. As an owner, I generally follow the maintenance schedule in the manual. The basic recommendation is to service it every 5,000 to 7,500 miles or six months, like changing the engine oil and filter – this needs to be done more frequently in congested city driving or short trips. If you do a lot of highway driving or the road conditions are good, you can stretch the interval to the upper limit. I also regularly check tire pressure, brake pads, and lights – these small things prevent big problems. The manual is the ultimate guide, don't just listen to others. Don't forget to replace the cabin air filter too; poor urban air quality affects health, and small maintenance can save big repair costs. In short, develop good habits, and your car will run more smoothly.

I recommend adjusting the maintenance interval flexibly based on your driving habits. The manual suggests every 5,000 to 7,500 miles or every six months, but since I frequently drive on highways, I can stretch it to 7,000 miles before servicing. The key is changing the oil and filter to prevent engine carbon buildup or sludge, which affects performance and fuel efficiency. Simple checks like tire pressure and windshield washer fluid can be done yourself—addressing minor issues early saves money and hassle. In harsh conditions like dusty roads or extreme weather, I shorten the interval to 5,000 miles to prioritize safety. Overall, don’t delay too long—keeping your car well-maintained extends its lifespan and avoids the hassle of premature replacements.

I stick to a simple principle when it comes to maintenance: follow the manual's recommendation of every 7,500 miles or six months as the baseline. The main focus is changing the engine oil to protect the engine and prevent overheating or wear. Whichever comes first, time or mileage, should be followed to avoid degraded oil affecting driving performance. Other checks like brakes and tires are also crucial to ensure safe and reliable driving. Regular maintenance extends the car's lifespan and reduces breakdowns.
