The maintenance interval for the Excelle is determined by mileage, with an oil change and oil filter replacement required every 5,000 kilometers. The spark plug replacement intervals differ between the 1.4T and 1.5L models: every 40,000 kilometers for the 1.4T model and every 30,000 kilometers for the 1.5L model. The air filter, cabin air filter, and fuel filter should be replaced every 20,000 kilometers, while the brake fluid needs replacement every 30,000 kilometers. The Excelle's body dimensions are 4609mm in length, 1798mm in width, and 1486mm in height, with a wheelbase of 2640mm, making it a standard compact car.

My Excelle has been maintained every 5,000 kilometers or six months since I picked it up, whichever comes first. Last time, I only drove 3,000 kilometers in six months but still went to change the engine oil and oil filter. The mechanic at the shop said the oil would deteriorate over time. The manual states that a more extensive maintenance is required at 20,000 kilometers, including replacing the air filter and brake fluid. I specifically asked the mechanic to take comparison photos of the old and new parts and share them in the group—the filter was as dirty as a rag. Maintenance really shouldn’t be delayed. Once, my neighbor’s Excelle went over by 2,000 kilometers before servicing, and the engine ended up sounding like a tractor, costing an extra 1,000+ yuan to fix. Now, I set phone reminders and book a service slot at the 4S shop as soon as it’s time.

Commuting with the Buick Excelle is particularly hassle-free, just remember the maintenance interval is every 5,000 kilometers or six months. For the first service, I drove exactly 5,000 km and the 4S dealership directly replaced it with genuine engine oil and filter. Later, with more experience, I bought the cabin air filter online and replaced it myself, saving 200 yuan in labor costs. Spark plugs don't need frequent changes—the mechanic said to check them at 40,000 km. I remember before a long trip to Yunnan last year, I made sure to service the car in advance, and it performed exceptionally steady on the mountain roads. Actually, the car's infotainment system has a maintenance reminder feature, but I prefer jotting it down in a notebook, recording the mileage every time I refuel.

When I first bought the car, I carefully studied the Buick Excelle maintenance manual, which clearly stated service intervals of every 5,000 kilometers or six months. The free first service taught me the rules - engine oil and filters must be changed on schedule, otherwise it affects engine lifespan. Tire rotation needs to be done every 8,000 kilometers, otherwise like in my case, the front tires wore noticeably faster than the rear ones. Before rainy seasons, I always check vulnerable components like wipers and lights, these don't need to wait for regular maintenance cycles. Once after a summer rainstorm, the headlights fogged up due to aging seals, which I repaired before the scheduled maintenance.
