Buick Excelle uses 5W30 or 0W30 engine oil. Engine oil is referred to as the lifeblood of the engine, serving not only a lubricating function but also roles in cleaning, sealing, cushioning, rust prevention, and heat dissipation. Without engine oil, the engine cannot operate properly. The Buick Excelle is equipped with a 1.3-liter naturally aspirated engine across all models, delivering a maximum horsepower of 107, a maximum power of 79 kilowatts, a maximum torque of 133 Newton-meters, and a top speed of 170 kilometers per hour. In terms of fuel consumption, according to the comprehensive fuel consumption data from the Ministry of Industry and Information Technology, the Excelle's fuel consumption is 4.6 liters per 100 kilometers.

I own a Buick Excelle, which I've driven for five or six years. I've changed the oil myself several times, always opting for 5W-30 synthetic oil—the most recommended grade suitable for most climates. It ensures easy cold starts in winter and provides excellent lubrication in summer heat, keeping the engine running smoothly. The Buick manual also specifies this grade. I've tried other oils, but noticed the engine noise increased and fuel consumption rose slightly. I recommend changing the oil every 5,000 kilometers or six months—don't delay too long. Although synthetic oil is more expensive, it offers better protection and extends engine life. I also add a bit of oil additive to help clean carbon deposits, giving me peace of mind on long trips. Don’t skimp on maintenance; using the wrong oil can turn minor issues into major repairs.

Using 5W-30 full synthetic oil is very suitable for the Buick Excelle, providing quick engine response, fuel efficiency, and durability. I prioritize performance—lower viscosity reduces noise, while higher viscosity may cause unstable oil pressure. Synthetic oil offers strong wear resistance, extending oil change intervals to over 8,000 kilometers, saving both money and hassle. It’s less affected by environmental temperatures and ensures smoother cold starts. Don’t forget to check the dipstick and perform regular maintenance. Choosing the wrong grade, such as 10W-40, may increase fuel consumption and cause long-term damage to piston rings. Stick to the manufacturer’s recommendations and avoid cheap, off-brand oils.

My car is a Buick Excelle. After buying it as a beginner, I consulted professional friends who advised sticking with 5W-30 engine oil. The manual provides clear and simple instructions. Synthetic oil protects the engine, resists freezing and overheating, and doesn't affect performance. Remember to check it during every maintenance service and don't exceed the time limit. Safety comes first, and good engine oil reduces the risk of malfunctions.
