Which Engine Oil to Choose for Buick Excelle?
2 Answers
Buick Excelle 1.4T originally uses Mobil 1 5W-30W full synthetic engine oil, while Buick Excelle 1.5L uses the original 5W-30W semi-synthetic engine oil with a filling capacity of approximately 3.7L. It is recommended to use the original engine oil provided by the manufacturer for Excelle. More information about automotive engine oil is as follows: 1. Compared between 5W30 and 0W20, their high and low-temperature performance are different. 0W20 has better low-temperature fluidity and can be used in lower environmental temperatures; while 5W30 has better high-temperature protection performance, with higher viscosity. Although it may increase fuel consumption, considering the Excelle model, 5W30 is more suitable for its engine requirements. 2. The engine oil grade 5W-30W is generally suitable for winter and summer use in China. For hotter regions, 5W-40W can be used. The summer oil grades are: 20W, 30W, 40W, 50W, 60W. The larger the number, the higher the viscosity and the higher the applicable maximum temperature.
When choosing engine oil, I always refer to the Buick Excelle owner's manual first. It typically recommends 5W-30 viscosity oil, where the numbers represent cold-temperature fluidity and high-temperature stability. The manual states that models after 2015 are suitable for full synthetic oil because it offers better lubrication, high-temperature resistance, and extends engine life. I use 5W-30 in northern winters and stick with the same grade in summer for consistency. Full synthetic oil is slightly more expensive but has a longer change interval, usually every 8,000-10,000 kilometers, making it cost-effective. I recommend choosing brands with API certification SN or SP grades, such as Mobil or Castrol, and avoiding unknown brands. Oil quality affects the entire driving experience—poor oil can cause louder engine noise and reduced fuel efficiency. Regularly checking oil levels and ensuring there are no leaks or degradation is crucial.
