What type of oil should be used for the Excelle?
1 Answers
The Buick Excelle is recommended to use fully synthetic oil. The method for selecting engine oil is as follows: 1. The selection of engine oil is quite particular and should be based on the highest and lowest temperatures in the local area, the vehicle's grade, and its condition. 2. If an oil with excessive viscosity is selected, it will increase the movement resistance and affect the engine's power. 3. If an oil with insufficient viscosity is selected, it cannot guarantee the lubrication quality and will exacerbate engine wear. 4. For engines that have already experienced significant wear and have larger component clearances, a higher viscosity grade oil can be selected to enhance the sealing performance of the components.
