What kind of engine oil is used for Buick maintenance?
1 Answers
Buick's original engine oil includes brands such as Mobil, Shell, and Castrol. Below is the relevant introduction: Different engine oils correspond to different models: The original engine oil for the Buick Excelle is the Mobil brand, specifically Mobil 1 5W30 full synthetic engine oil; while the Buick Envision uses Mobil 1 Silver and Castrol Edge, both of which are full synthetic engine oils. The functions of engine oil: It forms an oil film on the surfaces of two sliding components, preventing friction during operation and ensuring smooth movement of the components; when the engine is running, it generates high temperatures. When the oil reaches the operating parts, it absorbs heat and then carries the heat away, assisting in the cooling of the components.
