What Brand is the Original Buick Engine Oil?

[OAshley]

Buick's original engine oil is from the Mobil brand, specifically the Mobil 1 5W30 full synthetic oil. Here is more related information: 1. The oil needs to meet certification standards: Buick does not necessarily require the use of dexos-certified oil, and other brands of oil can also be used. However, the oil must meet certification standards, as certified oil provides a certain level of quality assurance. Different Buick models may use different oil types and brands, so owners should closely consider their vehicle model when choosing oil to better protect the engine and extend its service life. 2. Different oils have their own characteristics: Shell and Mobil oils each have their own features. Shell oil focuses on cleaning performance, while Mobil oil emphasizes long-lasting performance. If the vehicle's engine is turbocharged, it is recommended to use Shell oil. This is because turbocharged engines are prone to carbon buildup at high speeds, and using Shell oil can better clean the engine internals, creating a better working environment.
