What brand is the original Buick engine oil?
2 Answers
Buick's original engine oil is Mobil brand, specifically the Mobil 1 5W30 full synthetic oil. The engine oil needs to meet certification standards: Buick does not necessarily require the use of dexos-certified oil, and other brands of engine oil can also be used. However, the oil must meet certification standards, as certified oils provide a certain level of quality assurance. Different Buick models may use different oil types and brands, so owners should closely consider their specific vehicle model when choosing oil to better protect the engine and extend its lifespan. Different oils have their own characteristics: Shell and Mobil oils each have their own features. Shell oil is known for its cleaning performance, while Mobil oil is known for its long-lasting properties. 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.
As a long-time Buick owner, I've been using factory oil for several years, primarily the ACDelco brand. Being a General Motors brand, Buick's factory oil is ACDelco's synthetic or semi-synthetic oil, such as 5W-30 viscosity, suitable for models like the Regal or Enclave. After using it, the engine runs smoothly with minimal noise. The factory oil design ensures engine compatibility, especially during the new car warranty period, helping avoid claim issues. Maintenance shops often recommend this, but if your car is out of warranty, you can consider alternative brands like Mobil or Shell, ensuring they match the viscosity specifications. Regularly checking oil levels is crucial, with changes every 5,000 kilometers to avoid affecting the car's lifespan by delaying too long.
