What is the oil specification used in the Buick Envision?
2 Answers
Buick Envision uses 5W30 full synthetic oil. Full synthetic oil offers superior quality, providing noticeable benefits in the following aspects: smoother cold starts, especially evident in northeastern regions; improved fuel efficiency; longer oil change intervals, equivalent to 1.5 times or more of conventional lubricants; extended engine lifespan and reduced maintenance frequency; and cleaner engine cylinders due to the excellent detergency of synthetic oil. The Buick Envision has body dimensions of 4694 mm in length, 1839 mm in width, and 1686 mm in height, with a wheelbase of 2750 mm. It features front-wheel drive, a front suspension type of MacPherson independent suspension, a rear suspension type of multi-link independent suspension, and a unibody structure.
I'm a veteran with 15 years of experience in auto repair shops, and I've worked on the Buick Envision many times. It requires 5W-30 full synthetic oil with the GM dexos1 certification label—no compromises. Using the wrong viscosity like 10W-40 or conventional mineral oil can lead to premature engine wear, increased fuel consumption, delayed cold starts in winter, and carbon buildup from overheating in summer. The owner's manual states it clearly: I recommend changing every 7,500 miles or six months, but it's best to check the dipstick monthly to ensure proper oil levels. For aggressive driving, oil quality becomes even more critical to protect the engine, extend its lifespan, and save money. If you frequently take long trips, this specification offers excellent stability, reducing breakdown risks and simplifying repairs.
