What kind of oil does the Buick Envision use?
2 Answers
Buick Envision uses 5w30 oil. The functions of the oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear; 2. To bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; 3. To circulate carbon deposits, sludge, and worn metal particles on engine parts back to the oil tank, and flush away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. Taking the 2021 Buick Envision as an example, it belongs to the midsize SUV category, with body dimensions of: length 4694mm, width 1839mm, height 1686mm, wheelbase of 2750mm, fuel tank capacity of 66l, and curb weight of 1610kg.
I've been driving a Buick Envision for several years and found that it performs best with full synthetic oil. The specific viscosity depends on the model year. For my 2020 model, the manual recommends 0W-20, which makes the engine run smoother and more fuel-efficient. Choosing the right oil is crucial—using high-viscosity oil like 5W-40 can increase engine wear and fuel consumption. Always check the manual first to confirm the specification; older models like those before 2015 might use 5W-30, while newer ones typically use 0W-20. I usually go with Mobil 1 or Shell for oil brands, ensuring certifications like API SN for safety. Don't forget regular oil changes—every 8,000 to 10,000 kilometers—or degraded oil can cause strange noises or hard starts. Once, I delayed an oil change, and the engine noise increased, but it went back to normal after using proper oil. It's really not worth skimping on small things like this. Bottom line: follow the manual for peace of mind and hassle-free driving.
