What is the oil specification for the Envision?
4 Answers
The oil specification for the Envision is 5W30 fully synthetic oil, and approximately 5.4L is required during maintenance. According to the Buick Envision's maintenance manual, maintenance is required every 5,000 kilometers. The Envision models currently on sale are the 2019 models, divided into National V and National VI versions. The Envision has dimensions of 4686mm in length, 1839mm in width, and 1660mm in height, with a wheelbase of 2750mm. The Envision is available in both two-wheel drive and four-wheel drive versions, featuring a front-engine four-wheel-drive layout with an on-demand four-wheel-drive system. The front and rear brake types are ventilated disc and disc, respectively, with an electronic parking brake.
My Envision is the 2019 2.0T model, and the manual clearly states that it requires 5W-30 full synthetic oil with the dexos1 certification mark. Last time during maintenance at the 4S店, the technician specifically reminded me that for China VI emission standard models, it's better to choose SP-grade oil, which is more friendly to the particulate filter. Actually, the main difference between 0W-20 and 5W-30 lies in low-temperature fluidity; using 0W-grade oil in northern winters does make for quicker starts. However, for older naturally aspirated engines, 5W-30 is still the safer choice, as oil that's too thin might actually increase wear. I recommend keeping an eye on the technician during each maintenance to check for the dexos1 certification mark on the oil container—only oil with this mark guarantees quality. Don't let roadside shops fool you with off-brand oil; after all, this car can be quite picky.
Just had my 2021 Enclave Plus serviced, and the official requirement is to use 0W-20 full synthetic oil. The 4S shop uses Silver Mobil, and you can see the green dexos1 Gen2 certification on the barrel. The maintenance supervisor said that China VI-B models must use low-ash oil, otherwise the exhaust pipe is prone to clogging. Here's a cool tip: if the oil cap is stamped with 0W-20, never use 5W-30. New cars now use precision hydraulic control valves, and using the wrong viscosity will trigger a fault code. A fellow car owner once tried to save money by using the wrong oil, and their fuel consumption shot up by 2 points—the savings weren't enough to cover the extra fuel costs.
As a veteran mechanic with 10 years of experience repairing Buicks, the engine oil for Envision varies by year. Models before 2020 use 5W-30, while post-2020 models switch to 0W-20 – always look for dexos1 certification. Vehicles equipped with particulate filters must use SP-grade oil, otherwise the subsequent repair costs could buy ten barrels of oil. Our shop has encountered cases where incorrect oil caused variable cylinder system seizure, requiring an 8,000+ RMB overhaul. For routine maintenance, change oil every 8,000 km, or preferably at 7,000 km for frequent short-distance driving. Engine oil viscosity is like choosing clothes for your engine – the perfect fit matters most.
