Maintaining the optimal performance of your 2016 Buick Envision with the 2.0L turbocharged engine requires precision in every fluid change. This sophisticated powerplant, often found in General Motors’ luxury crossovers, operates under high thermal stress due to its direct injection and forced induction design. Selecting the correct synthetic lubricants ensures that the turbocharger bearings remain cooled, the combustion chamber stays free of carbon deposits, and the transmission shifts smoothly through all gears. Using the manufacturer’s specific viscosity and the correct filter element extends the service intervals while providing superior protection against wear, sludge, and oil consumption.

Engine Oil and Filtration Specifications
The 2.0L turbocharged engine in the 2016 Buick Envision demands a fluid that can handle significant thermal expansion and shear stress. The engine oil capacity is 6.0 quarts when including a filter change. It is crucial to check the oil level after refilling to ensure the correct volume is maintained. The drain plug torque specification is 18 ft/lbs. The factory specification has updated from Dexos 1 Gen 2 to GM Dexos 1 Gen 3, so using a synthetic oil that meets or exceeds these modern requirements is vital for turbocharger health.
The Signature Series 5W-30 is highlighted for its ability to provide 75% more engine protection against horsepower loss and wear. It is specifically tested to protect turbochargers better than the required GM specification. For owners prioritizing cleaning power to prevent carbon buildup in direct injection engines, the Extended-Life 5W-30 offers superior cleaning capabilities. If the vehicle has accumulated high mileage, the High-Mileage Motor Oil contains enhanced anti-wear additives and a boosted detergent package to reduce sludge by a significant margin.
Filtration is equally critical. The standard recommendation is the AMSOIL Oil Filter, which allows for lower restriction to keep engine parts lubricated. It also offers greater capacity for small, wear-causing contaminants. Alternatively, the WIX Oil Filter is available and provides premium media improvements over standard OEM-branded filters, ensuring that the oil circulating through the 2.0L engine remains clean.
Cooling System Requirements
Proper cooling is essential for the longevity of the turbocharged engine. The cooling system capacity for the 2016 Buick Envision is 8.1 quarts. A high-quality antifreeze formulation is necessary to prevent corrosion and erosion within the cooling passages. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that is phosphate-, nitrate-, nitrite-, silicate-, and amine-free. It is designed to exceed original equipment manufacturer requirements and protects all cooling system metals, gaskets, and hoses for up to 150,000 miles. For those who prefer a concentrated fluid that can be mixed with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a concentrated formula with a very high boiling point and excellent corrosion protection.
Transmission and Differential Fluids
The 2016 Buick Envision is equipped with a 6-speed automatic transmission (6T50). The total fill capacity is 9 quarts, while the initial fill capacity is approximately 4.2 quarts. The exact fluid amount varies based on the specific level check procedure, falling between 4.0 and 6.0 liters. Maintaining the transmission fluid is key to ensuring smooth shifts and protecting against wear, especially under heavy towing or hot driving conditions. The Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand the rigors of heavy use and remains fluid in sub-zero temperatures. It also provides reserve protection during heavy use and abuse. The AMSOIL OE Fuel-Efficient Automatic Transmission Fluid is another excellent option that protects against wear and aligns with fuel efficiency standards.
The rear differential requires attention as well. For the rear differential with a GLS25 specification, the capacity is 1.6 pints. For differential clutch applications (PS006), the capacity is 0.8 pints. The clutch fluid is serviced separately from the differential fluid. The AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is the recommended choice. It contains friction modifiers for limited-slip applications and helps control thermal runaway while reducing operating temperatures. This synthetic lube also provides long oil and seal life.
Other Fluids and Additives
Brake fluid is another critical area for safety and performance. The recommended specification is DOT 4 hydraulic brake fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides a stable viscosity over a wide temperature range, ensuring excellent ABS and traction-control responsiveness. It prevents the absorption of moisture which can lead to corrosion and boiling points that are too low for heavy braking.
Power steering fluid is also supported. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid reduces friction and helps seals remain soft to prevent leaks. It resists heat for a long fluid life and offers strong anti-wear protection. For fuel system maintenance, the AMSOIL P.i.® Performance Improver Gasoline Additive is highly effective. It restores GDI fuel injectors to 100% flow rate after just one tank of fuel, restoring up to 14% horsepower and improving fuel economy.
