Maintaining the 2012 Chevrolet Traverse with a 3.6L V6 engine requires more than just filling up the gas tank; it demands precise lubrication protocols to ensure longevity and performance. This crossover SUV relies on specific fluid types to manage the thermal stresses of its aluminum block, the friction demands of its 6-speed automatic transmission, and the cooling needs of its complex cooling system. Using the wrong oil grade or viscosity can lead to reduced fuel economy, increased engine wear, and premature transmission failure. AMSOIL synthetic lubricants are engineered to exceed the rigorous specifications set by General Motors, providing a superior barrier against wear, sludge, and oxidation under both everyday driving conditions and severe duty scenarios like towing or hauling heavy loads.

The engine of your 2012 Chevrolet Traverse is the heart of the vehicle, and it requires specific care to maintain peak efficiency. The 3.6L V6 engine, identified by code [D] LLT, demands 6 quarts of motor oil when performing a standard change including the filter replacement. It is critical to follow the updated GM Dexos 1 Gen 3 specification rather than older standards to ensure compatibility with modern engine protection requirements. The oil drain plug should be torqued to 18 ft-lbs to prevent leaks or thread damage. For those seeking the ultimate in engine performance, the Signature Series offers unmatched protection against horsepower loss, while the High-Mileage formula addresses the unique needs of older engines with increased wear, reduced sludge, and better oil consumption control. Choosing the right oil viscosity, typically 5W-30 for all temperatures, ensures the engine starts easily in cold weather while maintaining proper film strength at high operating temperatures.
Beyond the engine, the transmission is a critical component that often suffers from neglect. The 2012 Traverse utilizes a 6-speed 6T75 automatic transmission, which benefits significantly from AMSOIL‘s specialized synthetic transmission fluids. While a simple drain and fill requires approximately 4.2 quarts, a total fill for a fresh service requires 9.5 quarts to ensure the valve body and torque converter are properly filled. The fluid must remain stable under the heat generated by heavy towing or stop-and-go traffic. AMSOIL’s OE Fuel-Efficient and Signature Series transmission fluids are designed to protect against wear, sludge, and the temperature extremes that can lead to transmission failure. Using these fluids helps maintain smooth shifting and extends the service life of the transmission system.
Drivetrain and Cooling System Maintenance
The drivetrain of the Traverse, including the transfer case and rear differential, operates under substantial stress, particularly for owners who utilize the vehicle for off-road activities or towing. The GETRAG 790 transfer case and the SL136 rear differential both require 2.1 pints of lubricant. The fill and drain plugs for the transfer case must be torqued to 29 ft-lbs to ensure a secure seal. AMSOIL SEVERE GEAR® 75W-90 Synthetic Gear Lube is the recommended solution for these components. This fluid is formulated to control thermal runaway, a common issue where friction heats the fluid, reducing its viscosity and causing further wear. It also protects against rust and corrosion while helping to reduce operating temperatures, which is vital for extending the life of the gears and bearings.
Temperature regulation is another pillar of vehicle longevity. The 2012 Chevrolet Traverse requires 11.4 quarts of coolant to fill the cooling system completely. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol, 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it safe for all engine metals and compatible with various antifreeze colors. For those who prefer a concentrated option that can be mixed with distilled water, the Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles in passenger cars and light trucks, or even longer in heavy-duty applications. Both options exceed OEM requirements for metallic corrosion and erosion protection.
Brake, Fuel, and Fluid System Care
Safety and performance are paramount when it comes to the braking system. The 2012 Traverse utilizes a hydraulic brake fluid system requiring DOT 3 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed to provide excellent ABS and traction-control responsiveness. Unlike conventional fluids that can absorb moisture and boil under heavy braking, the synthetic formula maintains a stable viscosity over a wide temperature range, ensuring consistent pedal feel and stopping power. Additionally, the power steering system, which on this model utilizes fluid compatible with DEXRON-VI Automatic Transmission Fluid, can be serviced using the same high-quality transmission fluid to ensure smooth operation and protection against wear.
For owners concerned with fuel economy and engine cleanliness, the AMSOIL P.i.® Performance Improver gasoline additive is a powerful tool. This additive restores up to 14% horsepower and cleans GDI fuel injectors back to 100% flow rate after just one tank of fuel. It helps prevent carbon buildup, controls pre-ignition knock, and reduces the need for higher-octane fuel. The AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor further protects the fuel system and upper cylinders, compatible with capless fuel systems. Whether for daily driving or extended storage, these additives ensure the fuel system remains clean and efficient, maximizing the performance of the 3.6L engine.
