The 2023 Chevrolet Traverse equipped with the 3.6L V-6 engine (Engine Code LFY) is a robust family hauler designed for versatility and comfort. However, to maintain its reliability and performance over thousands of miles, the vehicle requires precise lubrication. This engine operates under significant thermal stress and often experiences stop-and-go traffic conditions, making the quality of the oil and other essential fluids critical. Using the correct viscosity and type of lubricant ensures that moving parts are protected from wear, that engine cleanliness is maintained, and that the vehicle’s fuel economy remains optimal. Neglecting these fluid specifications can lead to sludge buildup, reduced power, and potentially costly repairs.

Engine Oil and Filtration Specifications
The 3.6L V-6 engine in the 2023 Traverse is a direct-injection, turbocharged-capable powerplant that demands high-quality lubrication. The manufacturer specifies a 5W-30 viscosity grade for all temperature conditions, with a total capacity of 6.0 quarts when changing the filter. It is crucial to refill the oil to the specified level and check the oil level after the refill. When draining the oil, the drain plug must be torqued to 18 ft/lbs, and the seal should be replaced to prevent leaks.
Choosing the right oil is not merely about filling a capacity; it is about choosing the right chemical architecture for your driving habits. The Signature Series 5W-30 is the ultimate choice for those who prioritize maximum engine protection. It contains a proprietary blend of synthetic base stocks and additives that significantly reduce wear and horsepower loss. For drivers who want to extend their service intervals without sacrificing protection, the Extended-Life 5W-30 is an outstanding alternative, offering enhanced cleaning power to remove deposits and prevent LSPI, a common issue in modern direct-injection engines.
Equally important is the filtration system. The oil travels through the filter constantly, removing microscopic metal shavings, soot, and sludge. The AMSOIL Oil Filter is engineered with premium synthetic media that allows for lower restriction while capturing contaminants more effectively than traditional paper filters. For those who prefer a high-performance aftermarket option, the WIX XP Oil Filter offers premium media that surpasses original equipment standards. Even the standard WIX Oil Filter is a reliable choice for routine maintenance.
Transmission and Drivetrain Fluids
The 2023 Traverse comes equipped with a 9-speed automatic transmission (model 9T65). This complex gearbox operates under significant heat and pressure, especially when the vehicle is used for towing or hauling cargo. The total fill capacity for the 9T65 transmission is 10 quarts, with an initial fill capacity of 5.3 quarts. The actual capacity typically falls between 5.0 and 6.0 liters for a standard drain and refill.
To keep this transmission shifting smoothly and to extend its service life, synthetic fluid is a necessity. Conventional fluids can break down under the extreme thermal stress of a 9-speed gearbox, leading to shudder and wear. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is formulated to handle these demanding conditions. It resists oxidation and shear stability loss, ensuring consistent performance over long intervals. For owners seeking a fuel-efficient fluid that offers OE-level protection, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is an excellent choice, providing wear protection and fluid stability.
The rear differential also requires specialized attention. Depending on the configuration, the vehicle may use a specific gear lubricant. The capacity for the rear differential varies by model, with some requiring 1.7 pints and others (for limited-slip applications) requiring only 0.8 pints. Using the correct viscosity is vital for the longevity of the gears and bearings. AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube provides advanced protection against thermal runaway and rust. It contains friction modifiers specifically designed for limited-slip differentials, ensuring smooth operation and reduced wear.
Cooling and Brake Systems
Maintaining the correct cooling system fluid is essential for the 3.6L engine’s thermal management. The total cooling system capacity is approximately 15.4 to 15.5 quarts, depending on the specific radiator configuration. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix that is phosphate-, nitrate-, and silicate-free. This OAT formulation ensures compatibility with all other coolant colors 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 to specific ratios, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers superior protection and environmental benefits. It provides protection up to 150,000 miles or 5 years, with significantly enhanced corrosion and erosion protection.
Braking performance is critical for safety, especially in a vehicle of this size. The Traverse relies on a hydraulic brake system that requires fluid with a high boiling point to prevent fade during heavy use. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets and exceeds DOT 3 and DOT 4 specifications. It maintains a stable viscosity over a wide temperature range, ensuring excellent responsiveness for ABS and traction control systems.
Additionally, the power steering system benefits from synthetic lubrication. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is designed to keep seals soft and prevent leaks while providing excellent high-temperature protection and low-temperature performance for quiet operation.
