When performing your maintenance on the 2022 CX-9, pay close attention to the fluid capacities. The engine requires a total of 5.1 quarts, including the filter replacement. After refilling, it is crucial to check the oil level to ensure it is within the optimal range. For the cooling system, the capacity is approximately 10.5 quarts. The 6-speed automatic transmission (GW6AX-EL) typically requires between 3.7 and 5.1 quarts for an initial fill, with a total capacity of 8.5 quarts if the torque converter is also filled. The transfer case and rear differential require smaller amounts, typically measured in pints, but using the correct viscosity is critical for smooth operation.
Engine Protection for Turbocharged Engines
The 2.5-liter SkyActiv-G engine in the CX-9 features a turbocharger, which subjects the engine oil to extreme thermal stress and shear forces. Standard conventional oils can break down quickly under these conditions, leading to carbon buildup on turbo seals and potential failure. AMSOIL Signature Series 5W-30 is tested specifically for these conditions, offering 72% better protection against turbocharger coking compared to industry standards. This protection ensures that your turbocharger spins freely and cools down efficiently after hard driving, extending the life of one of the most expensive components in the engine.
For owners with higher mileage, the engine’s internal tolerances may have shifted slightly over the years.

It also features enhanced anti-wear additives to help maintain oil pressure and seal conditioning agents to reduce oil consumption, making it an ideal choice for CX-9s that have traveled over 75,000 miles.
Filter selection is equally important as the oil itself. The AMSOIL Oil Filter is constructed with a synthetic blend media that provides 99% filtration efficiency at 20 microns. This level of filtration is critical because it removes the microscopic particles that cause wear on bearings, pistons, and camshafts. The filter also features a greater capacity for contaminants than many competing brands, meaning it can hold more dirt before becoming restricted, ensuring consistent oil flow throughout the extended service interval.
Transmission and Drivetrain Care
The 6-speed automatic transmission in the CX-9 is designed for efficiency, but it can suffer from heat-related degradation over time. Using a high-quality synthetic automatic transmission fluid like the AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid helps maintain the correct viscosity even under heavy towing or in stop-and-go traffic. This fluid remains fluid in sub-zero temperatures while providing a reserve of protection during heavy use, ensuring smooth shifts and preventing the sludge buildup that can cause transmission failure.
The drivetrain components, including the transfer case and rear differential, also benefit from synthetic lubrication. The 75W-85 100% Synthetic Gear Lube is formulated to control thermal runaway, a condition where the gear lube breaks down due to excessive heat generated during heavy load or off-road use. This gear lube contains friction modifiers specifically designed for limited-slip applications, reducing the likelihood of chattering or binding when turning. By maintaining proper lubrication in these areas, you ensure that power is delivered efficiently to the wheels and that the transfer case operates silently.
Complete Fluid Maintenance Strategy
A comprehensive maintenance plan involves more than just oil changes. The cooling system in the CX-9 plays a vital role in protecting the turbocharger and engine from overheating. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant provides protection against corrosion for all cooling system metals, gaskets, and hoses. Its poly-organic acid (OAT) formulation is phosphate- and nitrate-free, making it compatible with a wide variety of engine designs and ensuring long-term stability.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is another critical component that is often overlooked. Over time, brake fluid absorbs moisture from the air, which lowers its boiling point and can lead to brake fade or corrosion of brake lines and calipers. This synthetic brake fluid resists this moisture absorption, maintaining a stable viscosity over a wide temperature range. This ensures excellent ABS and traction-control responsiveness, giving you confidence in the braking system regardless of the weather conditions.
