Maintaining the lubrication system of your 2023 Acura MDX is essential for preserving the engine’s output and efficiency. The J35Y5 3.5-liter V-6 engine is a refined powerplant, but like all high-performance engines, it relies heavily on the quality of the motor oil circulating through it. AMSOIL Signature Series synthetic motor oils are designed to offer significantly more protection against horsepower loss and wear compared to conventional oils. Whether you are driving in extreme heat, freezing temperatures, or towing a heavy load, the engine oil must maintain its viscosity and lubricating properties without breaking down.
One of the most critical specifications for this vehicle is the oil grade. The 2023 MDX requires 0W-20 viscosity oil. The capacity for a full oil change, including the filter replacement, is 5.6 quarts. If you perform a top-off without changing the filter, the capacity is approximately 5.3 quarts. After refilling, it is important to check the oil level to ensure accuracy. The oil drain plug should be torqued to 30 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks.
For engine filtration, the AMSOIL Oil Filter is highly recommended for its efficiency. It allows for lower restriction while keeping engine parts properly lubricated and offers a greater capacity for contaminants than competing filters. A premium alternative is the WIX Oil Filter, which provides improvements over original equipment manufacturer filters. Both options ensure that harmful particles are removed from the oil, protecting vital engine components like bearings and camshafts.
Beyond the engine, the cooling system plays a vital role in the MDX’s durability. The cooling system capacity is 8 quarts. AMSOIL offers two primary cooling solutions: the Passenger Car & Light Truck Antifreeze & Coolant, which comes pre-mixed as a 50/50 solution and is compatible with all other antifreeze colors, and the concentrated Propylene Glycol Antifreeze. Both options provide protection up to 150,000 miles or five years. These coolants are free of phosphates, nitrates, and silicates, ensuring they do not damage the engine’s metals, gaskets, or hoses.
The 2023 Acura MDX features a sophisticated 10-speed automatic transmission. Proper lubrication here is key to smooth shifting and longevity. The fluid requirement varies slightly by drivetrain. For 2WD models, the total fill capacity is 8.8 quarts, with an initial fill of 4.5 quarts. For AWD models, the total fill capacity is 9.3 quarts, with an initial fill of 5.1 quarts. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is designed to withstand the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions. It provides reserve protection during heavy use, ensuring the transmission operates smoothly regardless of the driving environment.
For owners of the AWD variant, the transfer case also requires attention. The capacity for the transfer case is approximately 1.2 pints. AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is an excellent choice here. It controls thermal runaway, protects against rust and corrosion, and contains friction modifiers beneficial for limited-slip applications. This helps reduce operating temperatures and extends the life of seals and equipment.
Braking performance is another area where synthetic fluids offer distinct advantages. The Acura MDX requires a brake fluid meeting DOT 3 specifications (P/N 08798-9008A). The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems. It maintains stable viscosity over a wide temperature range, which is crucial for consistent braking performance in all weather conditions.
