Maintaining your 2016 Acura TLX with the K24W7 5 engine requires precise fluid specifications to ensure optimal performance and longevity. This 2.4-liter four-cylinder powertrain delivers smooth power and reliable fuel efficiency, but its longevity depends heavily on using the correct lubricants. The manufacturer specifies a viscosity of 0W-20 for all temperature conditions, with a total oil capacity of 4.2 quarts. When changing the oil filter, the capacity increases to 4.4 quarts, a critical detail for service technicians to note. Proper lubrication not only reduces internal friction but also helps manage heat, keep contaminants suspended, and protect critical components like the turbocharger and variable cylinder management system from wear.

Essential Engine Oil Specifications
The heart of your 2016 Acura TLX is the 2.4-liter K24W7 5 inline-four engine. This powerplant is known for its balance of power and efficiency, but it requires precise maintenance to maintain its reliability. The engine oil capacity is strictly 4.2 quarts during a standard change. However, when the oil filter is replaced, which is a standard part of any oil change service, the total fluid requirement rises to 4.4 quarts. It is vital to monitor the oil level after the refill and ensure it reaches the proper mark on the dipstick. The drain plug torque must be set to 30 ft/lbs to ensure a secure seal without damaging the threads.
AMSOIL offers a full range of 0W-20 synthetic motor oils designed to exceed the performance standards of this engine. The Signature Series stands out with up to 25,000 miles of protection, making it the premium choice for drivers who want to maximize the time between changes. It provides 75 percent more protection against horsepower loss and wear compared to conventional oils. For those seeking a balance between cost and extended service life, the Extended-Life formula offers 20,000 miles of protection and superior cleaning power to help maintain engine smoothness. The OE line provides a robust 100 percent synthetic option that fights sludge and deposits effectively, while the High-Mileage variant is specifically engineered for engines that have surpassed 75,000 miles, helping to reduce sludge by 67 percent and enhance cleaning power.
Filtration and Cooling System Care
Engine oil alone cannot provide complete protection; the filtration system plays a critical role in maintaining engine health. The AMSOIL Oil Filter is designed to capture wear-causing contaminants with a filtration efficiency of 99 percent at 20 microns. This helps reduce engine wear significantly compared to standard filters. For vehicle owners who prefer an alternative brand, the WIX Oil Filter is also a recommended option, offering premium media that outperforms many original equipment manufacturer-branded filters. Both filters are essential for trapping particles that can cause premature wear on the K24W7 engine.
Cooling system integrity is equally important for preventing overheating and corrosion. The 2016 Acura TLX requires a coolant capacity of 6.7 quarts. AMSOIL provides two excellent options for this requirement. The Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 formulation made from ethylene glycol, requiring no mixing and offering protection for up to 150,000 miles or five years. It is compatible with all other antifreeze colors and free from phosphates, nitrates, nitrites, silicates, borates, and amines, which can be damaging to seals and gaskets over time. Alternatively, the Propylene Glycol Antifreeze is a concentrated formula that must be mixed with distilled or high-quality water. This eco-friendly option allows for even longer service intervals, protecting the cooling system metals, gaskets, and hoses from erosion and corrosion.
Transmission and Brake System Fluids
The 2016 Acura TLX with the 2.4L engine is equipped with an 8-speed automatic transmission (MDSA….SL156). Proper fluid levels and quality are essential for the transmission’s operation. A total fill for this transmission requires 7.7 quarts, while an initial fill capacity is 4.3 quarts. Using the correct fluid prevents sludge buildup and protects against wear from heavy use. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is specifically designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid even in sub-zero temperatures and provides reserve protection during heavy use, ensuring the 8-speed transmission shifts smoothly and efficiently.
Safety is paramount when it comes to the braking system. The Acura TLX requires a specific brake fluid, often identified by the Acura Heavy Duty Brake Fluid DOT 3 specification. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement. It is formulated to provide excellent ABS and traction-control responsiveness, ensuring the vehicle stops reliably in all conditions. The synthetic formulation maintains a stable viscosity over a wide temperature range, preventing brake fade during heavy driving and ensuring consistent pedal feel. This fluid is compatible with the vehicle’s brake system requirements and offers a significant upgrade in performance compared to conventional fluids.
Additional Maintenance and Protection
Beyond the core mechanical fluids, there are several other products that can enhance the performance and longevity of your 2016 Acura TLX. For seasonal storage or long periods of inactivity, AMSOIL Engine Fogging Oil is highly effective. It protects internal engine components from rust and corrosion, making it ideal for storing the vehicle during winter months. Similarly, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup that can clog injectors and carburetors. This is particularly useful if the vehicle is used infrequently or stored for extended periods.
To maintain the vehicle’s appearance and protect its finish, a variety of detail products are available. AMSOIL Miracle Wash Waterless Wash and Wax Spray requires no water or soap, leaving the vehicle with a fantastic shine and a protective finish that repels dust. For those looking to enhance engine performance, the AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14 percent horsepower and clean fuel injectors to 100 percent flow rate. This additive is especially beneficial for engines with direct injection, helping to prevent carbon buildup and improve fuel economy.
For general vehicle maintenance, AMSOIL Synthetic Multi-Purpose Grease is excellent for chassis lubrication, offering outstanding low-temperature pumpability and resistance to thermal degradation. It also resists oxidation and shear, making it a long-lasting choice for heavy and abusive loads. If the vehicle requires protection against rust and corrosion, particularly from road salt or moisture, the AMSOIL Heavy-Duty Metal Protector provides a long-lasting, wax-like coating that shields steel, iron, aluminum, and other metal surfaces. For cleaning, the AMSOIL Heavy-Duty Degreaser quickly removes oil, tar, and grime from engine surfaces, while the AMSOIL Engine Degreaser offers a professional-strength formula for the toughest grease and dirt.
To keep the vehicle looking its best, AMSOIL Exterior Ceramic Spray offers easy application and rapid water shedding, protecting against UV rays. For interior care, the AMSOIL Interior Detailer is available in Light Lemon and Scent Free varieties, providing 90-day UV protection and trapping odors. For glass surfaces, the AMSOIL Glass Cleaner cuts through grease and grime effectively without leaving streaks. These products ensure that your Acura TLX remains not only mechanically sound but also visually appealing.
