Ensuring your 2016 Acura TLX with the 3.5L J35Y6 8 engine receives the proper lubrication is essential for maintaining its performance, fuel economy, and long-term durability. This sophisticated Honda-engineered powerplant is designed to operate with low-viscosity fluids, specifically 0W-20 motor oil, to minimize internal friction and maximize efficiency. Selecting the correct synthetic lubricants not only protects critical components from wear but also helps the vehicle withstand extreme operating temperatures, whether you are navigating stop-and-go city traffic or embarking on long highway drives.

For the 3.5-liter V6 engine found in your Acura TLX, the manufacturer specifies a 0W-20 viscosity grade. This low-viscosity fluid is critical for the engine’s variable cylinder management system and overall fuel efficiency. When performing an oil change, the total capacity, including the filter, is approximately 4.5 quarts. If you are topping off the oil after a minor leak or after an oil change where the filter was not replaced, the refill amount without a filter is closer to 4.2 quarts. Always verify the oil level on the dipstick after refilling to ensure the correct quantity is in the crankcase. The drain plug torque specification is 30 ft/lbs, ensuring a secure seal without damaging the threads.
AMSOIL offers four distinct motor oil formulations for this vehicle, each tailored to specific driver needs. The Signature Series 0W-20 is the premier choice for drivers seeking the longest possible service intervals and maximum protection. It is tested to provide 75% more engine protection against horsepower loss and wear compared to standard oils. For those who prefer a balance between performance and value, the Extended-Life 0W-20 offers 20,000 miles of protection and features 37% more cleaning power to remove deposits and keep the engine running smoothly.
Drivers looking for an entry-level synthetic option that still outperforms conventional motor oils will find the AMSOIL OE 0W-20 ideal. This oil is trusted by professional engine builders and effectively fights sludge and deposits. For older vehicles with over 75,000 miles, the 0W-20 High-Mileage Motor Oil includes a unique chemistry with boosted detergents and enhanced anti-wear additives to help engines last longer. These high-mileage oils are guaranteed for 12,000 miles or one year under normal service conditions.
Choosing the right filter is just as important as the oil itself. The AMSOIL Oil Filter allows for lower restriction, keeping engine parts better lubricated and providing greater capacity for small, wear-causing contaminants. It offers extended service life to match the synthetic oil. If you prefer a well-known aftermarket brand, the WIX Oil Filter is a solid alternative that offers improvements over OEM filters with premium media.
Transmission and Differential Care
The automatic transmission in the 2016 Acura TLX requires specific fluid to maintain smooth shifting and prevent wear. The vehicle is equipped with either a 9-speed automatic transmission (Q5L9 or Q5J4), and the total fill capacity varies. For the Q5L9, the total fill is 7.6 quarts, while the initial fill is 3.5 quarts. The Q5J4 requires a total of 6.6 quarts for a full fill, with an initial capacity of 3.5 quarts. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use.
For the transfer case and rear differential, AMSOIL recommends the SEVERE GEAR® 75W-90 100% Synthetic Gear Lube. This lubricant is designed to control thermal runaway and protect against rust and corrosion, helping to reduce operating temperatures. It contains friction modifiers for limited-slip applications and offers a long oil, seal, and equipment life. The transfer case holds 0.8 pints and requires a torque of 32 ft/lbs on the drain and fill plugs. The rear differential holds 3.8 pints. Always install a new gasket on the drain and fill plugs when servicing these components.
Cooling, Braking, and Additional Protection
Maintaining the cooling system is vital for the longevity of the V6 engine. The coolant capacity for the 2016 TLX is 8.9 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 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 radiator types. For a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a 150,000-mile protection interval and greatly surpasses standards for metallic corrosion and erosion.
Braking performance is non-negotiable for safety. The Acura TLX uses a DOT 3 fluid, and the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems. It maintains a stable viscosity over a wide temperature range, ensuring consistent pedal feel in both hot and cold weather.
For vehicle maintenance beyond lubrication, AMSOIL offers a range of care products. The AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, protecting against varnish and gum buildup, which is ideal for seasonal storage. The AMSOIL Engine Fogging Oil protects internal components during storage. For active vehicle care, the AMSOIL P.i.® Performance Improver can restore up to 14% horsepower and clean fuel injectors. For exterior maintenance, the AMSOIL Miracle Wash offers a waterless wash and wax solution, while the AMSOIL Exterior Ceramic Spray provides rapid water shedding and UV protection. For interior cleaning, the AMSOIL Interior Detailer (Light Lemon or Scent Free) traps odors and offers 90-day UV protection. Finally, for deep cleaning, the AMSOIL Brake and Parts Cleaner removes contaminants without leaving residue.
