The 2016 Acura RLX with the 3.5-liter V6 engine (Engine Code JNB1 1) is a sophisticated luxury sedan that demands high-performance lubricants to maintain its reliability and driving dynamics. Whether you are navigating city streets or cruising on the highway, using the correct viscosity and type of fluid is essential for reducing engine wear, optimizing fuel economy, and ensuring long-term durability. This guide details the specific AMSOIL products recommended for every lubrication point on your vehicle, from the crankcase to the brake system, ensuring your Acura receives the same level of protection it was engineered for.
Recommended AMSOIL Products
For the engine, a 0W-20 viscosity is required to meet the strict tolerances of the JNB1 1 engine. You have several premium options depending on your driving habits and mileage. The AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil offers the ultimate protection, allowing for extended drain intervals of up to 25,000 miles or one year while providing 75% more protection against horsepower loss and wear compared to conventional oils. For those prioritizing fuel efficiency and hybrid-style operation characteristics, the AMSOIL 0W-20 100% Synthetic Hybrid Motor Oil is an excellent choice, designed to maximize fuel economy and provide superior sludge control. If you need a balanced option with excellent value, the AMSOIL OE 0W-20 100% Synthetic Motor Oil fights sludge and deposits effectively. For vehicles with over 75,000 miles, the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil uses unique chemistry to boost detergent activity and reduce sludge. Finally, the AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil provides a robust middle ground with up to 20,000 miles of protection.
When it comes to filtration, pairing your oil with a high-quality filter is just as critical as the oil itself. The AMSOIL Oil Filter is engineered to filter 99 percent of contaminants at 20 microns, significantly reducing engine wear and extending the life of your components. Alternatively, the WIX Oil Filter offers premium media with improvements over standard OEM-branded filters, providing reliable protection for your Acura.
Transmission and Differential Lubrication
The automatic transmission in your 2016 Acura RLX is a complex 7-speed unit that operates under significant thermal stress. Using a fluid that maintains viscosity and resists oxidation is vital for smooth shifting and longevity. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is highly recommended. It withstands the rigors of heavy towing and elevated temperatures, remaining fluid even in sub-zero conditions. For a more budget-friendly option that still delivers exceptional fuel economy, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid protects against wear and ensures reliable performance. Note that the capacity varies by condition, with a total fill of approximately 4.8 quarts for a full service on the 7-speed unit.
While the transmission receives specific attention, the Acura RLX also features a Twin Motor Unit in the rear that requires specialized lubrication. The differential section recommends using the same high-performance synthetic automatic transmission fluid, specifically the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid or the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid, to lubricate the rear motor unit. This dual-use capability simplifies maintenance while ensuring the complex motor system is adequately protected against friction and heat.
Cooling, Braking, and Additives
Maintaining the correct temperature is crucial for the longevity of any internal combustion engine. The cooling system for the engine requires a substantial amount of fluid, with a capacity of 8.3 quarts, while the inverter system requires 1.3 quarts. For maximum cooling efficiency and corrosion protection, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ideal choice. This unique poly-organic acid formulation protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years. If you prefer a concentrated solution that you mix with water yourself, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers similar protection and can last even longer in heavy-duty applications.
Braking performance is non-negotiable for safety. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed for this vehicle to provide excellent ABS and traction-control responsiveness. It maintains stable viscosity across a wide temperature range, ensuring the brake system performs consistently in both extreme heat and cold. Additionally, for vehicle owners looking to improve fuel economy and clean the engine, the AMSOIL P.i.® Performance Improver Gasoline Additive is a powerful tool. It restores up to 14% horsepower and cleans GDI fuel injectors, helping prevent carbon buildup and ensuring the engine runs as efficiently as possible.
Seasonal Storage and Maintenance
When the vehicle is not in use for extended periods, proper storage procedures are necessary to prevent engine damage. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. To protect internal engine components from rust and corrosion during storage, the AMSOIL Engine Fogging Oil can be used to coat internal surfaces, ensuring the engine is ready to start when the season returns.
