The 2016 Lexus RX350 is powered by a 3.5-liter V6 engine, specifically the 2GR-FKS variant. This engine is renowned for its balance of smooth operation and reliable power. For optimal engine care, the correct oil viscosity is crucial. The manufacturer specifies 0W-20 motor oil for all temperatures, which is the best choice for achieving good fuel economy and ensuring quick engine starts during cold weather. When changing the oil, the total capacity for the engine is 5.7 quarts with the filter and 5.8 quarts with the filter, depending on the specific service procedure and check requirements. After refilling, it is essential to check the oil level to ensure it is correct. The torque specification for the oil drain plug is 30 ft/lbs, and owners should always install a new washer on the drain bolt to prevent leaks. For a complete kit, use AMSOIL OE 0W-20 100% Synthetic Motor Oil with a WIX Oil Filter.
The transmission in the 2016 RX350 is an automatic unit, identified by codes such as U881F for FWD and U881E for AWD models. Maintaining this transmission is vital for the vehicle’s shifting performance and longevity. The capacity for the automatic transmission varies by configuration. For the 8-speed FWD unit, the initial fill capacity is 3.2 quarts, while the total fill capacity is 7.2 quarts. Similarly, for the 8-speed AWD unit, the initial fill is 3.2 quarts with a total fill of 7.2 quarts. Using a fluid designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain helps protect the internal components from wear and sludge buildup. AMSOIL transmission fluids remain fluid in sub-zero temperatures and provide reserve protection during heavy use, ensuring the vehicle drives with confidence. Recommended options include AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid or AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid.
Beyond the engine and transmission, the 2016 Lexus RX350 utilizes specific lubricants for its transfer case and rear differential. The transfer case requires a lubricant compatible with Toyota Genuine Gear Oil LT specifications, with a capacity of 1.7 pints. The rear differential in AWD models also requires 75W-85 gear oil meeting GL-5 standards, with a capacity of 1.1 pints. The torque for the fill plug on the transfer case is 36 ft/lbs, and gaskets must be installed on both drain and fill plugs to ensure a proper seal. AMSOIL SEVERE GEAR 75W-85 is an excellent choice for these applications, as it controls thermal runaway, protects against rust and corrosion, and helps reduce operating temperatures, extending the life of the oil, seals, and equipment. Using a high-quality WIX Air Filter also supports overall engine health.
Braking systems also demand high-quality fluid. The recommended brake fluid for the 2016 Lexus RX350 is a hydraulic brake fluid meeting DOT 3 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed to provide excellent responsiveness for ABS and traction control systems. It maintains a stable viscosity over a wide temperature range, which is critical for safe braking performance in varying conditions. For owners who store their vehicles during the off-season, AMSOIL offers specialized stabilizers and fogging oils to protect internal engine components from corrosion and keep fuel fresh for up to 12 months. Consider using AMSOIL Gasoline Stabilizer and AMSOIL Engine Fogging Oil for seasonal storage protection.
