Engine Oil Selection and Specifications
The heart of your 2016 Toyota Sequoia is the 5.7L V8 engine, identified by the code 3UR-FBE 5 Flex. This powerhouse engine operates under significant load, whether you are navigating city traffic or towing a trailer on the highway. To ensure the internal components—pistons, rings, bearings, and camshafts—are adequately protected, AMSOIL recommends a viscosity of 0W-20 for all operating temperatures. This specific grade is optimal for balancing fuel economy and engine starting performance in cold weather while providing sufficient film strength at high operating temperatures.
The total capacity for the engine, when changing the oil filter simultaneously, is 7.9 quarts. It is critical to refill with this exact amount and check the oil level after the refill to ensure proper lubrication without overfilling. The torque specification for the oil drain plug is 30 ft/lbs, and it is mandatory to install a new washer on the drain bolt each time you perform a service. For owners operating their Sequoias on E85 or M85 fuels, it is important to note that extended oil drains should only be extended through the use of oil analysis, as these fuels can impact oil stability.
For those seeking the absolute best in protection, the AMSOIL Signature Series 0W-20 offers 75% more engine protection against horsepower loss and wear. It is guaranteed for up to 25,000 miles or one year. If you prefer a slightly lower price point without sacrificing synthetic benefits, the AMSOIL Extended-Life 0W-20 provides up to 20,000 miles of protection and features enhanced cleaning power. For high-mileage vehicles exceeding 75,000 miles, the AMSOIL High-Mileage 0W-20 uses a unique chemistry to reduce sludge by 67% and helps engines last longer.
Pairing your motor oil with the correct filter is just as important as the oil itself. The AMSOIL Oil Filter is engineered to allow lower restriction, keeping engine parts lubricated, and offers a greater capacity for small, wear-causing contaminants. It achieves filtering efficiency of 99 percent at 20 microns. Alternatively, the WIX Oil Filter serves as a high-quality OEM alternative with premium media that outperforms standard manufacturer-branded filters.
Transmission and Differential Lubricants
The automatic transmission in the 2016 Toyota Sequoia is a critical component for smooth power delivery. Using a fluid designed to withstand heavy towing, elevated temperatures, and challenging terrain is essential for maintaining shift quality and preventing sludge formation. The transmission fluid capacity for the 6-speed AB60F model is a total fill of 11.7 quarts, with an initial fill of 2.2 quarts. The AMSOIL Signature Series Fuel-Efficient ATF is highly recommended for its ability to withstand the rigors of heavy use and maintain fluidity in sub-zero temperatures. For a value-oriented option, the AMSOIL OE Fuel-Efficient ATF provides reliable protection against wear.
For the transfer case and differentials, AMSOIL recommends the SEVERE GEAR® line, which is designed for extreme pressure and heavy-load applications. The transfer case requires a GL-5 lubricant, and the AMSOIL SEVERE GEAR® 75W-90 is an excellent choice. It contains friction modifiers for limited-slip applications and helps control thermal runaway. The front and rear differentials specifically require 75W-85 viscosity. The AMSOIL SEVERE GEAR® 75W-85 provides advanced protection against wear, rust, and corrosion while reducing operating temperatures. The capacity for the front differential is 4.4 pints, and the rear is 3.4 pints. Proper lubrication here ensures the transfer case functions correctly and reduces wear on the gears during 4WD operation.
Cooling and Brake Systems
Maintaining the correct temperature is vital for the longevity of your engine. The cooling system capacity varies slightly depending on the specific configuration, with capacities noted at 13.1 quarts and 14.1 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 formulation that is phosphate-, nitrate-, and silicate-free, making it safe for all cooling system metals, gaskets, and hoses. It protects for up to 150,000 miles or five years. For those who prefer a concentrated product, the AMSOIL Propylene Glycol Antifreeze offers similar protection and requires mixing with distilled water. This product is also compatible with all other antifreeze colors and greatly surpasses standards for metallic corrosion.
Brake safety cannot be overlooked. The recommended hydraulic brake fluid for the Sequoia is DOT 3. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent responsiveness for ABS and traction control systems. Its synthetic formulation maintains a stable viscosity across a wide temperature range, ensuring consistent braking performance even during repeated stops or in varying weather conditions.
