The 1AR-FE engine in the 2016 Highlander is a robust 2.7-liter inline-four that balances power with efficiency. To keep this engine running smoothly, the oil capacity is 4.6 quarts when the filter is changed. This specific volume is critical to ensure proper lubrication of all moving parts, from the crankshaft bearings to the variable valve timing system. Failing to fill to the correct level or using an oil that does not meet the 0W-20 viscosity requirement can lead to increased friction, reduced fuel economy, and potential engine wear over time.
When performing an oil change, it is essential to install a new washer on the drain bolt and torque the oil drain plug to 30 ft/lbs. Regular maintenance also involves checking the oil level after refilling the system. For owners of this vehicle with high mileage, the unique chemistry in the high-mileage motor oil can help address issues like oil consumption and sludge buildup, extending the life of the engine components.
Beyond the engine, the 2016 Highlander’s automatic transmission (specifically the U760E model) requires attention. A total fill for this transmission requires 6.9 quarts, while an initial fill is 2.9 quarts. Using a high-quality synthetic automatic transmission fluid helps protect the transmission from sludge and temperature-related problems, ensuring smooth gear shifts and reducing wear on internal bands and clutches. The fluid remains fluid even in sub-zero temperatures, providing reliability in various climates.
For the drivetrain, the transfer case and rear differential require specific gear lubricants. The transfer case holds 1.7 pints, and the rear differential requires 1.1 pints. Both components benefit from the use of AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube, which helps control thermal runaway and reduces operating temperatures. This lubricant also contains friction modifiers that are particularly beneficial for limited-slip differentials. Proper torque specifications for the fill and drain plugs on these components are 36 ft/lbs, and new gaskets should always be installed on the drain and fill plugs to prevent leaks.
The cooling system is another critical area, with a total capacity of 10.7 quarts. Maintaining the correct antifreeze mixture is vital for preventing overheating during hot summer drives or freezing during cold winters. AMSOIL antifreeze products are engineered to exceed original equipment manufacturer requirements, offering protection up to 150,000 miles or 5 years. These formulations are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all cooling system metals, gaskets, and hoses without causing damage.
Brake fluid performance is often overlooked but is essential for safety. The recommended fluid for the 2016 Highlander is a DOT 3 hydraulic brake fluid. AMSOIL’s synthetic brake fluid provides stable viscosity across a wide temperature range, ensuring responsive braking and excellent traction control. This fluid is a superior alternative to conventional fluids, offering better protection against moisture absorption and boiling points that are crucial for consistent brake performance.
