The engine is the heart of the 2016 Lexus ES350, and its longevity depends on the quality of lubrication it receives. The 3.5-liter V6 engine with the 2GRFE code is a robust unit designed for efficiency and power. When performing an oil change, the capacity is 6.4 quarts when the filter is replaced. It is crucial to adhere to the manufacturer’s viscosity recommendation of 0W-20, which offers the best balance of fuel economy and cold-weather starting capability. While 0W-20 is the primary recommendation, drivers should always check the dipstick after refilling to ensure the level is correct. The drain plug requires a torque of 30 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks.
For those seeking the ultimate level of protection, the AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil stands out as the top choice. This oil is engineered to protect against horsepower loss and wear, offering up to 25,000 miles of protection. It contains a higher concentration of performance-enhancing additives compared to conventional oils, ensuring that the engine runs cleaner and smoother for longer intervals. The extended service life capability means fewer oil changes, less waste, and reduced maintenance costs over the life of the vehicle. Additionally, it is guaranteed not to thin out at high temperatures or harden at low temperatures, maintaining its protective film across a wide range of driving conditions.
For drivers who prefer a slightly more affordable option without sacrificing the benefits of 100% synthetic technology, the AMSOIL OE 0W-20 100% Synthetic Motor Oil is an excellent alternative. It fights sludge and deposits effectively, ensuring that the internal components of the 3.5L engine remain clean. This formulation is particularly effective at preventing the accumulation of harmful byproducts of combustion that can lead to engine wear and reduced efficiency. It is a great choice for owners who want reliable protection that meets or exceeds original equipment specifications while adhering to a standard maintenance schedule.
As the 2016 Lexus ES350 ages, specific needs arise that require specialized attention. If your vehicle has accumulated over 75,000 miles, the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil is designed to address common issues found in older engines. It features a unique chemistry with boosted detergent and dispersant packages to clean out existing sludge, along with enhanced anti-wear additives to protect aging components. This formula reduces sludge by a significant margin, helping to restore performance and potentially improve fuel economy in older vehicles. The seal conditioners in this oil help to reduce oil consumption and leaks, keeping the engine running quietly and efficiently.
Filtration is just as important as the oil itself. The AMSOIL Oil Filter, product code EA15K02-EA, is specifically designed to maximize engine protection. It offers a filtration efficiency of 99 percent at 20 microns, capturing tiny wear-causing contaminants that could otherwise damage internal engine parts. The filter is constructed with a greater capacity for dirt and debris compared to competing filters, which helps extend the service life of the oil and the engine. For owners who prefer OEM-style filtration or a cost-effective solution, the WIX Oil Filter (57047-EA) offers premium media that outperforms many standard equipment filters.
Transmission and Drivetrain Maintenance
The 2016 Lexus ES350 is equipped with a U660E six-speed automatic transmission that requires specific fluid characteristics to ensure smooth shifting and longevity. The total fill capacity for this transmission is 6.9 quarts, with an initial fill of 3 quarts. Using a high-quality synthetic transmission fluid is essential for withstanding the rigors of daily driving, including heavy towing, elevated temperatures, and challenging terrain. The transmission fluid must remain fluid in sub-zero temperatures while providing adequate protection during heavy use.
The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to provide the highest level of protection for this transmission. It is engineered to minimize fluid degradation, ensuring consistent performance over extended periods. For those looking for a value-oriented option, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid also provides reliable protection against wear and helps maintain the integrity of the transmission’s internal components. Both products are formulated to exceed original equipment requirements, offering superior stability and performance in extreme driving conditions.
Cooling System and Brake Fluid
A properly functioning cooling system is vital for preventing overheating and engine damage. The cooling system capacity for the 2016 Lexus ES350 is 9.7 quarts. AMSOIL offers two primary antifreeze options: the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant (ANTPC1G-EA) and the AMSOIL Propylene Glycol Antifreeze and Engine Coolant (ANT1G-EA). The standard option is a 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or five years. The Propylene Glycol variant is a concentrated antifreeze that allows for custom mixing with water, offering protection for up to 150,000 miles or five years in passenger cars.
Brake safety cannot be overlooked. The 2016 Lexus ES350 uses a DOT 3 hydraulic brake system. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended for optimal stopping power and safety. This fluid provides excellent responsiveness for ABS and traction-control systems. Unlike conventional glycol-based fluids that absorb moisture over time, the synthetic formulation maintains a stable viscosity over a wide temperature range, ensuring consistent braking performance in hot or cold weather.
While the primary focus for vehicle maintenance is on internal fluids, exterior care and fuel system maintenance also play a role in the overall health and value of the vehicle. The AMSOIL P.i.® Performance Improver Gasoline Additive is a gasoline additive that can help restore fuel injectors to 100% flow rate, potentially restoring up to 14% of lost horsepower and improving fuel economy. It also helps prevent carbon buildup and pre-ignition knock, keeping the fuel system clean and efficient.
