Proper lubrication extends far beyond just the engine oil. For the 2012 Lexus ES350, maintaining the cooling system is equally critical. The engine requires a total coolant capacity of 9.4 quarts. AMSOIL offers two distinct antifreeze options to suit different owner preferences: the ready-to-use Passenger Car & Light Truck Antifreeze & Coolant or the concentrated Propylene Glycol Antifreeze and Engine Coolant. Both formulations are phosphate, nitrate, nitrite, silicate, borate, and amine-free, ensuring compatibility with all cooling system metals and preventing corrosion over extended periods of up to 150,000 miles or five years. The 50/50 pre-mix version simplifies the maintenance process, while the concentrated version allows for customization and potential cost savings on larger volumes.
Transmission health is another pillar of longevity for this vehicle. The 2012 ES350 utilizes a 6-speed automatic transmission (Model U660E), which requires specific synthetic fluid to operate correctly. A total fill of 6.9 quarts is necessary for this transmission, while an initial fill requires 3 quarts. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain, ensuring the fluid remains stable even in sub-zero conditions. For owners seeking a more budget-friendly alternative that still delivers top-tier performance, the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides excellent wear protection and meets fuel economy requirements without compromising on durability.
Brake system safety is paramount, and the fluid used must maintain its integrity under high stress. The 2012 Lexus ES350 utilizes a hydraulic brake system requiring DOT 3 compliant fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers a significant advantage over conventional glycol-based fluids. Its stable viscosity ensures consistent pedal feel and excellent responsiveness for anti-lock braking systems and traction control across a wide temperature range, reducing the risk of fluid boiling under heavy braking conditions. Additionally, for power steering systems that call for DEXRON-III, AMSOIL offers Multi-Vehicle Automatic Transmission Fluids in both Signature Series and OE grades, providing lubrication that resists harmful sludge and promotes smooth operation.
For owners focused on fuel economy and engine cleanliness, adding a fuel treatment can yield noticeable improvements. The AMSOIL P.i.® Performance Improver Gasoline Additive is designed to restore up to 14% of lost horsepower by cleaning GDI fuel injectors to 100% flow rate after just one tank of fuel. This additive helps prevent carbon buildup, which is particularly beneficial for direct injection engines, and can reduce the need for higher-octane fuel. It also controls pre-ignition knock and is compatible with capless fuel systems, making it a versatile choice for maintaining peak engine performance.
