Using the correct viscosity of motor oil is the first line of defense for the Avalon’s 3.5L V6 engine. The factory-recommended 0W-20 grade is ideal for ensuring optimal fuel economy and easy cold-weather starting. However, simply pouring oil into the crankcase is only part of the equation. The engine requires a robust filtration system to capture the microscopic contaminants that can cause premature wear. The AMSOIL Oil Filter works in tandem with the synthetic oil to capture smaller particles than standard filters, ensuring that the oil stays cleaner for longer periods. This synergy allows drivers to extend their oil change intervals significantly compared to conventional oil change schedules, reducing maintenance costs and environmental impact while maximizing engine life.
Fluids are often overlooked in favor of oil changes, but the cooling and transmission systems are equally vital to the health of the Avalon. The engine cooling system must operate efficiently to prevent overheating, which can warp cylinder heads and damage gaskets. AMSOIL Antifreeze & Coolant offers a unique formulation that exceeds original equipment requirements, protecting all cooling system metals, gaskets, and hoses from corrosion and scaling. It is phosphate, nitrate, and silicate-free, ensuring compatibility with modern engine materials. The capacity for this system is approximately 9.7 quarts, so selecting a high-performance coolant ensures that the 50/50 pre-mix formulation maintains its protective properties throughout the lifespan of the fluid.
Transmission fluid plays a critical role in the Avalon’s smooth operation, especially given the U660E 6-speed automatic transmission. This transmission handles everything from daily commuting to towing, requiring a fluid that can withstand elevated temperatures and heavy loads. Standard automatic transmission fluid can degrade over time, leading to shuddering, harsh shifts, and eventually, transmission failure. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand these rigors, remaining fluid in sub-zero temperatures and providing reserve protection during heavy use. It is designed to reduce friction and wear, ensuring that the Avalon shifts smoothly and efficiently for the long haul.
In addition to the core drivetrain fluids, other maintenance products play a supportive role in keeping the Avalon in top condition. The braking system relies on high-quality AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid to function safely. Over time, brake fluid absorbs moisture, which can lower its boiling point and cause corrosion in the master cylinder and calipers. Switching to AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides a stable viscosity over a wide temperature range, ensuring consistent pedal feel and excellent responsiveness for ABS and traction control systems. For seasonal storage or vehicles that sit for extended periods, using AMSOIL Engine Fogging Oil and AMSOIL Gasoline Stabilizer can prevent rust formation and fuel degradation, keeping the engine ready to start when needed.
