The 2012 Toyota Avalon with the 3.5L 6-cylinder engine (Code 2GRFE) is a full-size sedan designed for long-distance comfort, reliability, and efficient performance. To maintain this reputation for longevity, the engine requires precise lubrication that can withstand the rigors of daily driving while providing protection against wear. Using the correct viscosity and high-quality synthetic formulation ensures that the V6 engine operates smoothly, maintains fuel economy, and extends the service intervals between oil changes.

Selecting the right oil viscosity is critical for the 3.5L 6-cylinder engine. The manufacturer specifies a 5W-30 grade for all temperatures, which is an ideal balance for good fuel economy and reliable cold-weather starting. The engine oil capacity is 6.4 quarts when the filter is replaced. It is essential to check the oil level immediately after refilling to ensure proper lubrication. Additionally, the oil drain plug should be torqued to 30 ft/lbs to prevent leaks and ensure a secure seal.
Transmission and Drivetrain Fluids
For the 2012 Toyota Avalon, the automatic transmission (U660E model) plays a vital role in shifting performance and durability. The fluid needs to withstand high temperatures and heavy loads while remaining fluid in sub-zero conditions. For a partial fill, the capacity is 3 quarts, but a total fill requires 6.9 quarts. AMSOIL offers specialized transmission fluids designed to protect against wear, sludge, and temperature-related issues. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is an excellent choice for severe driving conditions, offering resilience against heavy towing and elevated temperatures. Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides robust wear protection and is ideal for those seeking OEM-equivalent performance. For power steering systems using AF3 fluid, the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid serve as compatible alternatives that guard against leaks and promote smooth, shudder-free shifts.
Coolant and Cooling System Maintenance
Maintaining the cooling system is equally important for the longevity of the Avalon’s engine. The cooling system capacity for this vehicle is 8.8 quarts. Using a high-performance antifreeze ensures that the engine does not overheat in the summer or freeze in the winter. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a ready-to-use, 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. For those who prefer a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers superior corrosion protection and a service life of up to 150,000 miles or five years. Both options are phosphate-, nitrate-, and silicate-free, making them compatible with all other coolant colors and safe for all cooling system components.
Brake Fluid and Safety Systems
Hydraulic brake fluid is a critical safety component that requires attention to ensure responsive braking and ABS functionality. The Avalon utilizes a DOT 3 fluid system. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed to provide excellent responsiveness for both ABS and traction control systems. It maintains a stable viscosity across a wide temperature range, ensuring consistent braking performance whether you are driving in stop-and-go traffic or on long highways. This fluid helps prevent the boiling and moisture absorption issues common in conventional brake fluids.
Seasonal Storage and Fuel Additives
For owners who utilize their Avalon seasonally, proper storage preparation is necessary to prevent fuel degradation and engine corrosion. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish, gum buildup, and ethanol corrosion. During storage, the AMSOIL Engine Fogging Oil provides a highly effective rust preventive for internal components. For those looking to restore performance or improve fuel economy, the AMSOIL P.i. Performance Improver Gasoline Additive can restore up to 14% horsepower and clean fuel injectors. Additionally, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor helps lubricate the fuel system and upper cylinders, offering protection compatible with capless fuel systems.
Filter Systems and Air Intake
A clean air intake is essential for engine efficiency and power. The WIX Air Filter offers premium media that improves upon OEM-branded filters, ensuring the engine breathes freely. Inside the cabin, the WIX Cabin Air Filters help trap dust and allergens, improving air quality for passengers. Regular filter changes complement the oil changes, ensuring that contaminants are kept out of the engine and cabin environment.
Vehicle Care and Protection
Beyond fluids and filters, maintaining the exterior and mechanical surfaces of the Avalon is important for preserving its value. The AMSOIL Silicone Spray creates a dry lubricating film that protects rubber and plastic components from cracking. For heavy grease and grime on the engine, the AMSOIL Engine Degreaser removes tough buildup quickly. Metal protection is available via the AMSOIL Heavy-Duty Metal Protector, which leaves a long-lasting wax-like coating against rust and corrosion. For general cleaning, the AMSOIL Miracle Wash Waterless Wash and Wax Spray allows for a quick wash and shine without water, protecting against UV rays. The AMSOIL Glass Cleaner effectively cuts through grease and grime on windows without leaving streaks. For a thorough interior clean, the AMSOIL Interior Detailer – Light Lemon and AMSOIL Interior Detailer – Scent Free provide multi-surface cleaning with 90-day UV protection and odor elimination.
