Engine Oil Specifications and Selection
The 5.7L V8 engine in the 2009 Tundra is a powerful workhorse, but it demands precise lubrication to maintain its longevity. The manufacturer recommends a viscosity of 5W-20 for optimal operation. The oil capacity for this engine is 7.4 quarts when the filter is included. After refilling, it is crucial to check the oil level to ensure the correct amount is present.
For vehicle owners seeking the absolute best protection, AMSOIL Signature Series 5W-20 is the premium choice. Independent testing indicates it provides 75% more engine protection against horsepower loss and wear. This fluid is engineered to support extended drain intervals of up to 25,000 miles or one year, making it ideal for those who want to reduce maintenance frequency without sacrificing protection.
For drivers who prefer a balance between performance and cost, AMSOIL Extended-Life 5W-20 offers up to 20,000 miles of guaranteed protection. This formulation includes enhanced cleaning power to help keep the engine running smoother for a longer duration. Those who need a reliable, budget-conscious option that still delivers 100% synthetic performance can choose the AMSOIL OE 5W-20, which is designed to fight sludge and deposits effectively.
For Tundra owners with high mileage, specifically vehicles exceeding 75,000 miles, the AMSOIL 5W-20 High-Mileage Motor Oil is the specialized solution. It features a unique chemistry with boosted detergents and dispersants to clean sludge and reduce deposits, helping the engine perform better and last longer.
Filtration and Air Quality
Clean oil is only as effective as the filter keeping it clean. For this vehicle, the AMSOIL Oil Filter is highly recommended. It offers filtering efficiency of 99 percent at 20 microns, which helps remove small, wear-causing contaminants. This reduced restriction allows the engine to stay lubricated more efficiently compared to standard filters.
As an alternative, the WIX Oil Filter provides premium media that improves upon original equipment manufacturer filters. Maintaining clean air intake is equally important for engine efficiency. The WIX Air Filter is available to ensure optimal airflow, further supporting the engine’s combustion process.
Transmission and Differential Protection
The 2009 Tundra utilizes various automatic transmissions (A750F, A750E, AB60E, AB60F) depending on the configuration. Proper fluid maintenance is critical to prevent wear and maintain shifting smoothness. The total fill capacities vary by transmission type, ranging from 5.7 quarts to 6.4 quarts for a full service, though initial fills require less.
For superior protection against the rigors of towing and heavy loads, AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is the top recommendation. It remains fluid in sub-zero temperatures and resists breakdown under elevated heat. For those looking for a cost-effective synthetic option, the AMSOIL OE Fuel-Efficient Automatic Transmission Fluid provides reliable protection against wear.
The differential and transfer case require specific gear lubricants. The front differential and crew cab 4WD rear differential typically require a 75W-85 weight. For these applications, the AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is the perfect match. It controls thermal runaway and protects against rust and corrosion, extending the life of the gears and seals.
For other gear applications, such as manual transmissions or different GL-5 requirements, options like AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube or the heavy-duty AMSOIL SEVERE GEAR 75W-90 are available to handle increased heat and pressure.
Cooling, Braking, and Fuel Systems
The cooling system capacity depends on whether the vehicle has a tow package. Without the package, it holds 12.8 quarts, while models with the tow package require 13.7 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 formulation that protects all cooling system metals and is compatible with all antifreeze colors. For those who prefer mixing their own, the AMSOIL Propylene Glycol Antifreeze is a concentrated option for maximum protection up to 150,000 miles.
Braking performance is vital for a heavy vehicle like the Tundra. The recommended fluid is DOT 3. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness and a stable viscosity range, ensuring consistent braking even under hard use.
To maximize the efficiency of the 5.7L engine, fuel system cleanliness is key. The AMSOIL P.i. Performance Improver is a powerful gasoline additive that restores injectors to 100% flow rate, improves fuel economy, and helps prevent carbon buildup.
