The heart of the 2009 FJ Cruiser is the 1GR-FE engine, a 4.0-liter V6 known for its reliability and torque. However, to keep this engine performing at its peak, the oil it uses must provide exceptional protection. The engine requires 5.5 quarts of oil when the filter is changed. AMSOIL Signature Series 5W-30 is engineered to provide up to 25,000 miles of protection, significantly reducing the frequency of oil changes compared to conventional standards while offering superior cleaning power. This ensures that the engine internals stay free of deposits and sludge, which is crucial for maintaining the engine’s longevity and smooth operation. For owners who prefer a lower cost option without sacrificing synthetic benefits, the OE 5W-30 or Extended-Life 5W-30 are excellent alternatives. Vehicles with over 75,000 miles will benefit from the 5W-30 High-Mileage Motor Oil, which features a boosted detergent package to help restore performance and reduce oil consumption.
Beyond the engine, the cooling system plays a vital role in the FJ Cruiser’s durability, especially given its off-road capabilities. The automatic transmission variant requires approximately 10.4 quarts of coolant, while the manual version needs about 9.9 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate, nitrate, nitrite, silicate, borate, and amine-free formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years. This concentrated, non-toxic fluid also reduces the risk of corrosion and scaling, ensuring the engine operates at optimal temperatures even under the most strenuous conditions. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated alternative that offers extended protection and is compatible with all other antifreeze colors.
The transmission system in the FJ Cruiser varies by model, with the automatic transmission (A750E or A750F) requiring roughly 11 quarts for a total fill, while the manual transmission (RA61) requires approximately 3.8 pints. Using the correct fluid is essential for preventing shudder and ensuring smooth shifts. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is rated for extreme conditions, withstanding the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero weather, providing reserve protection during heavy use. For those seeking a standard synthetic option, the AMSOIL OE Fuel-Efficient Automatic Transmission Fluid offers excellent wear protection. Manual transmission owners should utilize the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube, which protects brass synchronizers and offers long service life. Additionally, the differential and transfer case require specific lubricants to handle the 4WD system’s demands. The AMSOIL SEVERE GEAR® 75W-85 is ideal for the front and rear differentials, providing advanced protection against rust and corrosion while helping to reduce operating temperatures.
Maintenance extends to the braking system, where the FJ Cruiser utilizes DOT 3 hydraulic brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent ABS and traction-control responsiveness. Its stable viscosity over a wide temperature range ensures consistent braking performance, whether you are navigating a steep descent or an emergency stop. For owners looking to maximize engine performance and fuel economy, the AMSOIL P.i.® Performance Improver Gasoline Additive is a valuable addition. It restores up to 14% horsepower and cleans fuel injectors, ensuring that the V6 engine breathes efficiently and runs at peak efficiency.
