The 2023 Toyota Tacoma is a robust mid-size pickup truck designed for both daily commuting and serious off-road adventures. At the heart of this vehicle lies the 3.5L 6-cylinder engine (Engine Code 2GR-FKS 0), a sophisticated powerplant equipped with Dual VVT-i technology and a direct injection system. This engine architecture demands precise lubrication to maintain efficiency, power output, and longevity. Selecting the correct fluids goes beyond simply meeting the manufacturer’s base requirements; it ensures that the internal components of your Tacoma are protected against the extreme thermal stresses and friction inherent in modern driving conditions. Whether you are towing a heavy load on a mountain pass or navigating tight trails, the lubrication system is your vehicle’s first line of defense. Using high-quality synthetic lubricants can provide superior protection against wear, sludge, and deposits, ensuring that your engine runs smoothly for miles to come.

Engine Oil and Filtration Specifications
For the 2023 Toyota Tacoma’s 3.5L V6 engine, the manufacturer specifies a viscosity of 0W-20. This grade is the best choice for ensuring good fuel economy and providing reliable starting performance in cold weather conditions. The oil pan holds 6.2 quarts when the filter is replaced. It is crucial to refill the oil to the correct level and check the oil level after the refill. When reinstalling the oil drain plug, ensure a new gasket is used and tightened to the specified torque of 30 ft/lbs to prevent leaks.
AMSOIL Signature Series 0W-20 stands out for drivers who want the most from their vehicle, offering 75% more engine protection against horsepower loss and wear compared to industry standards. If you drive under severe conditions or require a balance of cost and performance, the AMSOIL OE variant fights sludge effectively. For vehicles that have accumulated over 75,000 miles, the AMSOIL High-Mileage formula provides boosted detergent packages and reduced sludge formation. To accompany your oil change, the AMSOIL Oil Filter ensures 99% filtration efficiency at 20 microns, which is critical for keeping small, wear-causing contaminants from recirculating. The WIX Oil Filter is also a solid choice for those who prefer established aftermarket brands, offering premium media that outperforms standard OEM filters.
Transmission, Differential, and Gear Lubrication
Proper transmission fluid is essential for the longevity of the Tacoma’s powertrain. Automatic transmission models equipped with the AC60F or AC60E series require specific attention. A total fill for these automatic units is 10.6 quarts, while an initial fill takes approximately 3.3 quarts. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated temperatures common in truck use, remaining fluid even in sub-zero environments. The AMSOIL OE Fuel-Efficient variant offers a reliable option that protects against wear and resists harmful sludge. For manual transmissions equipped with the RC62F unit, the recommended fluid is AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube, with a capacity of 5.3 pints. Drain and fill plugs should be torqued to 27 ft/lbs with new gaskets installed to ensure a secure seal.
Differential lubrication is another critical area for this vehicle. The front and rear differentials, as well as transfer cases, utilize GL-5 compatible fluids. The front differential requires 3.2 pints, while rear configurations vary based on the cab style. For the rear of the Access Cab, approximately 8 pints or 6.1 pints are needed depending on the configuration. For the DCAB with or without a lift bed, capacities range from 6.6 to 8.5 pints. The recommended lubricant for these heavy-duty applications is AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube. This fluid contains friction modifiers for limited-slip applications and helps control thermal runaway, keeping operating temperatures lower and extending the life of seals and equipment.
Other Essential Fluids and Additives
Beyond the drivetrain, the hydraulic systems in your Tacoma require high-quality fluids to operate safely and efficiently. For the braking system, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice. It offers excellent responsiveness for ABS and traction control systems while maintaining a stable viscosity across a wide temperature range. In the power steering system, which relies on a DEXRON-III Automatic Transmission Fluid specification, AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or the AMSOIL OE Multi-Vehicle version can be used to prevent leaks and ensure smooth, shudder-free operation.
Regarding cooling, the engine coolant capacity varies slightly between automatic and manual transmission models, with automatics holding 11.1 quarts and manuals holding 10.8 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles. For those preferring a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant allows for custom mixing and provides extended protection against corrosion and erosion. Seasonal storage requires attention as well; products like AMSOIL Gasoline Stabilizer help keep fuel fresh for up to 12 months, while AMSOIL Engine Fogging Oil protects internal components during periods of inactivity.
