Engine Oil

For the 2022 Toyota Tundra, the manufacturer specifies SAE 0W-20 engine oil. It is crucial to use an oil that meets or exceeds the American Petroleum Institute (API) classification SP and/or the International Lubricant Standardization and Approval Committee (ILSAC) specification GF-6. These ratings indicate the oil's ability to protect against low-speed pre-ignition (LSPI), improve fuel economy, and provide enhanced wear protection for modern engines.

The Tundra's i-FORCE 3.4L Twin-Turbo V6 engine has an approximate oil capacity of 7.7 to 8.2 quarts when the filter is replaced. Always confirm the exact capacity with your owner's manual or OEM service information, as slight variations can occur.

Intervals and Pitfalls: Toyota recommends engine oil and filter changes every 10,000 miles or 12 months under normal driving conditions. However, if you frequently tow, idle for extended periods, drive in dusty conditions, or make short trips in extreme temperatures, consider more frequent changes, typically every 5,000 miles or 6 months. Using an incorrect oil viscosity or spec can lead to reduced fuel economy, increased engine wear, and potential warranty issues.

Engine Coolant

The 2022 Toyota Tundra uses Toyota Super Long Life Coolant (SLLC), which is typically pink in color. This is a Hybrid Organic Acid Technology (HOAT) coolant. It is pre-mixed (50/50 water and coolant concentrate) and designed for extended service intervals.

The cooling system capacity is approximately 14.0 to 14.4 quarts, including the reservoir. Always check the coolant level when the engine is cold and ensure it is between the "LOW" and "FULL" marks on the reservoir.

Intervals and Pitfalls: Toyota SLLC has a very long service life, often recommended for replacement at 100,000 miles and every 50,000 miles thereafter. However, it's good practice to inspect the coolant level and condition periodically. Crucially, never mix Toyota SLLC with other types of coolants (e.g., conventional green, OAT coolants like Dex-Cool). Mixing different coolant chemistries can cause chemical reactions that lead to gel formation, corrosion, and severe damage to the cooling system and engine.

Transmission Fluid

The 2022 Toyota Tundra, equipped with the 10-speed automatic transmission, requires Toyota WS (World Standard) Automatic Transmission Fluid. This is a highly specialized, low-viscosity fluid formulated for optimal performance and durability in Toyota transmissions. There is no specified manufacturer spec number beyond "WS" as it is a proprietary Toyota fluid.

The total system capacity for the transmission fluid is approximately 12.0 to 13.0 quarts. However, a typical drain and fill will only replace a fraction of this amount, usually around 4-6 quarts, as a full flush requires specialized equipment.

Intervals and Pitfalls: Toyota generally considers the transmission fluid "lifetime" under normal driving conditions. However, for vehicles used for heavy towing, off-roading, or frequent driving in hot climates, it is advisable to consider a transmission fluid exchange or drain and fill at intervals such as 60,000 to 100,000 miles. Under no circumstances should you use a "universal" ATF or any fluid not specifically labeled as Toyota WS compatible. Using incorrect fluid can lead to harsh shifts, transmission damage, and ultimately, premature failure.

Transfer Case Fluid

For 4WD and AWD 2022 Toyota Tundra models, the transfer case requires a specific gear oil. The recommended fluid is SAE 75W, API GL-4, or Toyota Genuine Transfer Gear Oil LF. The "LF" designation indicates "Low Friction."

The transfer case capacity is approximately 1.1 to 1.6 quarts.

Intervals and Pitfalls: Toyota recommends inspecting the transfer case fluid every 30,000 miles and replacing it every 60,000 miles under normal conditions. If you frequently engage in heavy towing or off-road driving, consider more frequent changes, perhaps every 30,000 miles. Using a fluid that does not meet the specified GL-4 or Toyota LF requirements can lead to premature wear of the transfer case components.

Front Differential Fluid

The front differential of the 2022 Toyota Tundra requires SAE 75W-85, API GL-5 hypoid gear oil.

The capacity for the front differential is approximately 1.7 to 2.0 quarts.

Intervals and Pitfalls: Similar to the transfer case, the front differential fluid should be inspected every 30,000 miles and ideally replaced every 60,000 miles, especially if the vehicle is subjected to heavy loads or off-road use. Always ensure the fluid meets the GL-5 specification for adequate extreme pressure protection.

Rear Differential Fluid

The rear differential on the 2022 Toyota Tundra also specifies SAE 75W-85, API GL-5 hypoid gear oil. There is no specific mention of an Limited Slip Differential (LSD) additive being required for the factory differential as it typically uses an open or electronically controlled locking differential, which does not require friction modifiers.

The rear differential capacity is approximately 2.6 to 2.8 quarts.

Intervals and Pitfalls: Rear differential fluid change intervals mirror the front differential and transfer case: inspection at 30,000 miles, and replacement at 60,000 miles, or more frequently under severe service. Using an incorrect viscosity or an inferior quality gear oil can lead to increased wear and noise.

Brake Fluid

The 2022 Toyota Tundra exclusively uses DOT 3 brake fluid. It is a glycol-based fluid.

Intervals and Pitfalls: Brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can lead to corrosion in the brake system. Toyota generally recommends inspecting the brake fluid level at every service and replacing the fluid every 30,000 miles or every 2 years, whichever comes first. Never use DOT 5 (silicone-based) brake fluid, as it is incompatible with DOT 3/4/5.1 systems and can cause severe damage. While DOT 4 can be mixed with DOT 3, it is best practice to stick with the recommended DOT 3 to avoid potential issues or consult with a Toyota specialist if considering an upgrade.

Power Steering Fluid

The 2022 Toyota Tundra is equipped with an Electric Power Steering (EPS) system. This means there is no traditional hydraulic power steering pump or fluid reservoir to service. The system is electronically controlled and motor-driven.

Intervals and Pitfalls: Since there is no hydraulic fluid, there are no fluid-related maintenance intervals or pitfalls to consider for power steering on the 2022 Tundra.

Washer Fluid

The 2022 Toyota Tundra uses standard windshield washer fluid. Toyota recommends using Toyota Genuine Washer Fluid or an equivalent all-season type that provides adequate freeze protection for your climate. These fluids are typically methanol or ethanol-based.

Intervals and Pitfalls: Simply refill the reservoir as needed. Do not use plain water, especially in freezing temperatures, as it can freeze and damage the washer system components. Avoid using household detergents, as they can foam excessively and damage paint or rubber components.

Diesel Exhaust Fluid (DEF)

The 2022 Toyota Tundra does not offer a diesel engine option in North America. Therefore, Diesel Exhaust Fluid (DEF) is not applicable to this vehicle.
