Engine Oil

Type: SAE 0W-20 Spec: API SN, SN-PLUS, or SP; ILSAC GF-5 or GF-6A

For 2019, Toyota specifies SAE 0W-20 synthetic oil for both the 3.5L V6 and 2.7L I4 engines. Using a high-quality synthetic oil that meets the latest API (American Petroleum Institute) and ILSAC (International Lubricant Standardization and Approval Committee) standards is critical for the longevity of the engine's variable valve timing (VVT) system and overall efficiency.

Capacity:

• 3.5L V6 (2GR-FKS): 5.5–6.2 quarts (with filter). Always verify with the dipstick.
• 2.7L I4 (2TR-FE): 6.1–6.2 quarts (with filter). Always verify with the dipstick.

Interval: Toyota recommends an oil change interval of 10,000 miles or 12 months under normal driving conditions. For severe duty (towing, frequent short trips, dusty environments), a 5,000-mile or 6-month interval is advisable.

Pitfalls: Do not use heavier-weight oils like 5W-30 or 10W-30 unless in an extremely hot climate, and even then, consult your owner's manual. Using the wrong viscosity can lead to decreased fuel economy and potential VVT system issues.

Engine Coolant

Type: Toyota Super Long Life Coolant (SLLC) Spec: Pink, 50/50 pre-diluted

Toyota's SLLC is a high-quality, ethylene glycol-based OAT (Organic Acid Technology) coolant. It is specifically designed for the cooling systems of modern Toyota vehicles. It comes pre-diluted, so you do not need to add water.

Capacity: Approximately 10.1–12.9 quarts. The exact capacity can vary based on the specific configuration of the truck.

Interval: The "Super Long Life" name is no exaggeration. The factory fill is good for 10 years or 100,000 miles. Subsequent changes are recommended every 5 years or 50,000 miles.

Pitfalls: Never mix SLLC with other coolant types, especially traditional green IAT (Inorganic Acid Technology) or even other "long life" coolants like HOAT (Hybrid Organic Acid Technology). Mixing coolants can cause them to gel, leading to blockages and overheating. Never use "universal" coolants.

Transmission Fluid

Type: Toyota Genuine ATF WS (World Standard)

This is a specific, low-viscosity fluid formulated for Toyota's modern automatic transmissions. Its unique frictional properties are essential for smooth shifting and long-term durability.

Capacity: A full rebuild can be 10.5–11.1 quarts, but a typical drain-and-fill will be closer to 3–4 quarts. The Tacoma transmission does not have a dipstick, so level checks must be performed via a specific overflow plug procedure at a designated fluid temperature.

Interval: Toyota considers ATF WS to be a "lifetime" fluid. However, many technicians recommend a drain-and-fill every 60,000 miles, especially if you tow or frequently drive in mountainous terrain.

Pitfalls: Never, under any circumstances, use a universal or multi-vehicle ATF. The use of non-WS fluid will lead to shift problems, torque converter shudder, and eventual transmission failure.

Transfer Case & Differential Fluid

Transfer Case (4WD Models)

Type: Toyota Genuine Transfer Gear Oil LF 75W Note: Some dealer documentation or older manuals may refer to a standard 75W-90, but the LF 75W is the most current, specialized fluid.

Capacity: Approximately 1.1 quarts.

Front Differential

Type: Toyota Genuine Differential Gear Oil LT 75W-85 GL-5

Capacity: Approximately 1.6 quarts.

Rear Differential

Type: Toyota Genuine Differential Gear Oil LT 75W-85 GL-5

Capacity:

• Without Towing Package: ~3.2 quarts
• With Towing Package: ~4.4 quarts (larger axle housing)

LSD Note: The 2019 Tacoma uses an electronic "Auto LSD" system that works via the ABS and does not require a limited-slip differential additive.

Intervals: Toyota recommends inspecting differential and transfer case fluids every 15,000 miles and replacing as needed. A common-sense interval for a full fluid change is every 30,000–60,000 miles, depending on use (more frequently if off-roading or towing).

Brake Fluid

Type: DOT 3

While DOT 4 and DOT 5.1 fluids have higher boiling points and are technically compatible (as they are all glycol-based), DOT 3 is the factory specification and is perfectly adequate for all normal and most heavy-duty uses. Simply using fresh, clean DOT 3 is the most important factor.

Capacity: The system is filled as needed during bleeding, but a full flush usually requires about 1-2 quarts of fluid.

Interval: Bleed and replace every 2–3 years, regardless of mileage. Brake fluid is hygroscopic, meaning it absorbs moisture from the air, which lowers its boiling point and can cause corrosion in the brake lines and calipers.

Power Steering Fluid

The 2019 Toyota Tacoma is equipped with Electric Power Steering (EPS). It does not have a hydraulic power steering pump or use any power steering fluid. This is a maintenance-free system.

Washer Fluid

Type: Any high-quality washer fluid. Toyota Genuine Washer Fluid is available, but not required.

Use a freeze-resistant fluid in colder climates. In warmer climates, you can use a basic blue "all-season" fluid.

Capacity: Approximately 1 gallon.

Diesel Exhaust Fluid (DEF)

The 2019 Toyota Tacoma is only available with gasoline engines and therefore does not require Diesel Exhaust Fluid (DEF).
