2016 Toyota Tundra Fluid Specifications: A Master Tech's Guide

As an ASE-certified master technician, I’ve seen my fair share of trucks roll into the bay with premature wear simply because the wrong fluids were poured into them. The 2016 Toyota Tundra is a legendary workhorse, boasting either the 4.6L or the mighty 5.7L V8 engine. While these powertrains are famous for hitting the million-mile mark, they only do so if you maintain them meticulously using the exact factory-specified fluids.

Today, we are going diving deep into the exact fluid types, manufacturer specifications, and capacities you need to keep your 2016 Toyota Tundra running flawlessly.

Quick reference

Here is your master cheat sheet for the 2016 Toyota Tundra. Note that capacities can vary slightly depending on if your truck has the factory tow package (which includes supplemental coolers). Always verify exact capacities by checking the dipstick or fill-hole drip lines, and consult your owner's manual.

Fluid	Type/Spec	Capacity
Engine Oil (4.6L & 5.7L V8)	0W-20, API SN/SP, ILSAC GF-5/GF-6A	7.9 qts (with filter)
Engine Coolant	Toyota Super Long Life Coolant (Pink) / P-HOAT	13.7 - 15.0 qts (varies by tow pkg)
Transmission Fluid	Toyota Genuine ATF WS	11.6 - 12.3 qts (total dry fill)
Transfer Case (4WD)	Toyota Genuine Transfer Gear Oil LF 75W or 75W-90 GL-5	1.2 qts
Front Differential (4WD)	75W-85 GL-5 or 75W-90 GL-5	2.2 qts
Rear Differential	75W-85 GL-5 or 75W-90 GL-5	3.8 - 4.2 qts
Brake Fluid	DOT 3	System capacity (bleed until clean)
Power Steering	ATF DEXRON II or III	System capacity
Washer Fluid	Standard Automotive Washer Fluid	~ 4.0 - 5.0 qts
DEF (Diesel Exhaust Fluid)	N/A (Gasoline engines only)	N/A

Engine Oil

For both the 4.6L (1UR-FE) and 5.7L (3UR-FE) V8 engines, Toyota strictly specifies 0W-20 viscosity motor oil. The factory specification originally called for API SN and ILSAC GF-5, but the industry has since moved forward. Today, you should look for the backward-compatible API SP and ILSAC GF-6A certifications.

Capacities: Both V8s take right around 7.9 quarts when performing an oil and filter change.

Pitfalls & Intervals: Toyota states a 10,000-mile or 12-month interval under normal driving conditions. However, as a master tech, I highly recommend halving that interval to 5,000 miles or 6 months if you frequently tow, haul heavy loads, idle extensively, or drive in dusty environments. Never substitute 0W-20 with heavier weights like 5W-30 thinking it provides better protection; the tight tolerances and variable valve timing (VVT-i) mechanisms in these engines rely on the rapid flow of 0W-20 at startup.

Engine Coolant

The 2016 Tundra requires Toyota Super Long Life Coolant (SLLC), which is pre-mixed 50/50 and distinctly pink in color. This is a Phosphated Hybrid Organic Acid Technology (P-HOAT) coolant.

Capacities:

• 4.6L V8: Approx. 13.7 quarts.
• 5.7L V8: Approx. 14.1 quarts (can reach up to 15.0 quarts if equipped with the factory tow package and supplemental cooler).

Pitfalls & Intervals: The factory fill is rated for 10 years or 100,000 miles. Subsequent replacements should happen every 5 years or 50,000 miles. Never mix OAT or standard green silicate coolants with Toyota's pink SLLC. Mixing incompatible coolants can cause the additives to precipitate, forming a sludge that will rapidly clog your heater core and radiator. If you must use aftermarket coolant, ensure the bottle specifically states it is an equivalent P-HOAT formulation designed for Asian vehicles.

Transmission Fluid

The 6-speed automatic transmission (whether you have the AB60 or A760 series) strictly requires Toyota Genuine ATF WS (World Standard).

Capacities: A complete dry fill takes between 11.6 and 12.3 quarts. However, a standard drain-and-fill of the pan typically only yields about 3 to 4 quarts.

Pitfalls & Intervals: Toyota claims the ATF WS is a "lifetime" fluid under normal driving conditions, only requiring replacement every 60,000 miles if subjected to severe duty (towing, hauling). As a mechanic, I strongly advise performing a drain-and-fill every 60,000 miles regardless of how you drive. Do not use universal "multi-vehicle" ATF that claims to meet the WS spec. The WS fluid has a very specific friction modifier package designed for the slip-control lock-up clutch in Toyota torque converters. Using Dexron VI, Mercon LV, or ATF+4 will lead to harsh shifting and premature transmission shudder.

Transfer Case and Differentials (4WD)

If you have a 4x4 Tundra, you have three gearboxes to maintain.

• Transfer Case: Toyota calls for Toyota Genuine Transfer Gear Oil LF 75W. If you cannot find the specific 75W fluid, a high-quality 75W-90 GL-5 gear oil is an acceptable substitute. It holds roughly 1.2 quarts.
• Front Differential: Requires 75W-85 GL-5. A standard 75W-90 GL-5 is also acceptable and often easier to find. Capacity is about 2.2 quarts.
• Rear Differential: Also requires 75W-85 GL-5 (or 75W-90 GL-5). Capacity ranges from 3.8 to 4.2 quarts. Note: The 2016 Tundra uses an electronic simulated limited-slip differential (Auto LSD) which utilizes the brake system rather than traditional clutch packs inside the axle. Therefore, no special LSD friction modifier additive is required in the gear oil.

Pitfalls & Intervals: Change these fluids every 30,000 miles if you regularly tow, off-road, or submerge the axles in water. Always remove the fill plug before removing the drain plug! You don't want to drain your differential only to discover the fill plug is seized.

Brake Fluid

Toyota specifies standard DOT 3 brake fluid for the 2016 Tundra.

Pitfalls & Intervals: Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. This lowers the boiling point and rusts internal ABS components. Flush the brake system completely every 3 years or 30,000 miles. While DOT 4 is backward compatible with DOT 3 (it just has a higher boiling point), it absorbs moisture faster. Stick to a high-quality DOT 3 fluid as outlined by the manufacturer. Never use DOT 5, which is silicone-based and will destroy the ABS seals.

Power Steering Fluid

Interestingly, Toyota does not use a dedicated "power steering fluid" for this generation. The spec calls for ATF DEXRON II or III.

Pitfalls & Intervals: While there is no strict factory interval for power steering fluid, it gets dark and contaminated over time. I recommend a turkey-baster drain-and-fill of the reservoir every 30,000 miles to keep the rack and pinion seals happy. Do not put Toyota ATF WS in the power steering reservoir, even though the transmission uses WS. Stick to standard Dexron II/III ATF.

Windshield Washer Fluid

There is no special specification here. Any standard automotive windshield washer fluid will work. In colder climates, make sure to switch to a winter-blend fluid rated for sub-zero temperatures so you don't crack the reservoir or the washer pump.

Diesel Exhaust Fluid (DEF)

The 2016 Toyota Tundra was only produced with gasoline V8 engines. Therefore, it does not have a diesel particulate filter or an SCR system, and DEF is not required.
