2020 Nissan Titan Fluid Specifications and Capacities

As an ASE-certified master technician, I regularly get asked about the specific fluids required to keep a modern truck running in top shape. The 2020 Nissan Titan, equipped with the updated 9-speed automatic transmission and the robust 5.6L Endurance V8 (VK56VD), has some very specific fluid requirements. Using the wrong fluid—especially in the new transmission or the transfer case—can lead to costly premature wear, rough shifting, or complete component failure.

In this comprehensive guide, we will break down the exact factory-spec fluids, OEM part numbers, and capacities you need for your 2020 Nissan Titan.

Quick reference

Below is a quick reference chart for the 2020 Nissan Titan (5.6L V8 Gas). Note: The Cummins 5.0L Diesel was discontinued for the 2020 model year, so there is no DEF or diesel-specific oil listed here.

Fluid	Type/Spec	Capacity
Engine Oil	0W-20 API SN/SP, ILSAC GF-5/GF-6	6.5 qts (6.1 L) with filter
Engine Coolant	Nissan Blue Long Life Antifreeze (L255N)	3.6 gal (13.7 L)
Transmission Fluid	Nissan Genuine Matic P ATF	11.8 qts (11.2 L) total fill
Transfer Case (4WD)	Nissan Genuine Matic D ATF	1.6 qts (1.5 L)
Front Differential	80W-90 GL-5 Gear Oil	1.7 qts (1.6 L)
Rear Differential	Synthetic 75W-140 GL-5 Gear Oil	2.3 qts (2.2 L)
Brake Fluid	Genuine Nissan DOT 3 Brake Fluid	Fill to MAX line
Power Steering Fluid	Genuine Nissan PSF or Matic D ATF	1.1 qts (1.0 L)
Washer Fluid	Standard Washer Solvent	~1.2 gal (4.5 L)

Engine Oil

For the 5.6-liter Endurance V8, Nissan mandates the use of 0W-20 weight engine oil that meets API SN (or the newer API SP) and ILSAC GF-5 (or GF-6) standards. The capacity is 6.5 quarts when replacing both the oil and the filter.

Technician Notes: Using full synthetic 0W-20 is practically required due to the viscosity grade. The variable valve event and lift (VVEL) system on this engine is highly sensitive to oil pressure and viscosity. Sticking to the factory 5,000-mile or 6-month interval is highly recommended to prevent timing chain and VVEL actuator issues. Never substitute a thicker oil like 10W-30 thinking it will "protect better"—it will restrict flow to the top end of the engine.

Engine Coolant

The 2020 Nissan Titan requires Nissan Blue Long Life Antifreeze/Coolant (P/N 999MP-L25500P). This is a Phosphated Organic Acid Technology (POAT) coolant.

Technician Notes: Do not mix this with traditional green coolant, DEX-COOL, or universal "all makes, all models" coolants. Mixing POAT with HOAT or OAT coolants can cause the additives to fall out of suspension, leading to gel formation, clogged heater cores, and compromised water pumps. The factory fill is rated for 105,000 miles or 7 years. Subsequent replacements should be done every 75,000 miles or 5 years. Always use a 50/50 pre-mixed solution.

Automatic Transmission Fluid

For the 2020 model year, Nissan replaced the outgoing 7-speed transmission with an all-new 9-speed automatic transmission (built by Jatco). This unit requires Nissan Genuine Matic P ATF.

Technician Notes: Never use universal ATF, Matic S, Matic J, or Matic D in this transmission. Matic P is an ultra-low viscosity fluid specifically friction-modified for the 9-speed's clutch packs. Using the wrong fluid will result in harsh shifting, shuddering, and eventual failure. While Nissan claims this fluid is "lifetime," ASE best practices dictate performing a drain-and-fill every 60,000 miles, or every 30,000 miles if you frequently tow heavy loads. The total capacity is 11.8 quarts, but a standard drain-and-fill will yield significantly less. Always verify fluid level at the correct temperature using OEM service info.

Transfer Case Fluid (4WD Models)

If you have a 4x4 Titan, the transfer case takes Nissan Genuine Matic D ATF.

Technician Notes: This is a common pitfall! While the transmission uses Matic P, the transfer case still requires the older, thicker Matic D specification. Do not put Matic P or gear oil into the transfer case. A drain-and-fill takes about 1.6 quarts. Inspect this fluid every 30,000 miles and replace it at 60,000 miles (or sooner if submerged in water).

Differential Gear Oil

Front Differential: Requires 80W-90 GL-5 gear oil. The front differential handles less continuous load and relies on this standard viscosity. Capacity is about 1.7 quarts.

Rear Differential: Requires a much heavier Synthetic 75W-140 GL-5 gear oil. The Titan uses a robust rear axle designed for towing, generating higher internal temperatures, hence the need for 75W-140 full synthetic. Capacity is approximately 2.3 quarts.

Technician Notes: The 2020 Titan utilizes an electronic locking rear differential (on PRO-4X models) or an open differential with brake-actuated limited slip. Neither requires a traditional friction modifier additive for clutch-type limited-slip differentials (LSD). Change your differential fluids every 30,000 miles if you tow regularly.

Brake Fluid

Nissan specifies Genuine Nissan Super Heavy Duty Brake Fluid or equivalent DOT 3.

Technician Notes: DOT 4 can be used as a substitute if DOT 3 is unavailable, as it has a higher boiling point and is backward compatible, but it absorbs moisture faster and requires more frequent changes. Never use DOT 5 (silicone-based) as it will destroy the ABS modulator seals. Flush the brake fluid every 2 years or 20,000 miles to prevent internal corrosion of brake calipers and master cylinder components.

Power Steering Fluid

The 2020 Titan still uses a hydraulic power steering system, requiring Genuine Nissan PSF or equivalent Dexron VI / Matic D ATF.

Technician Notes: Keep an eye on fluid color and smell. If it turns dark brown or smells burnt, it is time for a flush. A turkey-baster drain and fill of the reservoir at every oil change is a great, cheap way to keep the fluid fresh without a complete flush.

Windshield Washer Fluid

Use any high-quality washer fluid appropriate for your climate. In freezing temperatures, ensure the fluid is rated for winter use (typically -20°F or lower) to prevent the reservoir tank and lines from freezing and cracking.

Proper fluid maintenance is the lifeblood of your Nissan Titan. Using factory-specified fluids prevents catastrophic failures, ensures optimal performance, and keeps your warranty intact. If you don't have the tools, time, or flat ground to perform these services properly yourself, don't risk it.
