Engine Oil

Specification: SAE 0W-20 API SN or SP Capacity: 5.3 quarts (5.0 liters)

For the 2023 Frontier, Nissan specifies a full synthetic SAE 0W-20 engine oil that meets API SN or the latest SP specification. Using the correct viscosity and quality of oil is critical for the longevity of the 3.8L V6 engine, ensuring proper lubrication and fuel economy. Always use a quality oil filter and change the oil every 5,000 miles or 6 months, whichever comes first.

Engine Coolant

Specification: Nissan Long Life Blue Coolant Capacity: 11.0 quarts (10.4 liters)

The Frontier comes factory-filled with a blue-colored, long-life coolant. When topping off or replacing the coolant, it is crucial to use the same Nissan Long Life Blue Coolant or a compatible equivalent. Mixing different coolant types can cause chemical reactions that may lead to gelling, reduced cooling efficiency, and potential damage to the cooling system. Never mix OAT, HOAT, or IAT coolants unless the product explicitly states it is compatible.

Automatic Transmission Fluid

Specification: Nissan Matic S ATF

This is a fill-for-life fluid under normal driving conditions, but severe-duty use may require fluid changes. The transmission is a sealed unit without a conventional dipstick. Checking the fluid level is a complex process that must be done at a specific temperature and should be performed by a qualified technician. Do not use universal or multi-vehicle ATFs. Using anything other than genuine Nissan Matic S ATF can lead to shift problems and premature transmission failure.

Transfer Case Fluid

Specification: Nissan Matic D or DEXRON-III/MERCON ATF Capacity: 2.1 quarts (2.0 liters)

For 4WD models, the transfer case requires an ATF-type fluid. You can use Nissan Matic D or an equivalent DEXRON-III/MERCON fluid. This should be changed according to the maintenance schedule, more frequently if you often use 4WD or tow heavy loads.

Front & Rear Differential Fluid

Front Specification: SAE 75W-90 Synthetic GL-5 Gear Oil Front Capacity: 1.8 quarts (1.7 liters) Rear Specification: SAE 75W-90 Synthetic GL-5 Gear Oil Rear Capacity: 2.9 quarts (2.75 liters)

Both the front and rear differentials on the 2023 Frontier require a high-quality synthetic gear oil with a viscosity of SAE 75W-90 and an API GL-5 rating. No friction modifier is required for the rear differential. Regular changes are vital for preventing gear wear, especially if you tow, haul heavy loads, or engage in off-road driving.

Brake Fluid

Specification: DOT 3

Use only DOT 3 brake fluid from a sealed container. Brake fluid is hygroscopic, meaning it absorbs moisture from the air, which can lower its boiling point and lead to corrosion in the brake lines and calipers. For this reason, it's important to flush the brake fluid every 2-3 years, regardless of mileage.

Power Steering Fluid

Specification: Genuine Nissan PSF or equivalent

The power steering system requires a specific fluid to function correctly. Use only Genuine Nissan Power Steering Fluid (PSF) or an equivalent that explicitly meets Nissan specifications. Using the wrong fluid can damage the pump and steering rack components.

Windshield Washer Fluid

Capacity: 5.3 quarts (5.0 liters)

There is no specific technical specification for washer fluid, but you should use a quality, solvent-based washer fluid appropriate for your climate. In winter months, a fluid with de-icing properties is recommended to prevent freezing on the windshield and in the reservoir.
