Engine Oil

Specification: 0W-20 API SN or SP

Capacity: 4.8 - 5.1 quarts

The 2020 Nissan Altima comes with two engine options: the 2.5L four-cylinder (PR25DD) and the 2.0L VC-Turbo four-cylinder (KR20DDET). Both engines require a 0W-20 viscosity grade engine oil. While the owner's manual specifies API SN, the newer API SP specification is backward-compatible and offers superior protection against low-speed pre-ignition (LSPI), which is especially important for modern turbocharged, direct-injection engines like the VC-Turbo. Always use a full synthetic oil to ensure proper performance and longevity. Capacities vary slightly based on engine and drivetrain configuration, so it is always best to fill, run the engine for a minute, shut it off, wait a few minutes, and then top off as needed.

Engine Coolant

Specification: Nissan Blue L255N

Capacity: 7.5 - 8.2 quarts

Nissan specifies its "Blue" long-life coolant, part number L255N, for the 2020 Altima. This is a pre-mixed, ethylene glycol-based OAT (Organic Acid Technology) coolant. It is critical to not mix this with other coolant types, such as HOAT (Hybrid OAT) or IAT (Inorganic Acid Technology) coolants, as this can cause gelling and damage the cooling system. If you are not using the official Nissan fluid, ensure the replacement is a blue, Asian-vehicle compatible OAT coolant. The cooling system should be drained and filled every 5 years or 105,000 miles, whichever comes first.

Transmission Fluid

Specification: Nissan NS-3

Capacity: 7.4 - 8 quarts

The 2020 Altima is equipped with a Continuously Variable Transmission (CVT). CVTs are very sensitive to fluid type, and using the incorrect fluid can cause catastrophic failure in a very short time. You must use Nissan Genuine NS-3 CVT fluid. Do not use "universal" or "multi-vehicle" transmission fluids, even if they claim to be compatible. While some aftermarket brands offer NS-3 equivalent fluids, the safest bet is to stick with the OEM fluid from a Nissan dealership. The fluid level should be inspected regularly, and the fluid should be changed if it appears dark or burnt.

Transfer Case Fluid (AWD Models)

Specification: Nissan Matic-S

Capacity: ~0.5 quarts

For All-Wheel Drive (AWD) models, the transfer case requires Nissan Matic-S automatic transmission fluid. This is not a gear oil. Using a heavy gear oil in place of Matic-S will cause damage. The capacity is small, so it is an often-overlooked but critical fluid to maintain. The fluid should be inspected at regular service intervals and changed if any signs of contamination are present.

Rear Differential Fluid (AWD Models)

Specification: Nissan Matic-S

Capacity: ~0.6 quarts

Similar to the transfer case, the rear differential on AWD Altimas also specifies Nissan Matic-S ATF, not a traditional hypoid gear oil. This is a common point of confusion for technicians not familiar with this specific platform. Using a 75W-90 or similar gear oil will lead to improper lubrication and eventual failure of the differential clutches. Always double-check the service manual and use the specified Matic-S fluid.

Brake Fluid

Specification: DOT 3

Capacity: As needed

The brake system requires a standard DOT 3 brake fluid. While DOT 4 fluid has a higher boiling point and is technically compatible, it is also more hygroscopic (absorbs moisture faster) and is not necessary for this application. Stick with a quality DOT 3 fluid from a sealed container. Brake fluid should be replaced every 2 years, regardless of mileage, as it absorbs moisture from the air, which can lead to corrosion in the brake lines and calipers and reduce braking performance.

Power Steering Fluid

Specification: N/A

The 2020 Nissan Altima uses an electric power steering (EPS) system, so there is no hydraulic power steering pump, reservoir, or fluid to change.

Washer Fluid

Specification: Any

Capacity: ~1 gallon

Any commercially available windshield washer fluid is acceptable. In colder climates, use a fluid with a low freezing point to prevent damage to the reservoir and lines.
