2017 Nissan Altima Fluid Type Specs

Quick reference

Engine Oil

For your 2017 Nissan Altima, the manufacturer specifies 0W-20 full synthetic engine oil. It is crucial to use an oil that meets or exceeds API SN or SP standards and ILSAC GF-5 or GF-6 specifications. These designations ensure the oil provides adequate protection against wear, sludge, and piston deposits, while also contributing to fuel economy.

Capacity: The engine typically requires 4.9 US quarts (4.6 liters) when the oil filter is replaced. Always double-check the level with the dipstick after filling and running the engine briefly to circulate the oil.

Intervals and Pitfalls: Nissan recommends oil changes every 5,000 miles or 6 months, whichever comes first, under normal driving conditions. For severe driving conditions (frequent short trips, towing, extreme temperatures, or dusty environments), more frequent changes are advisable. Using an incorrect oil weight or a non-synthetic oil can lead to premature engine wear, reduced fuel efficiency, and potential warranty issues. Avoid extending oil change intervals beyond the recommended guidelines, as this can lead to oil breakdown and sludge accumulation.

Engine Coolant

The 2017 Nissan Altima uses Nissan Long Life Antifreeze/Coolant (Blue). This is a special long-life, ethylene glycol-based coolant that is silicate-free, amine-free, and nitrite-free, designed for extended service intervals. It is pre-mixed and should not be diluted.

Capacity: The cooling system capacity is approximately 7.8 US quarts (7.4 liters).

Intervals and Pitfalls: Nissan typically recommends replacing the engine coolant every 105,000 miles or 7 years. It is critical to use only the specified Nissan Long Life Antifreeze/Coolant (Blue). Never mix different types of coolants (e.g., OAT with HOAT or conventional green coolant) as this can lead to chemical incompatibilities, gel formation, and severe damage to the cooling system components, including the radiator, water pump, and heater core. Always allow the engine to cool completely before checking or adding coolant, and be exceptionally careful when opening the radiator cap on a warm engine due to the risk of scalding hot fluid and steam.

Transmission Fluid

Your 2017 Nissan Altima is equipped with a Continuously Variable Transmission (CVT). This transmission requires a very specific fluid: Nissan NS-3 CVT Fluid. The use of any other type of transmission fluid can cause severe and irreversible damage to the CVT, leading to costly repairs.

Capacity: The capacity for the transmission fluid can vary. It is always best to consult your owner's manual or OEM service information for the precise capacity, as draining and refilling typically only replaces a portion of the total fluid. A full flush requires specialized equipment.

Intervals and Pitfalls: Nissan recommends inspecting the CVT fluid level regularly and changing it according to the maintenance schedule outlined in your owner's manual. Under severe driving conditions, such as heavy city driving, towing, or hot climates, more frequent fluid changes may be necessary to maintain optimal transmission performance and longevity. **Never use
