2015 Nissan Altima Fluid Type Specs

Quick Reference

Engine Oil

For the 2015 Nissan Altima, the factory-recommended engine oil is a 0W-20 viscosity. It's crucial to use an oil that meets or exceeds the specifications of API SN/SP or ILSAC GF-5/GF-6. Using the correct oil ensures optimal engine protection, fuel efficiency, and longevity. Nissan specifically designs their engines to work with these modern, low-viscosity oils.

Capacity: The 2.5L 4-cylinder engine typically holds approximately 4.9 quarts (4.6 liters) of engine oil with a filter change. Always verify the exact capacity in your owner's manual, as slight variations can occur.

Intervals and Pitfalls: Nissan recommends oil and filter changes every 5,000 miles or 6 months, or as indicated by the vehicle's maintenance reminder system, whichever comes first under normal driving conditions. For severe driving conditions (frequent short trips, towing, extreme temperatures), more frequent changes may be necessary. Always use a high-quality oil filter to complement the fresh oil. Never use an oil with a different viscosity or specification than recommended, as this can lead to increased engine wear and potentially void your warranty.

Engine Coolant

Your 2015 Nissan Altima uses a specific Nissan Long Life Antifreeze/Coolant. This is an Ethylene Glycol-based, silicate-free, phosphate-free, and amine-free formula, typically identified by its blue color. It's designed for extended service intervals and is vital for preventing corrosion, maintaining proper engine temperature, and protecting against freezing and boiling.

Capacity: The cooling system capacity for the 2.5L engine is approximately 7.7 quarts (7.3 liters). When performing a drain and refill, you may not get all the old coolant out, so always monitor levels and top off as needed after bleeding air from the system.

Intervals and Pitfalls: Nissan recommends replacing the engine coolant every 105,000 miles or 84 months, whichever comes first. It is absolutely critical to never mix different types of coolants. Mixing OAT (Organic Acid Technology) and HOAT (Hybrid Organic Acid Technology) coolants, or using conventional green coolants, can lead to chemical reactions that cause gel formation, corrosion, and severe damage to your cooling system components, including the radiator, water pump, and heater core. Always use genuine Nissan coolant or an approved equivalent that specifically states compatibility with Nissan Long Life Blue coolant.

Transmission Fluid

The 2015 Nissan Altima is equipped with a Continuously Variable Transmission (CVT). This transmission requires a very specific fluid: Nissan NS-3 CVT Fluid. Using any other type of automatic transmission fluid (ATF), including multi-vehicle CVT fluids not specifically rated for NS-3, will almost certainly cause damage to the transmission and lead to costly repairs.

Capacity: The CVT fluid capacity is approximately 8.2 quarts (7.8 liters) for a drain and refill, but the exact amount can vary depending on the service procedure. CVT fluid changes are often best performed by a qualified technician due to specific fill procedures and temperature requirements.

Intervals and Pitfalls: Nissan's recommended service interval for CVT fluid can vary based on driving conditions. For many, inspection at 60,000 miles and replacement if driven under severe conditions (towing, frequent hilly driving, heavy city traffic) is a good guideline. However, consulting your owner's manual for specific recommendations based on your driving habits is always best. A common pitfall is using
