The 2015 Nissan Altima is known for its smooth ride, fuel efficiency, and long-lasting engine performance. Whether equipped with the reliable 2.5L 4-cylinder engine or the more powerful 3.5L V6, using the correct engine oil is one of the most important maintenance steps for keeping your Altima running properly.
Using the proper oil viscosity and maintaining regular oil changes helps improve fuel economy, reduce engine wear, prevent sludge buildup, and extend overall engine life. Modern synthetic oils also provide superior protection during extreme temperatures and stop-and-go driving conditions.
What Type of Oil Does a 2015 Nissan Altima Take?
The recommended oil type for the 2015 Nissan Altima is SAE 0W-20 full synthetic motor oil. Nissan designed the Altima engine to operate with low-viscosity synthetic oil for improved fuel economy, smoother cold starts, and better engine protection.
Drivers living in extremely hot climates may occasionally use 5W-30 synthetic oil if recommended by a mechanic, but Nissan primarily recommends 0W-20 for most driving conditions.
2015 Nissan Altima Oil Capacity
The engine oil capacity for the 2015 Nissan Altima depends on which engine is installed. Always check the oil dipstick after refilling to verify the proper oil level.

Reduced Fuel Economy
Old oil can reduce engine efficiency and negatively impact gas mileage.
How to Check Oil in a 2015 Nissan Altima
Checking the oil level regularly helps prevent engine damage and ensures proper lubrication.
- Park the vehicle on a level surface.
- Turn off the engine and wait several minutes.
- Pull out the dipstick and wipe it clean.
- Reinsert the dipstick fully.
- Remove it again and check the oil level.
- Add 0W-20 synthetic oil if the level is low.
Can You Use 5W-30 Instead of 0W-20?
