The 2015 Nissan Altima offers practical daily driving with a clear maintenance schedule centered on the right oil capacity. Knowing the exact amount helps protect the 2.5-liter four-cylinder and supports long term reliability.
Below is a quick reference for fluids, capacities, and filter sizes tailored to the 2015 Nissan Altima platform.
| Fluid | Capacity | Filter Type | Notes |
|---|---|---|---|
| Engine Oil | 4.5 quarts (with filter) | Standard cartridge | Refill about 4.0 quarts after filter change |
| Automatic Transmission | 10.8 quarts | N/A | Includes torque converter and pan |
| Coolant | 12.2 quarts | N/A | Mix with distilled water 50/50 |
| Power Steering | 0.9 quarts | N/A | ATF type fluid, Nissan NS-2 spec |
| Brake Fluid | N/A | DOT 3 or DOT 4, avoid moisture contamination |
2015 Nissan Altima Engine Oil Capacity Details
With a 2.5-liter four cylinder under the hood, the 2015 Nissan Altima holds about 4.5 quarts of engine oil when including the filter. This total accounts for roughly 4 quarts poured into the oil pan plus the small amount stored by the new filter. Using the recommended 0W20 viscosity supports fuel efficiency while keeping high mileage components protected.
For owners switching between DIY top offs and full changes, pouring slightly more than 4 quarts into the fill neck prevents underfilling. Always check the oil level with the engine off and on level ground for the most accurate reading on the dipstick.
Nissan specifies this capacity and oil type in the owner manual and on the oil cap, so follow those sources before any service work. Adhering to factory numbers helps maintain the factory warranty and supports smooth acceleration with the continuously variable transmission.
2015 Nissan Altima Transmission And Fluid Needs
The automatic transmission in the 2015 Altima typically requires about 10.8 quarts for a complete flush and refill. This figure covers fluid inside the torque converter, the valve body, and the gear sets housed in the pan.
Because most owners cannot accurately measure the transmission level with the pan removed, many rely on a full service from a professional using the correct Nissan ATF. Using the wrong fluid can harm shift quality and long term durability of the planetary gear set.
For the power steering system, a modest 0.9 quarts of compatible fluid is usually enough for a standard replacement cycle. Keeping this topped at the recommended interval reduces steering growl and makes parking smooth around tight corners.
Coolant, Brake Fluid, And Other Key Capacities
The cooling system on the 2015 Altima holds roughly 12.2 quarts of antifreeze mixture, which allows the 2.5-liter engine to run within a safe temperature range in hot and cold climates. Routine refills and a proper 50/50 mix with distilled water prevent scale buildup inside the radiator and heater core.
Brake maintenance is simpler, with about 1.0 quart of DOT 3 or DOT 4 fluid needed to fill the master cylinder and caliper circuits. Fresh brake fluid absorbs less moisture over time, so scheduled flushes support consistent pedal feel and reliable stopping distances in everyday driving.
Following the recommended capacities reduces the risk of air pockets, leaks, and component wear. Staying on top of oil, coolant, and brake fluid changes keeps the Altima dependable on long commutes and weekend trips.
Key Takeaways For 2015 Nissan Altima Owners

- Transmission fluid flush calls for about 10.8 quarts of ATF.
- Use 0W20 viscosity for optimal fuel efficiency and engine protection.
- Check coolant and brake fluid levels regularly as part of routine care.
- Always reset the oil life monitor after completing an oil change.
FAQ
Reader questions
How much engine oil does a 2015 Nissan Altima take with the filter?
A 2015 Nissan Altima with the 2.5-liter engine requires about 4.5 quarts of engine oil when including the oil filter.
Can I use 5W20 instead of 0W20 in my 2015 Altima?
For best results, stick with 0W20 as specified, but 5W20 is generally acceptable if 0W20 is unavailable and still meets the ILSAC GF-5 or dexos1 standard.
How often should I check the oil level on my 2015 Altima?
Check the oil level at least once a month and always before long trips to catch low readings early and prevent engine stress.
Do I need to reset the oil life monitor after a change?
Yes, resetting the oil life monitor after a service helps the vehicle accurately track the remaining drain interval based on actual usage.
