The 2001 Nissan Altima’s oil capacity depends on the engine in your car: the 2.4-liter four-cylinder uses about 4.5 quarts with a filter, while the 3.5-liter V6 uses roughly 5.1 quarts with a filter. Verify the exact figure for your vehicle by checking the engine code in the VIN or the owner's manual.
Engine options and oil capacity
The 2001 Altima lineup included two main engine choices. The oil capacity you need varies between them, so identifying the correct engine is important for an accurate change.
Oil capacities by engine
- 2.4L KA24DE four-cylinder: 4.5 quarts (with filter) [approximately 4.3 L]
- 3.5L V6 (VQ35DE): 5.1 quarts (with filter) [approximately 4.8 L]
These figures assume a standard oil change with a new filter. They do not account for variations due to overfill, different oil viscosities, or dealer-specific recommendations. Always confirm the exact capacity for your specific vehicle configuration.
Confirming the exact capacity for your car
Because the Altima could have either engine in 2001, confirming which powerplant is in your car ensures you use the correct oil quantity. Use the steps below to verify before performing an oil change.
To confirm the exact capacity, follow these steps:
- Locate the engine code on the engine block or on the vehicle’s service data plate under the hood.
- Check the VIN and the owner’s manual or a factory service bulletin to identify whether the engine is KA24DE (2.4L) or VQ35DE (3.5L).
- Match the engine code to the corresponding oil capacity figures listed above, and prepare the correct amount of oil plus a new filter.
Once you know your engine, use the matching capacity for a proper oil change and always recheck the level after the oil settles and the dipstick is read with the engine off and on level ground.
Summary
For the 2001 Nissan Altima, oil capacity depends on the engine: about 4.5 quarts for the 2.4L KA24DE and about 5.1 quarts for the 3.5L V6 (both figures include a filter). Always verify with the vehicle’s VIN, engine code, and the owner’s manual to ensure you use the correct quantity for your car.
