The 2002 Nissan Altima uses different oil capacities depending on the engine. The 2.5-liter inline-four uses about 4.5 quarts of oil with a new filter, while the 3.5-liter V6 uses about 5.5 quarts with a new filter.
These figures are typical baselines; actual capacity can vary slightly by model year or if you skip replacing the filter. Always confirm the level with the dipstick and refer to the owner's manual for your VIN-specific specification.
Engine-specific oil capacity
Overview
Before listing the practical figures, note that the numbers below reflect a complete oil change with a new filter installed for each engine variant.
- 2.5L inline-four (QR25DE): approximately 4.5 quarts of oil with the filter installed.
- 3.5L V6 (VQ35DE): approximately 5.5 quarts of oil with the filter installed.
When performing an oil change, using a new filter and allowing the oil to settle helps ensure an accurate final level on the dipstick.
Oil grade and maintenance tips
Practical guidelines
Before listing the recommendations, here are the standard guidelines for the Altima's oil type and change intervals.
- Viscosity: In most climates, Nissan recommends 5W-30 engine oil. In hotter or colder environments, your manual may allow 10W-30 or other grades; always verify for your specific engine and climate.
- Oil type: Conventional 5W-30 is acceptable; synthetic or a blend can offer better protection, especially in older or high-mileage engines.
- Change interval: Conventional oil is commonly changed every 3,000–5,000 miles (4,800–8,000 km) under typical driving. Synthetic oil can extend to about 7,500–10,000 miles (12,000–16,000 km) depending on driving and the owner's manual schedule.
Always follow the manufacturer's maintenance schedule and adjust intervals based on driving conditions, climate, and the engine's condition. After filling, recheck the level and ensure it's within the Full range on the dipstick.
Summary
The 2002 Altima's oil capacity depends on the engine: about 4.5 quarts for the 2.5L four-cylinder and about 5.5 quarts for the 3.5L V6, with a new filter. Use 5W-30 in most cases, and adhere to Nissan's maintenance schedule, checking the dipstick after filling to confirm the correct level.
